Cam switch 40A, 1-0-2 Disconnector (6-pole), long black knob ŁK40-6.8380\P09

Rotary cam switch – reliable circuit switching

This six-pole rotary cam switch, catalog number ŁK40-6.8380\P09, is a robust solution for frequent switching of electrical circuits. Designed for both professional and demanding end-user applications, it combines durability, safety and ease of use. This model is characterized by a 1-0-2 disconnector design, which means the ability to choose between three positions: open (0), closed (1) and a second position (2). The long black knob provides a secure grip and precise operation.

Construction and application

The ŁK40 rotary cam switch is designed for indirect mounting and is made of high-quality plastic, which ensures its mechanical strength and resistance to environmental conditions. The IP65 protection class guarantees protection against dust and water jets, making it ideal for use inside buildings and in environments exposed to moisture. The rated operating power for AC-3 is 20 kW at 400 V, making it suitable for controlling various electrical loads.
