Cam switch 16A, 1-0-2 switch (3-pole), base mounting rail front grey knob black SK16-3.8380\BS03

Universal cam switch for busbar systems

This three-pole cam switch SK16-3.8380\BS03 is a reliable solution for connecting and disconnecting electrical circuits. Designed for mounting on base rails, it provides convenient installation and safe operation. The construction with a gray body and black knob facilitates identification and operation. Ideal for both professional installers and end-users where reliable operation and durability are required.

Construction and application

The SK series cam switch is an element used for manual switching of electrical circuits. The version with a 1-0-2 disconnector allows you to choose between two positions, which finds application in control systems, power distribution boards, and applications requiring flexible load switching. Mounting on a base rail ensures stability and easy integration with existing electrical infrastructure. Particularly useful in situations where visual control of the circuit status is needed, as well as the ability to quickly disconnect the power for service or emergency purposes.
