GCK type low-voltage withdraw able switch gear (hereinafter referred to as switch gear) is suitable for control and distribution systems with AC 50 (60) Hz and rated working voltage of 400V and below. It consists of two parts: the power distribution center (PC) cabinet and the motor control center (MCC). As a power distribution motor control and lighting distribution equipment. The cabinet is made of 8MF steel combination splicing, and each functional unit is relatively independent. The propulsion mechanism adopts a lever propulsion mechanism to ensure that the same units can be interchanged, providing power supply reliability.
