Check the wiring, apply voltage or replace the coil. Replace the energy storage spring. Readjust spring force. Adjust the re-buckling surface to the specified value.

The company produces universal circuit breaker conventional phase sequence: N, A, B, C (front view, from left to right), such as the need to change the phase sequence can be customized with the company instructions.

There are two kinds, steel cable interlock and lever interlock, two interlocks by function (controller two circuit breakers, can only be combined into one) and three interlocks (control three circuit breakers, can be combined into two or one), only two interlocks below 1600 shell frame, DW45/HYW3-1000 only steel cable interlock. Lever interlocking is only applicable to the upper and lower stacking of circuit breakers, and the distance between two products is not more than 0.9 meters. The distance between two products of steel cable interlock is not more than 2 meters, and the bending degree of steel cable should not affect its function.

Readjust; replace the molded case circuit breaker.
