Circuit Breakers

A circuit breaker, also known as an electrical switch, is an essential and important component in electrical safety and reliability. The IULN111-1REC4-61-30.0-E is a particular type of circuit breaker, designed for use in industrial and electrical applications.

Application Field

The IULN111-1REC4-61-30.0-E is a medium duty 630A/480VAC one-pole circuit breaker, designed for use in industrial electrical power systems. It can be used to protect downstream circuits from short circuits and ground faults, or to provide manual or automatic switching in case of overloading. The IULN111-1REC4-61-30.0-E can be used to protect motors, lights and other electrical equipment.

Working Principle

The IULN111-1REC4-61-30.0-E circuit breaker consists of two parts: a main part and a trip unit. The main part consists of an insulated handle connected to an electromechanical spring-loaded mechanism. The trip unit consists of an electromagnet, a bi-metallic strip and a thermal overload sensor. When the current in a circuit exceeds the pre-set level, the overload sensor activates the trip unit. The electromagnet then pulls the bi-metallic strip, causing it to bend rapidly. This sudden bending of the bi-metallic strip supplies force which, in turn, allows the spring-loaded mechanism to trip the circuit breaker. Thus, the IULN111-1REC4-61-30.0-E circuit breaker is able to protect a circuit from current overloads.

It is important to note that the IULN111-1REC4-61-30.0-E circuit breaker is designed to operate in emergency situations only. Pay attention to the surrounding circumstances when using it, and use it with caution.
