Cam switch, 0-1, 4-pole, for busbar, yellow-red knob SK125-4.4285\BS04

Cam disconnect switch for busbar – reliable disconnection in the installation

This 4-pole cam disconnect switch SK125-4.4285\BS04 is a solid solution for safely disconnecting circuits in electrical installations. Designed for mounting on a busbar, it provides convenient and reliable operation, and its construction guarantees high resistance to environmental conditions. Ideal for both professional installers and end-users looking for reliable protection.

Design and application

The cam disconnect switch SK125 BS is designed for mounting on a TS35 busbar, which simplifies its integration with existing infrastructure. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The rated current of 125A allows it to be used in circuits with high loads. The yellow-red knob makes it easy to identify and operate, and the switching angle of 45°-90° provides smooth and precise switching. The possibility of connecting wires with an 8mm eyelet terminal and M8 connection screws ensures easy and safe wire mounting.

• Versatile application: ideal for switchboards, control cabinets and other electrical installations requiring reliable circuit disconnection.
• Busbar mounting: quick and easy mounting on a standard TS35 busbar, minimizing installation time.
• High resistance: IP65 protection rating guarantees protection against dust and moisture, allowing it to be used in harsh environmental conditions.
• Safety of use: rated short-circuit current of 2.5kA provides effective protection against the effects of short circuits.
• Wide temperature range: the ability to operate in an ambient temperature from -40°C to +70°C makes it suitable for use in various climates.

Operating parameters and compliance with standards

The switch meets the requirements of EN 60947-1 and has a rated insulation voltage of 690V and a rated impulse withstand voltage of 8kV. The rated thermal current in air is 125A, ensuring safe operation even under high loads. The possibility of connecting from 1 to 7 segments increases application flexibility. The pollution degree according to EN 60947-1 is 3, which means that the device is adapted to work in environments with a moderate degree of pollution. The maximum tightening torque for wires is 12Nm – remember to tighten the connections properly to ensure safety and reliable operation.
