Cam switch disconnector 63A, 1-0-2 switch (3-pole), in OB4 enclosure. ŁK63-3.8380\OB4

Cam switch – reliable circuit switching

This three-pole cam switch with a rated current of 63A is a solid solution for frequent switching of electrical circuits. The design with a "0" position provides additional safety during maintenance and repairs, allowing for complete disconnection of the circuit. This model is used in both industrial installations and commercial and residential construction, where reliability and manual control are required.

Construction and application

The cam switch ŁK63-3.8380\OB4 is a complete device in an OB4 housing, which means it is ready for installation immediately after unpacking. Designed for rail mounting, it is characterized by a high degree of protection IP65, which guarantees resistance to dust and water jets – an ideal solution for demanding environments. Made of durable plastic, it provides durability and corrosion resistance. The switch with a knob allows for intuitive operation and precise circuit control.

The rated operating power of up to 20 kW (AC-3 at 400V) makes it suitable for various applications, from electric motors to heating devices. The possibility of connecting screw terminals ensures a secure and safe electrical connection. This makes the switch suitable for circuits requiring frequent switching under load.
