GCK(L) AC low-voltage withdrawable switchgear is a power distribution and asynchronous motor control equipment of AC 380V system (hereinafter referred to as device). It is suitable for the centralized control of electric motors in the power distribution of factories, mines and buildings, as well as metallurgical, chemical, and light industrial production lines. It can also be combined with a program controller and a microprocessor to form an automatic control system for power supply and distribution.
The main technical parameters
Structure feature function
★GCK(L) AC low-voltage withdrawable switchgear is a compartmentalized device, which adopts a modular structure design. From the structure, it can be divided into two parts: the cabinet and the functional unit; this device has an incoming cabinet and a functional unit cabinet Two types, the protection level of the shell meets the requirements of JJIP30.
★The plug-in circuit breaker is selected for the unit of the incoming cabinet, which has the characteristics of advanced structure, high dielectric capacity and strong interchangeability; especially the user can set its rated current and transient current as required, and with loss of voltage, Signal and locking device for over current and short circuit. The bus tie switch also adopts the same functional unit as the incoming cabinet, which can be made into automatic or manual input according to user requirements.
★The functional unit has three positions of "separation", "test" and "connection" in the unit isolation room.
