Electrical Enclosure Latches: Ultimate FAQ Guide

What is Electrical Enclosure Latches?

Electrical enclosure latches are mechanisms that close electrical cabinets’ doors. By slightly pushing the door, electrical enclosure latches will hold the door in place (closed), thou, they do not lock it.

Electrical enclosure latches come in many designs – from spring-loaded, one piece to complex options.

Compression Latch and Quarter Turn Latch; How do they Compare?

Most electrical enclosure latches are quarter turn.

They offer simple locking mechanism, tamper-resistant and a certain degree of compression.

You’ll simply turn it once to lock the electrical enclosure.

Compression is an additional feature which some electrical enclosures come with to meet certain industry standards such as IP 65.

That’s why you will come across quarter-turn compression latches.

Compression latches are common in electrical cabinets that require tight pressure sealing such as Cajas eléctricas para exteriores o Cajas eléctricas resistentes a la intemperie.

With compression latches, rotating the insert or handle will move the cam to a locking position. Depending on the design of the compression latch:

i. You can continue to rotate the handle or insert to achieve compression (it is more of a screw mechanism)

II. Press to achieve compression

iii. Turn once to achieve compression

Whichever the case, the action will pull the electrical enclosure door to about 6mm, thereby compressing the gasket. They are common in IP 65 Enclosures.

Between 3 Point Turn Latch System and Quarter Turn Latch, Which One is Safe for Electrical Cabinet?

3 point turn latch system is safer and more secure than quarter-turn latch systems.

However, a 3 point turn latch system, also called multipoint lock, is more expensive than a quarter-turn latch.

Moreover, the 3 point turn latch systems are suitable for Cajas eléctricas para exteriores such as those in street light or telecommunication cables.

Such systems are installed in remote or isolated areas, thus requires a safe locking mechanism that can prevent intrusion.

Outdoor electrical enclosure

Should you Choose Keyed Alike or Master Keyed Electrical Panel Locks?

Keyed alike is a situation where you will open all electrical panel locks using one key.

You can use this for electrical enclosures within the same section to avoid having many different keys.

However, in situations where a more secure system is a priority, go for keyed different electrical panel locks.

When it comes to master keyed electrical panel locks, you will have one key that can open all electrical enclosures.

However, each electrical enclosure will have its unique key for the locks.

Electrical panel lock system

Is There a Difference Between Electrical Enclosure Latches and Locks?

Latches provide a mechanism for closing or fastening electrical enclosures, without necessarily locking it.

On the other hand, electrical enclosure locks prevent anyone who does not have the key from opening the door.

For a more secure system, you should go for electrical enclosures with both latching and door lock systems.

How Does Electrical Enclosure Latches Work?

Electrical enclosure latches are activated by closing panel doors.

Once they are activated, they will hold the electrical enclosure door in a closed position.

The closing mechanism will depend on the design of the electrical enclosure latch.

For instance, some will require that you manually turn the knob or handle to keep it closed.

Whereas the spring-loaded enclosure door latches will automatically close.

They depend on the spring compression force.

Are there Additional Features for Electrical Enclosure Locking Systems?

Yes, a good electrical enclosure locking system should guarantee the safety of all electrical equipment and related accessories.

Depending on the level of security and safety you desire, an electrical enclosure locking system may have these additional features:

• Biometrics door access system with a fingerprint scanner or eye scanners
• Both latching and locking mechanisms combined
• Same or different keys for the electrical enclosure locking system
• Tamperproof mechanism
• Alarm system
• Integrated cameras
• Remote locking and unlocking mechanism

Note: All the additional features on the electrical enclosure locking systems provide additional safety and security, thou at an extra cost.

What Types of Electrical Enclosure Latches Does KDM Offer?

KDM lockable electrical enclosures feature standard and customized electrical enclosure latches.

