|Rated operating voltage||
AC 240V; 50Hz
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. Whenthe applied voltage is reduced to 35%Ue or increased to 95% ~105% of the over-voltagesetting 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 releaseshould be able to prevent the circuit breaker from closing. When the supply voltage isabove 85% Ue and below 95% of over-voltage setting value, the circuit breaker should beable 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 isassembled with the circuit breaker should be ≥ 4000 cycles, of which, 500 cycles forover-voltage trip and under-voltage trip each, and 3000 cycles for the open/close of thecircuit breaker.
