Cam switch 40A, Three-phase reversing starter switch, panel mount front grey knob black ŁK40-5.8538\P03

Three-phase starter switch – reliable change of rotation direction

This 40A three-phase cam switch is a robust solution for controlling electric motors. Designed for panel mounting, it offers convenient change of rotation direction, making it an ideal choice for both professional installers and end users. The construction with a black knob and gray housing provides an aesthetic appearance and easy operation.

Construction and application

Cam switch ŁK40-5.8538\P03 is a device used to manually switch electrical circuits, especially for starting three-phase motors and changing their direction of rotation. Made of durable plastic, it ensures long-lasting and reliable operation in various conditions. The IP65 protection class guarantees resistance to dust and water spray, allowing its use even in more demanding industrial environments. Designed for indirect mounting, it allows flexible adaptation to existing infrastructure.

Key features and benefits

• High resistance to external conditions: IP65 protection class protects against dust and moisture, ensuring reliable operation even in demanding conditions.
• High rated power: Rated power of 20 kW at 400 V allows controlling motors with significant power.
• Safety of use: Rated continuous current of 40 A and high short-circuit strength (2 kA) provide effective protection of the electrical installation.
• Convenient operation: Black knob allows intuitive change of motor rotation direction.
• Solid construction: Made of high-quality plastic guarantees durability and resistance to mechanical damage.
• Installation flexibility: Indirect mounting allows easy integration with existing control systems.
• Position 0: Has a clearly marked position 0, which increases safety and facilitates operation of the device.
• Screw connection: Provides secure and durable connection of electrical wires.

Technical parameters in practice

The rated continuous current at 40A means that the switch can safely operate with a load up to this value for a long time without the risk of overheating or damage. In turn, the high value of short-circuit withstand current (2 kA) provides protection against the effects of sudden overvoltages and short circuits in the electrical installation. The IP65 protection class is not only resistance to dust, but also to water spray – which is particularly important in industrial environments or exposed to moisture. The housing material – plastic – provides light weight of the device and good electrical insulation.
