| DZ47G |
Overvoltage Circuit Breaker |
When the voltage rises to 270V±5%, the circuit breaker is tripped to realize the overvoltage protection of the circuit |
|
| DZ47Q |
Undervoltage Circuit Breaker |
When the voltage drops between 170V±5%, the circuit breaker will be tripped to realize the undervoltage protection of the circuit |
|
| DZ47GQ |
Overvoltage and undervoltage circuit breakers |
When the 220V rated power supply voltage rises to 270V±5% or drops to 170V±5%, the circuit breaker is tripped to achieve line protection. |
