Cam switch disconnector 40A, Isolator 0-1 (3-pole), in OB2 enclosure with lockable front ŁK40-2.8211\OB2Z

Universal cam switch for demanding applications

This three-pole cam switch with a rated current of 40A is a reliable solution for manual switching of electrical circuits. Designed for both industrial and building installations, it provides safe and convenient operation. Equipped with a "0" position, it allows for complete disconnection of the circuit, which is crucial during maintenance or repair.

Solid construction and high protection

The switch enclosed in a durable OB2 housing made of plastic guarantees resistance to mechanical damage and external factors. The IP65 protection class provides effective protection against dust and water jets, allowing its use in harsh environmental conditions. Screw connection of the main contacts ensures a secure and durable connection of the wires.
