Cam switch 25A, three-phase starter switch (0,Y,A), in OB13 enclosure. SK25-4.831\OB13

Three-Phase Starter Switch – Reliability and Functionality in One

This three-phase cam switch with a rated current of 25A is a solid solution for controlling motors and other devices requiring frequent circuit switching. Designed for both professional and end-user applications, it offers high reliability and easy installation. Equipped with a "0" position, it ensures safe disconnection of the load.

Design and Application

The cam switch SK25-4.831\OB13 is enclosed in a durable OB13 housing made of plastic, which guarantees resistance to mechanical damage and external factors. The IP65 protection rating protects against dust and water jets, allowing installation in various environmental conditions. Designed for panel mounting, it is ideal for building control panels, operator panels and other electrical installations. The switch with 0-Y-∆ (0-star-delta) characteristics is used for starting three-phase motors, allowing to limit the starting current and ensure a smooth start.

Key Advantages
