Cam switch disconnector 25A, 0-1 switch (3-pole), in OB3 enclosure. ŁK25-2.8211\OB3

Cam switch – reliable switching in demanding conditions

This three-pole cam switch, with a rated current of 25A, is a robust solution for frequent switching of electrical circuits. It finds application in both industrial installations and commercial construction. Made of high-quality materials and housed in a durable OB3 enclosure, it ensures long-lasting and trouble-free operation even in harsh environmental conditions. Model ŁK25-2.8211\OB3 offers a 0-1 disconnector, meaning the circuit can be completely disconnected.

Construction and application

A cam switch is a mechanical device used to manually switch electrical circuits. Its cam-based design ensures reliable and secure connection and disconnection of contacts. The OB3 enclosure protects against external factors such as moisture, dust and mechanical damage. This allows the switch to be used both indoors and outdoors (IP65 protection). It is ideal for controlling motors, heaters, lighting and other electrical devices requiring frequent switching.
