Cam switch 25A, Dahlander two-speed switch, panel mounting front grey knob black SK25-4.8390\P03

Panelboard Rotary Switches – Reliability and Functionality

This 25A rotary switch, also known as a Dahlander two-speed switch, is a robust solution for controlling electric motors and other devices requiring frequent changes in direction of rotation or speed. Designed for panel mounting, it offers convenient operation and durability, making it an ideal choice for both professional installers and end users. Made of high-quality plastic, it provides resistance to mechanical damage and external factors.

Design and operating parameters

The switch features a double-pole design and a "0" position, allowing for safe circuit disconnection. A rated continuous current of 25A and the ability to operate at 690V guarantee a wide range of applications in various electrical installations. The IP65 protection rating provides protection against dust and water jets, enabling operation in harsh industrial conditions. Screw connection of the main conductors ensures a secure and durable electrical connection. A black knob facilitates operation and allows for precise circuit switching.

Application and benefits

This model of rotary switch is primarily used in controlling electric motors, where changes in direction of rotation or speed are required. The Dahlander switch enables smooth changes in engine parameters, which translates to increased efficiency and performance of the entire system. Panel mounting provides easy access and convenient operation, and high resistance to external conditions guarantees long-lasting and trouble-free operation. Additionally, the lack of a need for additional protection (conventional short-circuit current rating 13kA) simplifies installation and reduces costs. The possibility of indirect mounting increases installation flexibility.
