Cam switch, 0-1, 4-pole, for busbar, silver contact, black knob SK125-4.4285\BS03

Cam switch for busbar – reliable disconnection in the installation

This four-pole cam switch SK125-4.4285\BS03 is a solid solution for safe and convenient disconnection of circuits in electrical installations. Designed for mounting on a busbar, it provides quick and reliable contact, and its construction guarantees long-lasting and trouble-free operation. Ideal for both professional installers and end-users who value safety and functionality.

Design and application

The cam switch SK125-4.4285\BS03 is designed to operate in systems with a rated insulation voltage of 690V and a continuous rated current of up to 125A. Its robust construction allows it to withstand short-circuit currents up to 2.5kA, providing effective protection of the installation. Mounting on a busbar facilitates installation and allows for the creation of modular distribution systems. The silver label increases conductivity and corrosion resistance, and the black knob provides convenient operation.

• Application: Disconnecting electrical circuits in industrial installations and public buildings.

• Mounting: On a busbar (TS35), supports required for stable busbar mounting.

• Application: Main distribution boards, sub-distribution boards, motor control, circuit protection.

• Connection cables: Terminated with an 8mm diameter crimp terminal – facilitates quick connection of cables.

Key features and parameters

The switch is characterized by high reliability and durability confirmed by a number of technical parameters. The switching angle of 45°-90° ensures smooth and precise circuit switching. The IP65 protection class guarantees protection against dust and water jets, allowing operation in harsh environmental conditions. Thanks to the possibility of connecting from 1 to 7 segments, the switch is flexible and can be adapted to different installation needs.

• Number of poles: 4 – allows disconnection of all phases and the neutral conductor simultaneously.

• Continuous rated current (Iu): 125A – ensures safe operation under nominal load.

• Short-circuit current (Icw): 1.7kA – high resistance to momentary overloads.

• Rated insulation voltage (Ue): 690V – possibility of use in high-voltage installations.

• Protection class (IP): IP65 – protection against dust and splashing water.

• Operating temperature: -40°C to +70°C – possibility of use in a wide range of ambient temperatures.
