Meet the performance level requirements of system voltage, current, frequency and breaking capacity; breaking capacity: requirement ≥35kA;

Ics=100%Icu. The protection level is greater than or equal to IP40;

Provide electronic trip device or thermal magnetic trip device. The electronic trip unit provides three-stage protection (long time delay, short time delay, instantaneous action), of which the long time delay is adjustable from 0.4 to 1Ir, the short time delay is adjustable from 1.5 to 10Ir, and greater than 11In is instantaneous protection; thermal magnetic trip The device provides two-stage protection (long delay, instantaneous action), of which the long delay is 0.8-1Ir adjustable, and the short-circuit instantaneous value is a fixed value or 5-10Ir adjustable depending on the set value.

The shell structure is a modular structure design, easy to install and disassemble, and various accessories (such as shunt release, auxiliary contact, alarm contact) can be added without removing the molded case circuit breaker without changing the circuit breaker Device structure and emergency power supply cabinet (EPS).
