Main function: assembled with circuit breaker to achieve undervoltage protection
Rated operating voltage Ue: AC 230V, 50Hz;
Rated insulation voltage Ui 500V;
Undervoltage action setting: (35% ~ 70%) Ue;
Operating characteristics: external voltage ≤ 35% Ue, the product should prevent the circuit breaker from closing; 35% Ue ≤ external voltage ≤ 70% Ue,
The product moves and drives the circuit breaker to open; the applied voltage ≥85%Ue, the product should be able to close. The applied voltage value should not exceed
110% Ue.
Mechanical durability: The mechanical durability of the trip unit is not less than 4000 operating cycles.
