The Ultimate FAQ Guide to Lockable Electrical Enclosures

Why do my enclosures need locks?

Enclosures may have important and even dangerous electrical components.

Locks prevent unauthorized people from tampering with or even stealing the instruments, devices, and controls housed in the enclosure.

This is especially important for enclosures located in public places, or those in hazardous facilities.

Examples of public areas include guesthouses, airports, apartment buildings, stores, and even business centers.

On the other end of the spectrum, hazardous facilities include fire fighting places, construction sites, various factories, research labs.

Other locations you should lock your enclosures in include highways, anywhere on the street, maybe even personal homes.

Lockable enclosures can be useful not only for industrial electrical components but also for medical storage areas and testing devices.

What standard designs of locks are there?

Among our designs, we offer many types of locks, including cam locks, key-lock handles, key insert locks, T-handle locks, and deadbolts.

Cam locks are simple and affordable.

They are commonly used to lock cabinets, mailboxes, and other low-security applications.

So, if you need to secure a very important device, a cam lock may not be for you.

Cam locks are made of a cylindrical base and a cam, which is a metal piece that lets the cover open once a key pushes it up.

There are multiple types of cams, such as straight, hooked, and offset, that offer different levels of complexity.

These locks can rotate clockwise and counter-clockwise, limited to 90 or 180 degrees.

 Cam lock

Key-lock handles fulfil the roles of a handle and a lock.

Usually, you need a key for these that unlock the handle, the turn of which unlocks the door.

It could also be the other way around – first the turn of a handle, and then the key.

Another option is to make the handle act as the lock when a specific turn unlocks the door without needing a key.

Windows usually have this type of a lock.

Key-lock handles

Insert locks just refer to any lock that needs a key to open it.

This includes cam locks, key-lock handles, but also euro profile locks.

Euro profile locks are popular in Europe but are also sometimes used in North America.

They look like a circle with an oval on the bottom.

They are attached by one screw and are simple.

They are also called DIN cylinders.

Their disadvantage lies with that one screw since it is easy to break to open the enclosure.

Euro profile lock

T-handle locks are easy to install and replace since they are taken out every time the lock is opened.

They come in 2 types: spring latch and dead latch – one doesn’t need a key and the other one does.

T-handle lock

Finally, deadbolts are some of the most reliable locks you can find.

It has a cylinder for the key and a bolt that rests in the cover, preventing it from opening.

Once a key is inserted, the bolt moves, letting the cover open.

Deadbolt lock

What “turn” types of locks are there?

The two most common types of locks are quarter-turn and 3-point-turn locks.

This just describes the mode of operating the lock.

Quarter-turn locks are usually cam locks.

They are simple and provide moderate security.

On the other hand, 3-point-turn locks are more protected and heavy-duty.

Usually, 3-point-turn locks are hidden in the handle or somehow operate with the handle, creating a more complex locking system.

 3-point-turn lock

The electrical enclosures with 3-point locks are used in food-processing plants, pharmaceutical manufacturing facilities, petrochemical plants, pulp and paper processing, water treatment facilities, and food packaging applications.

Finally, 3-point latches are water-tight, not requiring additional sealing.

What additional design features are there for enclosure locks?

One particular design feature we are proud to offer is an alarm locking system if you want.

It is similar to a lockout, making it impossible to open the lock if an alarm is sounded.

This also could mean that an alarm is tripped if someone is tampering with the lock.

Can I request a combination lock?

You can always talk to our Research and Development team to design a combination lock, which is a digital lock or a physical padlock requiring a code to open it.

Padlocks are easier to develop into combination locks, whereas digital ones are more intricate since they need a source of power and need to be protected from hazards.

Plus, digital combination locks can glitch, which is not good in a dangerous situation.

Combination locks: columnar and circular

Overall, though, combination locks are good because then the risk of losing keys is eliminated.

Plus, combination locks are less prone to tampering, and with one, your enclosure practically becomes safe.

What parts does a lock/lockable enclosure consist of?

Of course, this depends on the type of lock you choose, any additional features of the enclosure, such as windows, and the material of the enclosure.

Although, generally, popular configurations go by the following.

A lockable enclosure can have two long rods that are attached vertically from top to bottom inside the door.

It also features a strong lock with a removable lever or handles, a polycarbonate crew, and a mounting base for easier installation.

Where should locks be placed?

This is completely up to you.

You can request the lock to be on the right, left, up, down, or dead center of your enclosure’s front panel.

The lock can even be on the top, bottom, or back panels to make it more hidden.

To choose the location of the lock, consider what you want to accomplish.

If you want to hide it, then placing it on any panel except for the front one will work.

Besides the panels mentioned above, you can also place the lock on the side or even the bottom panels – if the enclosure is wall-mounted.

If you just want to secure the enclosure, place the lock somewhere where it would be convenient for personnel to access it.

This means placing the lock roughly at the level of an average worker’s waist.

How many locks per enclosure should there be?

The short answer is: as many as you need.

Usually, enclosures only have one lock, but there can be more if the enclosure has several doors or compartments.

Specifically, there can be one, two, or multiple doors per enclosure, and each can have its own lock.

Plus, our custom enclosures and cabinets may have several drawers, and you can request a lock on as many of these as you want – be it one or all of them.

  Cabinet with drawers

Besides that, you can have double locks, which is when the base of the lock is one, but you need two or more locks to open it.

