Cam switch 15A, Dahlander two-speed switch, \P01 ŁK15-4.8390\P01

Cross cam switch for industrial and domestic applications

This dual-speed cross cam switch, also known as a Dahlander switch, is a reliable solution for controlling electric motors. Designed for panel mounting, it offers convenience and safety when switching circuits. The plastic construction provides good insulation and resistance to mechanical damage. Model ŁK15-4.8390\P01 is distinguished by its versatility – it can be used in both industrial installations and more demanding domestic applications.

Construction and functionality

A cross cam switch is an element used to manually switch electrical circuits. In this model, the dual-speed design allows you to choose between two different connection configurations, which is particularly useful in applications requiring a change in motor rotation direction or selection of different power ranges. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The IP65 protection rating guarantees resistance to dust and water jets, allowing it to be used in harsh environmental conditions. The connection of the main contacts is realized by screw connections, which ensures a secure and stable connection of the wires.

Key features and benefits

• Versatility: The Dahlander switch allows you to change the direction of motor rotation or select different power ranges, making it an ideal solution for a variety of applications.
• Durability: The plastic construction provides resistance to mechanical damage and corrosion.
• Safety: The IP65 protection rating protects against dust and water ingress, minimizing the risk of short circuits and failures.
• Easy installation: Designed for indirect mounting, which simplifies integration with existing installations.
• Suitable for continuous operation: Rated continuous current of 15A and high mechanical durability (3 million switching cycles) guarantee reliable operation in demanding conditions.
• Wide voltage range: Rated insulation voltage Ui is 500V and impulse withstand voltage Uimp is 4kV – this ensures safety of use in various electrical installations.
• With 0 position: The presence of a "0" position increases safety by allowing complete disconnection of the circuit.

Technical parameters in practice

Rated operating power for AC-3 at 400V is 8kW – this means that the switch can be safely used with loads of this power. Short-time thermal current Icw(1s) is 0.5kA – informs about the ability of the switch to withstand short-term overloads without damage. Connection wire cross-section 1.5…4 mm² allows connection of wires of different thickness, adapting to the specifics of the installation. Lack of auxiliary contacts (normally open, normally closed and changeover) simplifies the design and reduces the cost of the device without affecting its basic functionality – controlling the electric motor.
