IEC 60934 standard specifies the model designations and characteristics of a circuit breaker in the form of IEGN111-1REC4-72-15.0. This number refers to a 1-pole, 4-pole, 72A rated and 15kA breaking capacity circuit breaker. This type of circuit breaker is widely used since it has a wide range of application fields and it can work at maximum AC690V and DC400V.

The application field of IEGN111-1REC4-72-15.0 circuit breaker includes but not limited to industrial, commercial and residential building. It is widely used in places that require high safety such as electrical systems, machinery, transportation vehicles, etc. It can also be used for electronic equipment, control systems, protecting personnel and facilities from dangers.

The working principle of IEGN111-1REC4-72-15.0 circuit breaker is pretty complicated. In short, it works by detecting any disruption in the electrical current. When a high current in the circuit exceeds the rated capacity, the circuit breaker senses the change in current and trips immediately, interrupting the circuit and preventing equipment damage and injury. During the operation, the circuit breaker has two separated contacts connected to a solenoid. The solenoid deforms the contacts depending on the current, closing or opening the circuit. This feature further increases the safety of circuit breakers.

The IEGN111-1REC4-72-15.0 circuit breaker has an adjustable trip setting which is used to set the maximum current rating and determine when the breaker will trip. It is important to know the trip settings as an overload or short circuit could damage expensive equipment or cause fires if the breaker is set to trip too late. Therefore, it is necessary to check the trip setting and maintain it regularly.

All in all, IEGN111-1REC4-72-15.0 circuit breaker is a very useful device for safety protection, with a wide range of application fields and principle of operation. It is important to set the trip setting correctly to ensure the equipment and personnel safety. Overall, this type of circuit breaker is a reliable and cost effective solution for electrical system protection.
