Cam switch 40A, 1-0-2 switch (4-pole), base mounting rail front grey knob black SK40-4.8396\BS03

Universal cam switch for safe circuit switching

This 4-pole cam switch with a rated current of 40A is a reliable solution for frequent switching of electrical circuits. The 1-0-2 design allows you to choose between two circuits, and the "0" position ensures safe disconnection of the power supply. It is ideal for both industrial installations and public buildings where high reliability and durability are required. Rail mounting allows for quick and easy integration with existing infrastructure.

Construction and application

The switch is designed for mounting on a TH35 rail, which facilitates its installation in electrical switchboards. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The black knob allows for convenient and intuitive control, and the high degree of protection IP65 guarantees safe use even in harsh environmental conditions. Designed for applications requiring frequent circuit switching, e.g. when changing the power source, servicing machines or in automation systems.

Key features and benefits

• High reliability: Continuous rated current of 40A and high surge current resistance ensure stable operation even under heavy loads.
