Cam switch 25A, Direction of rotation changeover switch L-O-P, in OB4 housing. ŁK25R-3.8368\OB4

Universal reversing cam switch

This cam switch, with a rated current of 25A, is a reliable solution for controlling motors and other electrical devices. Designed for both professional and amateur applications, it provides safe and efficient change of rotation direction. Model ŁK25R-3.8368\OB4 is supplied in a durable OB4 housing, which increases its resistance to mechanical damage and ensures long-term operation.

Construction and application

The cam switch is used for manual switching of electrical circuits, in particular for changing the direction of rotation of three-phase motors. The L-O-P (left-zero-right) design enables precise device control. It is an ideal solution in applications requiring frequent changes in working direction, e.g. in construction machinery, industrial equipment or automation systems. Made of high-quality plastic, it is lightweight and easy to install. The IP65 protection class guarantees resistance to dust and water jets, allowing its use in harsh environmental conditions.

Key features and benefits

• High reliability: Rated current of 25A and high mechanical strength (3 million switching cycles) ensure long-lasting and trouble-free operation.
• Versatility: Possibility of use in various electrical devices requiring a change in the direction of rotation.
• Safety: The housing made of plastic and the IP65 protection class protect against electric shock and damage caused by external factors.
• Easy installation: Simple construction and screw connections facilitate installation and connection to existing electrical circuits.
• Durability: Resistance to vibrations, shocks and humid heat ensures stable operation even in demanding industrial conditions.
• Compliance with standards: Meets the required safety standards, confirmed by the certificates held (CE, RU, UA).
• Wide operating temperature range: The possibility of operation in a temperature range of -40°C to +70°C makes it suitable for operation in difficult climatic conditions.
• Rated operating power for AC-3 (400 V): 13 kW – allows operation of devices with significant power.

Technical parameters in practice

The rated switching power of 13 kW at 400 V means that this switch can be used with motors of significant power – typical for industrial applications. The rated short-circuit making capacity of 13 kA provides effective protection against the effects of short circuits. The cross-section of connection cables 2.5...6 mm² allows connection of cables of different thicknesses, adapting to the specifics of the installation. The lack of switchable auxiliary contacts (0) simplifies the construction and reduces the risk of failure. Screw connection of the main contacts ensures a secure and durable electrical connection.
