Cam switch 15A, Three-phase starter switch (0,Y,A), panel mounting front grey knob black ŁK15-4.831\P03

Three-phase starter switch for panel mounting

This three-phase cam switch, catalog number ŁK15-4.831\P03, is a robust solution for controlling electrical circuits. Designed for both professional and demanding users, it provides reliable switching and installation protection. The construction allows for panel mounting, facilitating operation and integration with existing systems.

Characteristics and application

The ŁK15 P cam switch is a device used for manual switching of electrical circuits. This model, in a 0-Y-∆ (0-star-delta) configuration, is particularly useful in applications related to the starting of three-phase motors. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The IP65 protection rating guarantees safe use even in harsh environmental conditions – it protects against dust and water jets.

Construction and product features

The switch construction is based on a solid cam mechanism, ensuring smooth and precise switching. The black knob facilitates operation, and the gray front provides clear labeling. The possibility of indirect mounting increases installation flexibility. The switch has 3 poles and is adapted for connecting wires using screw connections. The rated continuous current is 15 A, and the rated power for AC-3 at 400 V is 8 kW – making it suitable for many industrial and workshop applications. Additionally, the lack of auxiliary contacts (normally closed and changeover) simplifies the connection diagram in some applications.
