Cam switch 63A, Circuit switch 0-1-2-3, front mounting grey knob black ŁK63-2.8445\S03

Cam switch for demanding applications

This cam switch, designed for rail mounting, is a robust solution for connecting and switching electrical circuits. Model ŁK63-2.8445, in OB2 housing, offers reliable operation in a wide range of applications – from industrial installations to advanced control systems. The design allows switching between circuits 0-1-2-3, providing flexibility in installation configuration.

Construction and characteristic features

The switch is characterized by high quality workmanship and durability. The housing made of plastic provides insulation and protection against external factors. The degree of protection IP41 and IP65 guarantees resistance to dust and moisture, allowing operation in harsh environmental conditions. Rail mounting simplifies installation and servicing. The black knob provides convenient operation and precise circuit switching.

Technical parameters and application

The device is adapted to work with a continuous rated current of 63A and a rated insulation voltage of 690V. The rated switching power in category AC-3 is 20 kW at 400V and 500V and 10 kW at 690V, making it suitable for high-power loads. The rated short-circuit current Icm is 2.2 kA, which ensures effective protection of the installation in the event of a short circuit. Therefore, the switch finds application in power distribution boards, motor control systems and other applications requiring reliable switching of circuits with high current intensity. Mechanical durability at the level of 3 million switching cycles guarantees long device life even with intensive use.
