Cam switch 25A, Three-phase starter switch (0,Y,A), in OB3 enclosure with yellow/red sealable front. ŁK25R-4.831\OB3ZC

Universal cam switch for demanding applications

This seven-pole cam switch with a rated current of 25A is a reliable solution for switching electrical circuits. Designed for both industrial and building installations, it combines a robust construction with functionality, ensuring safe and efficient operation. Model ŁK25R-4.831\OB3 is supplied in a durable OB3 housing with a yellow and red lockable front – which facilitates identification and provides additional safety.

Construction and operating parameters

The switch is characterized by high resistance to environmental conditions, thanks to the IP65 protection rating of the front. The housing made of plastic provides durability and insulation. Designed for fixed mounting, it offers screw connections for cables with a cross-section of 2.5…6 mm². The rated operating power for AC-3 is 13 kW at 400V, making it suitable for controlling motors and other high-power devices. Values such as the rated short-circuit current of 13 kA and the short-time withstand current of 1 kA guarantee effective protection of the installation in the event of overloads or short circuits.

Functionality and application

The three-phase starter switch (0,Y,A) allows flexible control of electrical circuits. Thanks to the ability to switch between different configurations (0, Y, ∆), it finds application in starting three-phase motors and in applications requiring a change in circuit configuration. The "0" position ensures safe disconnection of the circuit. A mechanical durability of 3 million switching cycles guarantees a long service life even with intensive use. Meets safety requirements and has CE, RU and UA compliance certificates.
