Main parts:
1. Intelligent Controller with long time tripping, short time tripping and instaneous tripping
Rated voltage: 230V AC or 400V AC or 220V DC
2. UVT (undervoltage release/ undervoltage tripping device). There are instantaneous trip and delayed trip. Delay time is 1-20s, adjustable. Within halh of delay time, the voltage of main circuit recovers to 85% of rated voltage or above, the Circuit breaker won’t be open.
Reated Voltage (Ue): 400V AC or 230V AC
Tripping violtage: from 35 percent to 70 percent of Ue
Power consumption: 12VA
3. Shunt release (shunt tripping device)
Reated Voltage (Ue): 400V AC or 230V AC or 220V DC
Tripping voltage: from 70 percent to 110 percent of Ue
Break time: less than 30ms
