Dahlander switch for motor control – reliability and functionality

This cam switch, also known as a Dahlander switch, is a robust solution for controlling electric motors. Designed for panel mounting, it offers convenient change of rotation direction and two-speed operation. The construction allows for flexible adaptation to various applications, and high resistance to environmental conditions guarantees long-lasting and trouble-free operation.

Construction and application

This switch is particularly useful in applications requiring precise motor control, such as industrial machines, lifting systems or conveyors. Thanks to the ability to change the direction of rotation and select two speeds, it provides versatility and process optimization. Made of durable plastic, it is resistant to mechanical damage and atmospheric influences. The IP65 protection class guarantees safe use even in harsh industrial conditions.

Key features and benefits

• Versatility: The Dahlander switch allows you to change the direction of rotation and choose between two motor speeds, increasing its functionality in various applications.
• Durability: Made of high-quality plastic, it ensures long-lasting and reliable operation even in demanding industrial conditions.
• Safety: The IP65 protection class protects against dust and water ingress, ensuring safe operation in harsh environments.
• Easy installation: Designed for panel mounting, which simplifies installation and integration with existing control systems.
• High resistance: Meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards, guaranteeing compliance with applicable safety standards. Additionally resistant to vibrations, shocks, damp heat and salt mist.
• High power: The rated power for AC-3 is 8 kW at 400 V, allowing control of motors with significant power.
• Suitable for continuous operation: The rated continuous current Iu is 16 A, allowing long-term operation without the risk of overheating or damage to the device.
• Flexible connections: Connection of the main contacts is made using a screw connection, ensuring a secure and stable electrical connection.

Technical parameters in practice

The materials used and the construction of the switch ensure its reliability even with frequent switching (mechanical durability: 3,000,000 switching cycles). The cross-section of the connection cables 1.5…4 mm² allows connection of cables of different thicknesses, adapting to individual installation needs. It is worth noting the high short-circuit current withstood by the device (Icw(1s) = 0.9 kA), which increases the safety of the installation in the event of a short circuit. Additionally, the possibility of indirect mounting expands the range of applications for the switch.
