Cam switch disconnector 25A, 0-1 switch (3-pole), in OB1 flush-mounted enclosure ŁK25R-2.8211\OBP1

Universal cam switch for safe circuit switching

This three-pole 25A cam switch, with a 0-1 disconnector function, is a reliable solution for controlling and isolating electrical circuits. The product is supplied in a durable, flush-mounting OB1 housing, which ensures an aesthetic appearance and protection against mechanical damage. It is ideal for both industrial installations and public buildings or homes.

Design and application

The switch is designed for frequent switching of AC-3 circuits with a power of up to 13 kW at a voltage of 400V. The cam mechanism-based design guarantees a secure and stable connection, minimizing the risk of arcing and failure. The possibility of flush mounting facilitates integration with existing electrical infrastructure and ensures a neat appearance of the installation. The 0-1 switch allows for complete disconnection of the circuit, which is crucial during maintenance or repair.
