Circuit Breakers

Circuit breakers are designed to protect an electrical circuit from damage caused by an overload or short circuit. APL11-23478-1 is a type of circuit breaker which is used in general purpose applications. This article will discuss the application field and working principle of the circuit breaker.

Application Field of APL11-23478-1 Circuit Breakers

The APL11-23478-1 circuit breaker is typically used in industrial and commercial applications. It is suitable for use in applications where the voltage can be up to 600V AC and the amperage can be up to 400A. The circuit breaker is UL listed and CSA certified, so it meets all safety standards. In addition, it is highly reliable and provides protection against short circuits, overloads, and ground faults.

Working Principle of APL11-23478-1 Circuit Breakers

The APL11-23478-1 circuit breaker works on the principle of thermal overload protection. The circuit breaker is composed of a set of contacts, a bimetallic strip, and a trip mechanism. When an overload or short circuit occurs, the current will be too high, and this will cause the bimetallic strip to expand. As the bimetallic strip expands, it will push the trip mechanism which, in turn, will cause the contacts to open and break the circuit. The circuit breaker will then reset itself, and the current will be allowed to flow again.

Conclusion

The APL11-23478-1 circuit breaker is a reliable and safe device for protecting circuits from overloads and short circuits. It is suitable for use in industrial and commercial applications, up to a voltage of 600V AC and an amperage of 400A. It works on the principle of thermal overload protection which involves a bimetallic strip, trip mechanism, and contacts. It is an essential component for any electrical system, and should be chosen with care to ensure the safety of the circuit.
