To be assembled with the circuit breaker to achieve overvoltage protection
Rated operation voltage Ue: AC 240V 50Hz (or 60Hz).
Rated insulation voltage Ui: 500V.
Overvoltage setting value Uvo: 280V.
Release action characteristics: when the main circuit voltage is in the range of (85% ~ 110%) Ue, the release shall be able to keep the circuit breaker to work reliably for long term. When the main circuit voltage is increased to 280 (1 ± 5%) V, the release assembled with NXB-63 series circuit breaker should act and trip open NXB-63 circuit breaker. Mechanical and electrical life: the mechanical and electrical life of release is ≥4000 operation cycles
