Introduction

Circuit breakers are important components of electrical and electronic systems. They protect the system from damage due to short circuit, over current and overloads. The 412-K54-LN2-5A is a type of circuit breaker designed for medium voltage applications.

Application Field

The 412-K54-LN2-5A is a three-pole circuit breaker suitable for low, medium and high voltage applications. It is specifically designed to provide overload and short circuit protection in medium voltage systems. It is suitable for use in residential, commercial and industrial applications. The circuit breaker features an adjustable current rating of up to 1000A and can handle up to 15kV.

Working Principle

The 412-K54-LN2-5A circuit breaker uses a two-step trip mechanism to protect the circuits from damage. The first stage is the thermal protection stage, which works by sensing the current flow in the circuit. When the current level exceeds the preset limit for a certain time, the breaker trips and disconnects the circuit.The second stage is the magnetic protection stage, which works by sensing the magnetic force generated by the current flow in the circuit. When the magnetic force exceeds the preset limit, the breaker trips and disconnects the circuit.

Conclusion

The 412-K54-LN2-5A is a three-pole circuit breaker suitable for low, medium and high voltage applications. It is specifically designed to provide overload and short circuit protection in medium voltage systems. The circuit breaker features an adjustable current rating of up to 1000A and can handle up to 15kV. It uses a two-step trip mechanism to provide effective protection from short circuit, over current and overloads.
