Cam switch disconnector 25A, 0-1 switch (4-pole), in OB2 enclosure with yellow/red front plate ŁK25-2.8210\OB2C

Cam switch – reliable circuit switching

Cam switch 25A, in a 0-1 disconnecting configuration with four poles, is a solid solution for frequent switching of electrical circuits. Mounted in a durable OB2 housing, with a clearly marked yellow-red front, it provides both safety and easy identification. It is an element intended for use in electrical installations where reliability and resistance to environmental conditions are required.

Construction and application

The switch construction is based on a cam mechanism, which guarantees reliable and stable circuit switching. This switch is used in controlling electric motors, switching power supplies, and in other applications requiring manual switching of circuits with a current of up to 25A. The OB2 housing protects the internal components from mechanical damage and external factors, and the IP65 protection class provides resistance to dust and moisture. The yellow-red front makes it easier to visually identify the function of the switch.

Parameters and usage features

This model is distinguished by high technical parameters, which translate into long life and trouble-free operation. The continuous rated current is 25A, and the rated switching power in category AC-3 is 7 kW at 230V and 13 kW at 400V. The switch can withstand a short-circuit current of up to 13 kA, providing additional safety for the installation. The possibility of mounting on a panel or in a distribution box increases its versatility. The cross-section of the connection cables is 2.5...6 mm², which allows connection of cables of different thicknesses. Mechanical durability at the level of 3 million switching cycles guarantees long-term use even in intensive working conditions. The ambient operating temperature is from -40°C to +70°C, making it suitable for use in harsh climatic conditions.
