Cam switch 25A, Direction of rotation changeover switch L-O-P, in OB2 enclosure with lockable front plate ŁK25R-3.8368\OB2Z

Universal cam switch for motor control

This three-pole cam switch, with a rated current of 25A, is a reliable solution for changing the direction of rotation of three-phase motors. Model ŁK25R-3.8368\OB2, in combination with the OB2 enclosure, ensures both safety and ease of use. Designed for both professional applications in industrial installations and for end-users who need precise control over electrical devices.

Construction and functionality

The switch allows switching between three positions: left (L), zero (0) and right (P), making it ideal for controlling motors requiring a change in direction of rotation. Made of durable plastic, it is resistant to mechanical damage and ensures long-term operation. The closed front provides additional protection against contamination, and the IP65 protection rating guarantees resistance to dust and moisture – which is particularly important in harsh working conditions. Mounting in the OB2 enclosure facilitates installation and provides additional protection.

Parameters and application

The rated operating power for AC-3 at 400V is 13 kW, allowing the switch to be used in a variety of industrial applications. The continuous rated current at 25A ensures stable operation even under heavy loads. The switch has a screw connection of the main contacts, which facilitates the connection of wires. As it is a complete device in an enclosure, installation is quick and easy. In addition, the lack of normally open and normally closed auxiliary contacts simplifies the electrical diagram and minimizes the risk of errors during connection.
