The plastic housing and high IP65 protection rating guarantee durability and resistance to harsh environmental conditions. This model, catalog number ŁK40-2.8338\P03, is ideal for both professional installers and end-users looking for a reliable solution.

Construction and application

A rotary cam switch is a device used to manually switch electrical circuits. This model features a cam mechanism with a black knob, allowing for precise and confident operation. The 1-0-2 configuration allows you to choose between two circuits or disconnect them (position 0). This is particularly useful in applications requiring frequent load changes or source selection. Applications in industry, workshops or laboratories are wide-ranging – from machine control to lighting switching.

Key features and benefits

• Durability and reliability: The housing made of high-quality plastic provides resistance to mechanical damage and external factors.
• High resistance to environmental conditions: The IP65 protection rating guarantees protection against dust and water jets, allowing operation in harsh industrial conditions.
• Safety of use: The cam mechanism ensures reliable circuit switching, minimizing the risk of accidental disconnection.
• Universal mounting: Designed for panel mounting, making it easy to integrate with existing installations.
• High switching power: The rated power for AC-3 is 20 kW at 400V, allowing to handle significant loads.
• Suitable for frequent switching: Mechanical durability of 3 million switching cycles guarantees long life even with intensive use.
• Safe design: Lack of return to position 0 increases safety, preventing accidental circuit activation after shutdown.
• Flexible connections: Screw connection of the main contacts ensures a secure and durable connection of wires with a cross-section from 4 to 10 mm².

Technical parameters in practice

The rated continuous current of 40A allows for safe power supply to devices with high power consumption. The rated insulation voltage Ui is 690V, and the impulse withstand voltage Uimp is 6kV – these parameters provide protection against overvoltages and short circuits. The switch is adapted for indirect mounting and has certificates of compliance with applicable safety standards. Thanks to this, you can be sure that the device meets all required quality and safety standards.
