China GCS Low Voltage Withdrawable Switchgear - High Performance from Trusted Suppliers and Factory
Model meaning
Conditions of use
≤ 2000m
Upper limit: +40℃, lower limit: -5℃. The average temperature within 24 hours should not exceed +35℃. Minimum storage/transportation temperature: -30℃.
Does not exceed 50% at +40℃. Higher relative humidity is allowable at lower temperatures (e.g. 90% at +20℃). Occasional condensation due to temperature changes should be considered.
Inclination of the vertical plane should not exceed 5°. Install in a place free from severe vibration, impact, or medium sufficient to corrode electrical components.
Product characteristics
Fully assembled combination structure. Side installation holes of 20mm and 100mm modules (φ 9.2mm) make internal installation flexible and convenient.
Divided into functional unit room, busbar room, and cable room. Areas are strictly separated by grounded metal plates or flame-retardant plastic plates to ensure safety.
All internal structural components are galvanized and passivated. Panels are made of high-quality cold-rolled steel plates processed by CNC, with acid washing, phosphating, and electrostatic spraying.
Five draw-out positions with mechanical interlocks. Units can only be moved when the switch is open. Operating handles can be padlocked in the open position.
The horizontal main busbar is flatly arranged at the back of the cabinet to resist high short-circuit power. Vertical busbars are assembled in insulated functional boards to prevent phase discharge. Cable compartments allow convenient entry and exit from both top and bottom.

Switchgear and draw-out types
According to the purpose, it can be classified into: incoming cabinet, bus-tie cabinet, feeder cabinet (motor centralized control cabinet, lighting distribution cabinet), and reactive power compensation cabinet.
According to the incoming method, it can be classified into four types: upper incoming & upper outgoing, upper incoming & lower outgoing, lower incoming & upper outgoing, and lower incoming & lower outgoing.
There are five height specifications for the draw-out units, based on a basic unit height of 160mm: 1/2 unit, 1 unit, 3/2 unit, 2 unit, and 3 unit. The maximum draw-out circuit current is 400A or below.
