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. |
||
Application |
||||
| 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. | |
