Cam switch 25A, 1-0-2 Disconnector (2-pole), panel mounting front grey knob black ŁK25-2.8338\P03

Cam switch – reliable circuit switching

This two-pole cam switch, catalog number ŁK25-2.8338\P03, is a robust solution for frequent switching of electrical circuits. Designed for both panel mounting and enclosure mounting, it finds application in control panels, switchgear, and anywhere manual circuit changeover is required. The construction with a gray housing and black knob ensures convenient operation and clear identification.

Construction and application

The 1-0-2 type cam switch allows selection between three positions: switching on one circuit, switching off both, or switching on the second circuit. This versatile solution is ideal for controlling various loads, e.g., motors, heaters or lighting. Execution in IP65 standard guarantees protection against dust and water jet, which makes it suitable for operation in harsh industrial conditions. Front mounting facilitates integration with existing installations.

Parameters and user features

The switch is characterized by high technical parameters ensuring safe and reliable operation. The continuous rated current is 25 A, allowing operation of devices with significant power consumption. It ensures safety in high-voltage installations thanks to the rated insulation voltage of 690 V. The rated switching power (AC-3) is 7 kW (230 V), 13 kW (400 V) and 10 kW (690 V), enabling control of motors with different power. Mechanical endurance of 3 million switching cycles guarantees long device life even with intensive use. Compatibility with a wide range of cables ensures a connection cable cross-section in the range of 2.5…6 mm². High resistance to dust and water ingress confirmed by the IP65 protection degree and a secure connection of cables thanks to the torque of the terminal screws at 1.2 Nm further enhance the value of this product.

The switch design has been tested for resistance to vibration, impact and the influence of atmospheric factors, which confirms its reliability in various working conditions. Different front versions (I, II, III) are available to adapt the switch to specific application requirements. The possibility of extending the switch in multiples of 12.5 mm increases mounting flexibility.
