Cam switch disconnector 63A, 0-1 switch (4-pole), in OB4 housing with lockable front ŁK63-2.8210\OB4Z

Universal cam switch for various applications

This four-pole cam switch with a rated current of 63A is a versatile device designed for switching electrical circuits on and off. The design allows it to function as a 0-1 disconnector, meaning it allows for complete disconnection of the load. Made of durable plastic, combined with a lockable front cover, ensures reliable operation and safety.

Construction and application

A cam switch is an element used to manually switch electrical circuits. This model uses a knob as the actuating element, providing convenient and precise operation. Thanks to the possibility of mounting on a panel or rail, it finds application in switchboards, control cabinets and other electrical installations. The rated operating power for AC-3 at 20 kW (at 400V) makes it suitable for controlling various receivers, including electric motors. The IP65 protection class guarantees resistance to dust and water ingress, allowing it to be used in harsh environmental conditions.
