IEC Standard GCK Low Voltage Withdrawable Switchgear

Product Overview & Application

The GCK low-voltage withdrawable switchgear is a comprehensive power distribution and motor control center designed to meet the requirements of modern industrial and commercial power systems. It is suitable for three-phase AC systems with a rated voltage of 380V/400V and a rated frequency of 50Hz/60Hz. The cabinet is widely applied in power plants, substations, metallurgical industries, petrochemicals, and large commercial buildings, serving as a critical hub for receiving and distributing electrical energy and controlling motors.

Key Features & Structural Design

1.Modular & Withdrawable Design: The cabinet is divided into functional compartments (circuit breaker room, busbar room, cable room, etc.). The drawer units are available in various standard module sizes, allowing for highly flexible circuit configurations and efficient space utilization.

2.High Safety & Mechanical Interlock: Equipped with a reliable mechanical interlocking mechanism, the drawer cannot be inserted or withdrawn when the circuit breaker is in the “ON” position. This ensures operators are protected from accidental contact with live parts. The fully enclosed structure provides a high level of safety.

3.Good Heat Dissipation: The top of the cabinet is equipped with ventilation holes and an optional exhaust fan system. The independent cable and busbar compartments create an effective air convection channel, reducing the temperature rise inside the cabinet.
