40A reversing starter, direction of rotation changeover switch L-0-P, base mounting rail front closure black SK40-3.8368\BS07

Cam switch for demanding applications

This cam switch with a rated current of 40A is a reliable solution for frequent switching of electrical circuits. Designed for both professional and end-user applications, it ensures safe and efficient operation in various conditions. The housing made of plastic and the high degree of protection IP65 guarantee durability and resistance to external factors. Model SK40-3.8368\BS07 is particularly recommended for applications requiring a change in the direction of rotation of electric motors.

Construction and application

The cam switch SK40 is a three-pole device with a "0" position, enabling precise control of electrical circuits. Designed for mounting on a base-rail with a lockable front (BS07), which ensures easy installation and removal. It finds application in switchboards, control cabinets, and in industrial machines and equipment where manual circuit switching is necessary. The knob as an actuator provides convenient operation, and the solid construction guarantees long-term operation.

Key features and benefits
