Overview
KBO-12CKBOD-M25/32C control and protection switch electrical equipment is mainly used for AC 50HZ (60HZ), rated power operating voltage of 690V, rated current of 100A in power systems under normal conditions for connection, loading, and disconnection, as well as specified abnormal conditions for current (such as short-circuit current).
Product Details
1、 Product Overview
The KBO-12C KBOD-M25/32C control and protection switch adopts a new energy-saving technology for control and protection. The electromagnetic system of the switch adopts a switch cabinet suction current circuit, and the switch electromagnetic system adopts AC starting. The DC suction working mode is controlled by a microcontroller. The iron core loss and short-circuit ring loss of the switch electromagnetic system are minimized, and the copper loss of the coil is only about 4% of the original, which greatly saves energy and reduces the temperature noise of the switch electromagnetic system.
