Cam switch 40A, Two-speed switch with two separate windings, with yellow-red front, IP41 ŁK40-3.83139\P02

Rotary cam switch – reliable switching in your installation

This 40A rated, two-pole rotary cam switch is a robust solution for controlling electrical circuits. Designed for both professional and home use, it provides safe and efficient switching of two separate windings. The yellow-red front panel (IP41) facilitates identification and signaling of the circuit status.

Construction and application

A rotary cam switch is a device used to manually switch electrical circuits. The ŁK40-3.83139\P02 model features a two-pole design, meaning it can select from two separate settings. It is ideal for applications requiring a change in motor rotation direction or selection from two independent power circuits. The possibility of indirect mounting provides installation flexibility in various configurations. Made of durable plastic, it guarantees durability and resistance to mechanical damage.

Key features and benefits

• High resistance to environmental conditions: IP65 protection class on the front panel provides protection against dust and water jets, making it ideal for use in harsh industrial environments.
• High rated power: The rated power for AC-3 is 20 kW at 400 V, allowing control of even demanding loads.
• Safety of use: Rated continuous current of 40 A and high short-circuit strength (Icm 1.5 kA) ensure effective protection of the electrical installation.
• Durable construction: The housing material made of plastic guarantees corrosion resistance and long-term operation.
• Installation flexibility: Indirect mounting option facilitates integration with various switchgear systems.
• Clear identification: The yellow-red front panel facilitates quick identification of the switch status and improves work safety.
• Wide range of applications: Excellent for controlling electric motors, heaters and other devices requiring a change in operating direction or selection from several power circuits.

Technical parameters in practice

Rated continuous current of 40 A means that the switch can safely operate with a load of that intensity for a long time without the risk of overheating or damage. Rated power of 20 kW at 400 V allows connection of devices with significant power, and high short-circuit current (1.5 kA) provides protection against the effects of sudden overvoltages. The housing material made of plastic is lightweight and easy to process, which facilitates the installation and maintenance of the device. IP65 protection class guarantees reliable operation even in a humid or dusty environment.