This increases the security of the enclosure, so it could be useful for those containing control systems.

Finally, you can have a lock on the door/cover and one on the window – for quicker access to most important components as well as backup overall access.

Plus, if you have a lockout, you will have many locks per door – see the section below.

Is there a difference between locks, padlocks, and safety lockouts?

“Lock” is an overarching term that includes padlocks as well.

Usually, though, when we talk about locks, we mean internal locks that are installed into an enclosure.

On the contrary, padlocks are external locks that hang from the cover.

These can be broken, so using them for important enclosures is not ideal.

Type of lockout

Lockouts are very elaborate padlocks that are placed on a machine or equipment to prevent anyone from accessing it until maintenance is complete.

This is useful in research and power plant facilities where there is dangerous electrical equipment.

What is an interlock and a defeater mechanism?

Electrical interlocks are locks designed to keep the cover or door handle of an enclosure from turning. Also, they keep covers/doors from being opened.

There are devices called the interlock defeaters.

They are key-operated switches that disable the interlocks to allow access for maintenance.

Interlocks operate similarly to lockouts, but not allowing entry while the machine is running, or is energized.

  Interlock

Defeater mechanisms disable the interlock, as well as other possible lockout mechanisms.

They are usually circuit breakers that have a pin which moves a lever inside the interlock device to cut its circuit to open the cover/door.

  Interlock with defeater

Defeaters are not tools, but rather are part of the interlock that allows a tool to be used to disengage the interlock.

What types of latches are there?

Latches aren’t as secure as locks, but they are still good.

The two main latches you can have are hang latches and spring latches.

Hang latches have a hook and a loop.

Needless to say that this latch is not very secure and all it does is keep the door from swinging open.

Hang latch

The other type, spring latch, is a little more secure because it can take a moment to figure out.

Basically, there is a hook and a loop, as well as a spring-loaded base that keeps the latch secure.

Once this base is lifted up, the loop slips from the hook, opening the door.

Spring latch

Plus, you can request a crossbar latch, but those are not typically used for enclosures.

We also offer separate latch kits that you can add to your existing enclosures.

How can I design handles?

Besides the typical handle and lever designs presented above, there are other ways you can design your lockable handles.

One way to incorporate a lock into the handle is by hiding it.

You can place a sliding cover over the lock.

Once that cover is pushed away, the lock can be unlocked, letting you move the handle, which opens the door.

Another idea is to place the lock behind the handle, so it can only be accessed once the handle is pushed away.

Hidden lock

Another handle is known as the paddle lock.

This handle is a rectangular piece that you push out to open the door.

The lock is usually right next to it.

This handle is commonly used with heavy-duty enclosures.

Also, you can have a handle that covers the lock but can be slid away to show it.

Then, after the lock is unlocked, the handle can be used as it is usually used.

Paddle lock

One more interesting handle you can have is a twisting knob that you can turn to unlock the door.

A lock can be incorporated to block the twisting of the knob until the lock is locked.

 Twisting knob

Does the material used for locks differ from material used for the rest of the enclosure?

The materials used for enclosures aren’t different from materials used for locks.

Locks, like our enclosures, can be made from acier au carbone, galvanized steel, and stainless steel – usually of the grade 304.

Keep in mind that each has certain qualities.

Galvanized steel is heavy, while carbon steel can be dented more easily.

Stainless steel is more expensive, but it is the strongest of the bunch.

Plus, the handles can be made from these steels, as well as from polycarbonate and ABS.

Polycarbonate is more resistant to corrosion, whereas ABS is cheaper.

What enclosures can be paired with locks?

Any other enclosures you want!

You can put a lock onto a free-standing enclosure, a wall-mounted enclosure, a junction box, any industry enclosure, a custom enclosure.

Basically, any enclosure we offer can be paired with a lock.

Especially, locks are great for junction boxes with operator interfaces since important control systems are likely to be housed there.

  Junction box

You can also add other features to your enclosure besides locks, such as vents, windows, and hinges.

Vents help cool down the contents of the enclosure.

When electrical components run, they produce heat that can damage these components.

Thus, vents deal with that heat.

Windows provide a view of the instruments and gauges housed in the enclosure.

This makes maintenance and diagnostic work faster since everything is visible.

Hinges help open the cover/door.

How protected can lockable enclosures be?

Your lockable enclosures can be IP or NEMA rated as well.

IP enclosures are rated with the IP code, which has 2 digits – one for protection against solid ingress and another against liquid.

The maximum IP protection an enclosure can have is IP69K, which is fully dust-tight and can be submerged underwater for a long time and sprayed with hot pressurized water.

We offer enclosures up to IP66, which means it is dust-tight and can be sprayed with pressurized jets of water.

As for NEMA, we offer any type, starting with 1 and up to 13, including subtypes, such as 3R.

Our NEMA enclosures are protected against weather, corrosion, oil seepage, and much more.

Locks don’t compromise the protection your enclosures get because we engineer them safely.

How are KDM lockable enclosures different other lockable enclosures?

Lockable enclosures manufactured by KDM are compliant with RoHS, CE, IEC, and NEMA standards.

Introducing locks to an enclosure creates more risk of ingress – solid and liquid.

This is why it may more tricky to make these enclosures as protected from the elements as they should be.

But KDM overcomes this difficulty, offering some of the best enclosures for your business.
