Cam switch 40A, -4.8240 panel mounting front closure yellow/red ŁK40-4.8240\P08

Rotary switch – reliable circuit control

This 7-pole rotary switch, with a rated current of 40A, is a robust solution for frequent circuit switching. It finds application in both industrial installations and more demanding home applications. The enclosed design, with yellow-red marking, provides additional safety and easy identification of the circuit status.

Construction and application

A rotary switch is a mechanical device used for manual switching of electrical circuits. This model, thanks to the possibility of mounting on a panel (front), is ideal where direct control over the power supply is needed. The rated operating power for AC-3 at 20 kW allows operation of even demanding receivers. Made of durable plastic, it provides durability and resistance to mechanical damage. The IP65 protection class guarantees protection against dust and water jet – making it suitable for use in harsh environmental conditions.

Key features and benefits

• High mechanical resistance: Durable plastic construction ensures long-lasting and reliable operation.
• Safety of use: Enclosed design and clear color coding (yellow-red) minimize the risk of accidental circuit opening or incorrect operation.
• Versatility of mounting: Possibility of indirect mounting and front panel mounting facilitates integration with various control systems.
• Resistance to external conditions: IP65 protection class protects against dust and water, allowing use in demanding industrial conditions.
• Suitable for continuous operation: Rated continuous current of 40A enables safe operation in circuits with high load.
• Connection flexibility: Screw connection ensures secure and durable connection of wires.
• Configuration options: Available in a version with position 0, which facilitates safe disconnection of the circuit during maintenance or repair.

Technical parameters in practice

This rotary switch has been designed with reliability and safety in mind. The lack of normally open and changeover auxiliary contacts simplifies the construction, increasing its resistance to failure. The housing material – plastic – provides electrical insulation and corrosion resistance. The short-circuit withstand current of 0.5 kA and the switching surge current of 2 kA demonstrate its ability to withstand momentary overloads without damage. Designed to operate in temperatures from -25°C to +70°C, it will perform in a wide range of applications.
