The SIWOG4 series isolation switch is developed and designed by Shenyang Siwo Electric Appliance Co., Ltd. using a modular concept. The switch body adopts a specialized module assembly and new appearance design, reducing the exposed metal parts of the switch body and improving the safe operation performance of the switch; Modular design facilitates the disassembly and combination of switches, suitable for different usage requirements and occasions; Adopting two operation methods: handle operation mechanism and electric energy storage, it is convenient for reliable operation of the switch.
The SIWOG4 series isolation switches are suitable for low-voltage distribution networks with rated working voltages of DC1000V, DC1500V, and rated working currents of 200A~2500A. They can meet the corresponding rated currents for on-load making and breaking, and can also withstand overload currents in the line for a short period of time.
The SIWOG4 series isolation switch can be used as the main power switch, isolation maintenance switch, and emergency stop switch in the new energy industry, wind and solar storage systems, power, rail transit, data centers, etc.

Safe isolation
1. Visualization window: The opening and closing positions of the moving contacts are clearly visible, providing a higher level of safety assurance.
2. "0" position padlock: When in the zero position, the handle can be padlocked to prevent misoperation.
3. Rotating double break point contact structure: ensures a safe distance for isolation and meets the requirements of reliable isolation.
4. Double spring operating mechanism: Double spring energy storage mechanism, achieving fast connection and disconnection, with conversion effect independent of operating speed.
Reliable application
1. It can be operated with load.
2. Modular structural design: The product is composed of unipolar modules and operating mechanism modules, improving the utilization of installation space.
3. Operation mode: Provide multiple operation modes, including front operation, inside cabinet operation, outside cabinet operation, etc.
4. Expansion attachment: Auxiliary contact module.
