GYM9 Auxiliaries

The electrical accessories of this series of circuit breakers are the auxiliary functional components specially designed by our company for GYM9 series circuit breakers. In the light circuit, household and building, different electrical accessories and GYM9 series circuit breakers can be selected according to the need, which can realize remote control, circuit breaker status indication, alarm signal, under-voltage and over-voltage protection function.

When it gets signal, it triggers the circuit breaker to trip. When power voltage lowers( 35%~70%Un), it makes circuit breaker trip; When power is not supplied normally, it prevents circuit breaker from reconnecting to the circuit.


Monitor voltage between phase line and neutral line. When voltage rises( for example, neutral line is broken) , it triggers circuit breaker to trip. It has function of over-voltage release, and function of making circuit breaker trip when power voltage lowers.
0.2 S time delay prevents the temporary lowering of voltage from causing mistrip. rated tripping voltage range: 280vac±5%. Rated tripping voltage range: 280vac±5%.

Rated under-voltage tripping range: 55~160v.


Distant control can achieve emergency breaking. Prevent machine from restarting without control signal, ensuring safety. Prevent over-voltage from damaging circuit and equipment. Prevent over-voltage and under-voltage from damaging circuit and equipment.
