Cam switch 25A, Dahlander two-speed switch with reversing, long black knob ŁK25R-7.8538\P09

Universal switch for various applications

This 25A rotary switch, also known as a Dahlander switch, is a versatile device for switching electrical circuits on and off. It is suitable for both industrial installations and applications requiring a change in the direction of motor rotation. The design with a long black knob ensures convenient and precise operation. This switch is particularly useful in situations where control over two-speed motors with the ability to change their direction of operation is needed.

Construction and functionality

The switch is characterized by a solid plastic construction, ensuring durability and resistance to mechanical damage. The IP65 protection rating guarantees safe use even in harsh environmental conditions – it is dustproof and protected against water jets. The switch has two poles and allows changing the direction of rotation, making it an ideal solution for various applications. The connection of the main contacts is made using screw connections, which ensures a secure and reliable connection of the wires. The lack of auxiliary contacts (normally open and normally closed) simplifies installation in applications where they are not required.

Application and benefits

This rotary switch finds application in many areas, including:

• Motor control: Ideal for controlling electric motors with the ability to change the direction of rotation and select speed (two-speed).
• Industry: It works perfectly in machines and industrial equipment requiring frequent switching of circuits.
• Building automation: It can be used in building automation systems to control various electrical devices.
• Indirect mounting: The possibility of indirect mounting facilitates integration with various structures and control panels.
• High reliability: Rated continuous current of 25A and high mechanical endurance (3 million switching cycles) guarantee long-lasting and trouble-free operation of the device.
• Safety: The IP65 protection rating protects against external factors, ensuring safe operation in various conditions.
• Versatility: The Dahlander switch allows flexible control of devices, offering the possibility of choosing the speed and direction of motor rotation.
• Compliance with standards: The device meets appropriate safety standards, confirming its high quality and reliability.

Additional technical information: the rated power for AC-3 at 400V is 13 kW, and the rated insulation voltage is 690V. The lack of return to the 0 position ensures that the selected switch position is maintained until manually changed.
