OUVT-1 Over/under voltage release

To be assembled with circuit breaker to achieve over/under voltage protection.

Product Information

Rated operation voltage Ue: AC 240V, 50Hz; Overvoltage operation setting value Uvo: 280V; Rated insulation voltage Ui: 500V; Tripping characteristics: the release is assembled with NXB-63 series circuit breaker. When the applied voltage is reduced to 35%Ue or increased to 95% ~ 105% of the over-voltage setting value, the release should drive the circuit breaker to act. When the applied voltage is below 35%Ue or above 105% of the over-voltage setting value, the release should be able to prevent the circuit breaker from closing. When the supply voltage is above 85% Ue and below 95% of over-voltage setting value, the circuit breaker should be able to close normally. The upper limit of the applied voltage should be less than 110% over-voltage operation setting value. Mechanical and electrical life: the mechanical and electrical life after the release is assembled with the circuit breaker should be ≥ 4000 cycles, of which, 500 cycles for over-voltage trip and under-voltage trip each, and 3000 cycles for the open/close of the circuit breaker.