Available options include:

• Spring-loaded electrical enclosure latches
• Quarter turn electrical enclosure latches
• Compression latching system for electrical enclosures
• Quarter turn latches for electrical cabinet
• IP and NEMA rated electrical enclosure latches

What is IP 65 Rated Electrical Enclosure Door Lock?

It is a door lock that will protect an enclosure from powerful or high-speed water jets, dust, and oil.

Such enclosures are suitable for outdoor environments.

You will find IP 65 door locks on NEMA 4 Enclosures y NEMA 4X Enclosures.

Cajas NEMA

A good example of IP 65 rated door lock is the compression latch and lock system.

They tightly lock and seal the door, by compressing the gasket, thereby providing the best protection.

What Does IP 55 Rating Mean for Electrical Enclosure Latches?

IP 55 rated electrical enclosure latches guarantee limited protection from oil, dust, low-pressure water jet, dirt and non-corrosive material.

Remember, when it comes to IP enclosure ratings, you need to focus on every aspect that cannot compromise the set standards.

This includes electrical enclosure hinges, latches, ventilation systems, etc.

You will find electrical enclosure latches that meet the IP 55 rating in NEMA 3 enclosures:

• NEMA 3X enclosure
• NEMA 3S enclosure
• NEMA 3SX enclosure

Do NEMA Rating Cover Electrical Enclosure Locks and Latches?

Sí.

When it comes to NEMA enclosure rating, classification takes into account every aspect of the electrical enclosure; from hinges, handles, electrical enclosure locks and latches, amongst others.

For example, NEMA 4 Enclosure and NEMA 4X must protect its contents from high-speed water jets (even from nozzles) and dust.

In such cases, you need a compression latch.

Also, NEMA 3 Enclosure and NEMA 3X Enclosures require electrical enclosure locks and latches that can protect it from limited dust and low-pressure water.

Which Material is Best for Electrical Enclosure Locks and Latches?

The type of electrical enclosure locks and latches material will depend on the design of electrical cabinet material.

Besides, the locks and latches have different parts that are made from a range of materials.

Some of the most common materials include:

• Acero carbono
• Acero inoxidable
• Aluminium
• Brass
• Thermosetting plastic or any other durable plastic such as polycarbonate
• Galvanized steel, etc.

Are There Design Options for Enclosure Handles?

Sí.

First, you should consider the type of material where you can choose from either plastic or metallic enclosure handles.

Door handles

Then you can go ahead to choose different designs of enclosure handles such as:

• T-door handle with a lock
• Non-locking or key-locking handle
• Lever handle
• Knob handle
• Two-piece vs. one piece
• Pulled handled, etc.

The choice of the enclosure handle will depend on your unique designs.

What is the Right Position for Electrical Enclosure Door Handle?

The electrical enclosure door handle should be on the opposite side from hinges.

Then, it should be centrally positioned like this:

Centrally positioning of lock and handle

This way, it is easier to open, close and lock the electrical enclosure.

Depending on the design of the electrical enclosure and function of the handle (remember some come with slots for keys), you can have them in:

i. Vertical position

II. Horizontal position

iii. Slanting position

Are There Tamper Resistant Enclosure Latches?

Sí.

In fact, tamper-resistant electrical enclosures are the best for most outdoor applications such as fiber optic enclosure.

Normally, tamper-resistant enclosure latches may have unique features such as screws, dual brackets, or other additional locking mechanisms.

Apart from Electrical Enclosure Latches; What else Guarantees Electrical Cabinet Safety?

i. An electrical enclosure should have a high quality, unique and reliable locking mechanism. If possible, incorporating additional technologies such as alarms and biometrics will help.

II. Electrical enclosure hinges should be inside the enclosure. It is a sure way of protecting hinges from possible tampering.

iii. Avoid protruding electrical locking and latching mechanism. You should go for recessed electrical enclosures.

iv. Adopt combination locks for the enclosure.

a. Avoid standard keys or Keyed alike for sensitive electronic enclosures that require privacy and more security.
