A DIN rail DC circuit breaker is designed for mounting on a DIN rail in DC systems. The DIN rail is a specialized railing system used for installing electrical devices on distribution boards and control panels.

Features
Some key features of DIN rail DC circuit breakers are as follows:
- They have brackets or mounting clips allowing simple installation on the DIN rail.
- Fabricated with a voltage rating defining the maximum voltage allowed such as 12V, 24V, and 48V.
- Can be built with remote functionality such as shunt trips or voltage-dependent tripping.
- Feature current ratings suited for different application needs such as 1A, 2A, 5A, 10A, and 20A define the maximum allowed current.
- Possess protection features from electrical faults such as overloads and short circuits by utilizing thermal or magnetic trip mechanisms.
- The tripping characteristics of DIN rail DC circuit breakers dictate the response time to conditions of overload and short-circuit.
Application
Some common areas of application of the DIN rail DC circuit breakers include:
- Automation systems and distribution boards aiding motor control and PLCs utilize DIN rail DC circuit breakers.
- DC-powered distribution units for routers and servers in telecommunication systems can be configured with these circuit breakers.
- Off-grid power systems for recreational vehicles, water vessels, and DC-powered homes.
