Cam switch 40A, 1-0-2 switch (3-pole), panel mounting front grey knob black ŁK40-3.8380\P03

Cam switch – reliable circuit switching

This three-pole cam switch with a rated current of 40A is a solid solution for manual switching of electrical circuits on and off. It finds application in installations where reliability and manual control are required, e.g. when switching on motors, transformers or other electrical devices. The design with a 0 position provides additional safety and convenience.

Construction and application

The switch is designed for mounting on a panel or in an enclosure, which facilitates its integration with existing installations. Made of durable plastic, it ensures durability and resistance to mechanical damage. Designed to operate in a wide temperature range, from -40°C to +70°C, making it suitable for use in harsh environmental conditions. The connection of the main contacts is made using screw connections, which guarantees a secure and stable connection of wires with a cross-section of 4-10 mm². The IP65 protection class (front side) provides protection against dust and water jets.
