Cam switch 40A, Dahlander two-speed switch, front panel mounting, grey knob black ŁK40-4.8390\S03

Universal cam switch for wide application

This two-pole cam switch, also known as a Dahlander switch, is a reliable solution for controlling electrical circuits. Designed for both industrial and public building installations, it provides safe and efficient load switching. The design allows for rail mounting, making it easy to integrate with existing systems.

Construction and functionality

The switch is characterized by a solid plastic construction, ensuring durability and resistance to mechanical damage. Designed for rail mounting, it has a screw connection of the main contacts, guaranteeing a secure and reliable connection of the wires. Equipped with a black knob, it allows for intuitive operation and precise circuit switching. The IP65 protection class provides protection against dust and water jets, allowing it to be used in harsh environmental conditions. Thanks to the presence of the "0" position, it is possible to completely disconnect the circuit, increasing safety during maintenance or repairs.

Key advantages for installers and users

• Versatility: Possibility of use in various electrical installations – from simple lighting circuits to more complex control systems.
• Safety: IP65 protection class and the presence of the "0" position minimize the risk of electric shock and equipment damage.
• Durability: Made of high-quality materials guarantees long life and reliable operation.
• Easy installation: Design for rail mounting simplifies and speeds up installation.
• High efficiency: Rated power of 20 kW at 400 V AC-3 allows handling even demanding receivers.
• Adapted to work in difficult conditions: Wide operating temperature range (-40°C to +70°C) allows use in various industrial environments.
• Compliance with standards: Meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards, confirming its safety and quality.

Technical parameters in practice

The rated continuous current of 40 A allows for safe loading of the switch without the risk of overheating or damage. The possibility of indirect mounting provides flexibility in choosing the installation location. The lack of normally open and normally closed auxiliary contacts simplifies the electrical diagram and reduces installation costs. Resistance to vibrations, shocks, damp heat and salt mist makes it an ideal choice for demanding industrial applications. The switch is designed to work with wires with a cross-section of 4...10 mm², which ensures adequate conductivity and connection safety.
