CPS is "control and protection switchgear". It is mainly used for AC 50Hz (60Hz), rated working voltage to 690V, rated working current 1A to 125A, controller setting current 0.4 A to 125A, and control motor power 0.12 kW to 55kW. In circuits, it can turn on, carry and break the current under normal conditions (including specified overload conditions), and can also turn on, carry for a certain time and break the current under specified abnormal conditions (such as short circuit).
