Cam switch 25A, Circuit switch 0-1-2-3, in OB1 enclosure. ŁK25R-2.8445\OB1

Universal cam switch for demanding applications

This cam switch with a rated current of 25A is a reliable solution for switching electrical circuits. It finds application in both industrial installations and more demanding commercial applications. Thanks to its robust construction and wide operating temperature range, it ensures long-lasting and safe operation. Model ŁK25R-2.8445\OB1 is supplied in a durable OB1 housing, which increases its resistance to mechanical damage and environmental factors.

Functionality and operating parameters

This switch stands out for its versatility thanks to the possibility of configuration with a different number of segments – from 1 to 15 (depending on the version). This allows it to be adapted to the specific needs of the installation. It is designed to operate at a rated insulation voltage of 690V and withstand impulse voltages up to 6kV. The rated switching power in category AC-3 is 7 kW at 230V, 13 kW at 400V and 10 kW at 690V, making it suitable for controlling various loads. The conventional rated short-circuit current is as high as 13 kA, providing effective protection against the effects of short circuits.

Construction and mounting

The switch has been designed with easy installation and convenient operation in mind. The IP65 protection class guarantees resistance to dust and water ingress, allowing it to be used in harsh environmental conditions. Connection cables with a cross-section from 2.5 mm² to 6 mm² can be fixed with a tightening torque of 1.2 Nm. Mechanical durability at the level of 3 million switching cycles ensures a long service life even with intensive use. Various versions of switches are available: rotary disconnectors, direction of rotation changes or Dahlander – allowing you to adapt the functionality to a specific task.
