40A rotary switch, direction of rotation changeover switch L-0-P, base rail mounting front grey knob black SK40-3.8368\BS03

Rotary direction switch – reliability and functionality in one device

This three-pole cam switch with a rated current of 40A is a solid solution for controlling electric motors and other devices requiring a change of rotation direction. Designed for mounting on a TH35 rail, it is distinguished by its high mechanical and electrical resistance, which guarantees long-lasting and trouble-free operation in demanding industrial conditions. Equipped with a black knob and a gray housing, it provides convenient operation and clear identification.

Construction and application

Cam switch SK40-3.8368\BS03 is a component dedicated to applications requiring frequent changes in the direction of rotation, e.g. in electric motor drives, construction machines, production lines or ventilation systems. The construction with three poles allows for controlling three-phase motors, and the 0 position provides additional safety by allowing complete disconnection of the power supply. Mounting on a TH35 rail facilitates quick assembly and disassembly, and solid screw connections guarantee a secure and safe connection of wires. The IP65 protection class protects against dust and moisture, making it an ideal solution for both indoor and open industrial spaces.
