Cam switch 25A, Three-phase starter switch (0,Y,A), front base mounting grey knob black ŁK25-4.831\B03

Universal cam switch for extended installations

This three-phase cam switch with a rated current of 25A is a reliable solution for controlling electrical circuits. Designed for both industrial and commercial building applications, it ensures safe and efficient operation of devices. The design allows switching between different configurations (0, Y, Δ), making it a versatile element in motor starting systems and other loads. Solid construction and high resistance to external conditions guarantee long-term operation even in demanding environments.

Construction and application

The cam switch ŁK25-4.831\B03 features front mounting, which simplifies installation on panels and in switchboards. The gray housing with a black knob provides clear identification and convenient operation. The device is particularly useful in applications requiring frequent circuit switching, such as motor starters, direction of rotation changes, or mode selection. The three-phase starter switch (0,Y,A) allows for flexible connection configuration depending on the application needs – from direct starting to star-delta starting.
