Cam switch 15A, Dahlander's two-speed switch, in OB3 enclosure. ŁK15-4.8390\OB3

Dahlander Switch – Reliability and Versatility in One

This two-speed cam switch, also known as a Dahlander switch, is a robust solution for controlling electric motors and other devices requiring a change in direction of rotation or selection of two operating modes. Model ŁK15-4.8390\OB3 combines durability, safety and ease of installation, proving effective in both industrial and commercial installations.

Design and Application

The cam switch is a complete device in OB3 housing, which provides high protection against external factors (IP65). Designed for indirect mounting, it features a two-pole construction and screw connection of the main contacts. Thanks to the presence of the "0" position, it allows for safe disconnection of the circuit. The Dahlander switch finds wide application in controlling electric motors, heating systems, lighting systems and other devices requiring a change in working direction or selection from two operating modes. Its solid construction and high resistance to environmental conditions guarantee reliable operation even in harsh industrial conditions.

Key Features and Benefits

• High resistance to environmental conditions: IP65 protection class provides effective protection against dust and water jets, allowing the connector to be used in demanding industrial conditions.
• Safety of use: The presence of the "0" position allows for complete disconnection of the circuit, minimizing the risk of short circuit or damage to connected devices.
• Durability and reliability: Made of high-quality plastic and a solid construction guarantee long life and trouble-free operation.
• Versatility: The Dahlander switch is perfect for controlling electric motors, heating systems, lighting systems and other devices requiring a change in working direction or selection from two operating modes.
• Compliance with standards: Meets the requirements of PN-EN 60947-3 and IEC 60947-3, confirming its safety and quality.
• Efficiency: The rated operating power for AC-3 is 8 kW at 400 V, and the rated continuous current Iu is 15 A – parameters allowing operation of many types of devices.
• Installation flexibility: The switch is designed for indirect mounting, which facilitates its integration with various installation systems.

Additionally, it is worth mentioning the possibility of configuring cam switches by selecting the appropriate number of segments and the angle of the knob stroke (every 30°, 45° or 90°), which allows adaptation of the device to individual user needs. This allows you to create any connection programs depending on the position of the drive knob.
