1G125UM

Circuit Breakers

As one of the most important electrical and mechanical control systems, circuit breakers play an essential role in all kinds of working conditions and environments. The 1G125UM circuit breaker is not an exception.

Application Field

The 1G125UM circuit breaker is an overcurrent protective device designed for the protection and control of circuit for three-phase AC4 motors. The rated running current of the 1G125UM circuit breaker is 125A, and with a short-circuit breaking capacity of 9.6kA. Therefore, it is widely used in the main power supply system in industry, agriculture and other fields.

Working Principle

The 1G125UM circuit breaker relies on spring stored energy to particularly contact with each other automatically against to overcurrent, short-circuits and other malfunction. When an overload, short-circuit, or other fault occurs in the circuit, the overcurrent will cause the moving contacts to be rapidly moved to the open circuit position by the action of the tripping device, thus achieving the purpose of disconnecting the circuit and protecting equipment and personnel safety. When the overcurrent disappears, the moving contact can automatically reset the device under the pressure of the mechanical resetting spring, thus achieving the purpose of automatically resetting the protection device.

Conclusion

The 1G125UM circuit breaker is a powerful and reliable overcurrent protective device which can be used in many different working conditions and environments. Therefore, it is widely used in the main power supply system of industrial, agricultural and other fields, providing reliable protection and control of the circuits.
