Cam switch 15A, Dahlander's two-speed switch with reverse rotation, P01 ŁK15-7.8538\P01

Universal cam switch for motor control

This two-speed Dahlander switch, designated ŁK15-7.8538\P01, is a robust solution for controlling electric motors. Designed for both professional and amateur applications, it provides reliable switching of direction and speed. The design allows for panel mounting, making it easy to integrate with existing installations.

Construction and application

The cam switch is used to change the direction of rotation and select two speeds in electric motors. It is particularly useful in applications requiring precise motion control, such as production machines, close-range transport systems, or lifting devices. Made of durable plastic, it provides resistance to mechanical damage and environmental factors. The IP65 protection rating guarantees safe operation even in harsh industrial conditions – protecting against water jets and dust.

Key features and benefits

• Two-speed speed change: Allows you to adjust the motor speed to specific application needs.
• Direction of rotation change: Allows for precise control of the motor's working direction.
• Durable construction: The plastic housing provides resistance to damage and long device life.
• High resistance to external conditions: IP65 protection rating guarantees safe operation in dusty and humid environments.
• Rated current 15A: Allows use with motors up to 8 kW (for AC-3, 400V).
• Intermediate mounting possible: Facilitates integration with various types of installations.
• Safety of use: Rated insulation voltage Ui is 500V, and impulse withstand voltage Uimp is 4kV – this provides protection against overvoltage and short circuits.
• Wide operating temperature range: The device can operate at temperatures from -25°C to +70°C, making it suitable for use in various climates.

Technical parameters in practice

The rated continuous current Iu of 15A means that the switch is adapted to work with constant loads for a long time without the risk of overheating. The rated switching current Ie in category AC-3 (motor control) is 8.7A at 400V and 8.7A at 500V – these values indicate its ability to safely switch electric motors on and off. The tightening torque of the terminals at 1.2 Nm ensures a secure connection of the wires, minimizing the risk of loosening connections during operation. Mechanical durability of 3 million switching cycles guarantees long and trouble-free operation of the device.
