Circuit breaker has been widely used in modern electric circuits because of its advantages of simple structure, convenient installation and maintenance, safety and reliability, reliable performance, fast on-off switch, locking as required, long service life and so on. IEG112-29451-1-V is a circuit breaker specifically designed for industrial applications. This article mainly introduces the application field and working principle of IEG112-29451-1-V circuit breaker.

IEG112-29451-1-V circuit breaker is specifically designed for heavy industry and suitable for AC 50/60Hz rated voltage 500V, 400V, 380V, 220V and 110V long duration low current main circuit, branch circuit and starter. It is suitable for overload protection of electric motors, lighting and circuit control in three-phase four-wire systems or dual-voltage three-phase four-wire systems. It is also suitable for shorting protection of lighting and motor branches. This circuit breakers can be applied in Single-phase equipment, with current rating of 1A-40A. It can also be used in 3-phase applications with rated current of 1-3A.

In addition, IEG112-29451-1-V circuit breaker equipped with three poles standard manual reset, automatic reset, and a delay time adjustment knob for controlling cycle times, features a built-in arc capacitor and transient voltage suppressor protection. The built-in arc capacitor and transient voltage suppressor can protect the circuit from overvoltage or transient overvoltage, which can effectively reduce the failure rate of the circuit breaker.

The working principle of IEG112-29451-1-V circuit breaker is simple. When the circuit breaker is opened, the contact will separate, cutting off the power supply of the circuit. When the circuit overload occurs, the built-in thermal element will heat, the temperature will rise to a certain critical value, and then the overtemperature protector will pull down the operating lever, the contact will concomitantly separate, the power supply of the circuit will be cut off, and the circuit breaker will be tripped out. After the overcurrent disappears, the operating lever will return to its original position, the contact will concomitantly return to its original position, the power supply of the circuit will be restored, and the circuit breaker will be closed.

In summary, IEG112-29451-1-V circuit breaker is a special circuit breaker specially developed for heavy industry. Its application field include AC 50/60Hz rated voltage 500V, 400V, 380V, 220V and 110V long duration low current main circuit, branch circuit and starter. It is an ideal product for protecting circuits from overload and short circuit. The working principle is simple and easy to understand.}
