OUVT-X1 Over-under Voltage Release

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

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.
