GCS Low Voltage Withdrawable Switchgear - High-Performance Electrical Solutions from China Suppliers & Factory
≤ 2000m
Upper limit: +40℃, Lower limit: -5℃. 24-hour average should not exceed +35℃. Minimum storage/transportation temperature: -30℃.
≤50% at +40℃; higher relative humidity allowable at lower temperatures (e.g., 90% at +20℃). Occasional condensation due to temperature changes must be considered.
Vertical plane inclination not exceeding 5°. Free from severe vibration, impact, and corrosive medium affecting electrical components.
Note: When the above normal service conditions cannot meet the usage requirements, negotiation between the user and the manufacturer is required.
Strong Commonality of Structure and Flexible Assembly: The switchgear is a fully assembled combination structure, featuring installation holes of 20mm and 100mm modules on the side (diameter φ 9.2mm), making internal installation flexible and convenient.
Modular Compartment Division: Compartments are strictly divided into functional unit room, busbar room, and cable room. Areas are separated by continuously grounded metal plates or flame-retardant plastic plates to ensure safety and prevent accident spreading.
Corrosion-Resistant Surface Treatment: All internal structural components are galvanized and passivated. Panels made of high-quality CNC cold-rolled steel undergo acid washing, phosphating, and electrostatic spraying for superior wear/corrosion resistance and grounding continuity.
Multi-Position Draw-Out Unit & Safety Interlocks: Features connection, test, disconnection, draw-out, and isolation positions. Equipped with mechanical interlocks (pull/insert only in open state; padlockable). Interchangeable units support up to 36 auxiliary contact pairs for remote monitoring and automation.
Optimized Busbar & Cabling System: Horizontal main busbar is flat-arranged at the back for high short-circuit strength. Vertical busbars are enclosed in insulated functional boards to prevent arcing flashover. Cable compartments facilitate easy top and bottom entry/exit.

Note: The above are recommended sizes. Users with special size requirements can negotiate with our company.
The rated insulation voltage is AC 660V with a rated working voltage of AC 380V (AC 400V). The enclosure features an IP40 protection rating.
The rated current for the horizontal busbar is ≤4000A (peak withstand up to 176kA, short-time withstand up to 80kA/1s), and the vertical busbar is rated at 1000A (peak withstand 105kA, short-time withstand 50kA/1s).
Each draw-out unit is equipped with a mechanical interlock device ensuring it can only be inserted or pulled out when the switch is in the open state. Furthermore, operating handles can be padlocked in the open position to prevent unauthorized operations.
Draw-out units are structured based on a modular 160mm base height and come in five sizes: 1/2 unit, 1 unit, 3/2 unit, 2 unit, and 3 unit, supporting current loads up to 400A.
Standard dimensions are 2200mm high, 800/1000mm deep, and 600/800/1000mm wide. Users with non-standard service conditions or special dimension requirements can negotiate customized options directly with the manufacturer.
