OVT-X1 Overvoltage release

Overvoltage release

Main function: assembled with circuit breaker to achieve overvoltage protection
Rated operating voltage Ue: AC230V 50Hz or 60Hz;
Rated insulation voltage Ui: 500V;
Overvoltage action setting value Uo: 280 (1 ± 5%) V;
Tripper action characteristics: When the main circuit voltage is 230 (1 ± 5%) V, the trip unit should be able to keep the circuit breaker working for a long time.
When the main circuit voltage rises to 280 (1 ± 5%) V, the trip unit combined with the NXB-63 series circuit breaker should be
Action to disconnect the NXB-63 circuit breaker.
Mechanical durability: The mechanical durability of the trip unit is not less than 4000 operating cycles.
