Cam switch disconnector 63A, 0-1 switch (4-pole), in OB3 enclosure. ŁK63-2.8210\OB3

Universal cam switch for demanding applications

This four-pole cam switch with a rated current of 63A is a robust solution for switching electrical circuits. Designed for both industrial and building installations, it offers reliability and safety. Equipped with a "0" position, it allows for complete disconnection of the circuit, which is crucial during maintenance or repairs. OB3 housing provides high resistance to external factors, and screw connections guarantee secure and durable wire connections.

Construction and application

A cam switch is a rotary device used to manually switch electrical circuits. The version with OB3 housing is particularly useful in places exposed to harsh environmental conditions, such as humidity or dust. Thanks to the possibility of configuration with a different number of segments (up to 6), it can be adapted to specific installation needs. It is ideal for applications where frequent circuit switching is required, e.g. in switchboards, machine controls or lighting systems. The design allows for easy mounting and intuitive operation.
