Cam switch 16A, Dahlander two-speed switch, in OB3 enclosure. ŁK16R-4.8390\OB3

Universal cam switch for demanding applications

This two-speed Dahlander switch, enclosed in a robust OB3 housing, is a reliable solution for controlling electric motors. Designed for both industrial installations and construction applications, it combines solid construction with functionality. The design allows for easy mounting and safe operation, and the high degree of protection IP65 guarantees resistance to harsh environmental conditions.

Construction and application

The cam switch is used to change the direction of rotation or speed of an electric motor. The ŁK16R-4.8390\OB3 model is a two-speed Dahlander switch, which means it allows switching between two different motor speeds. Made of high-quality plastic, it provides durability and resistance to mechanical damage. The switch with the 0 position allows for safe disconnection of the circuit. The connection of the main contacts is made using a screw connection, which ensures a secure and stable connection of the wires.

Key features and benefits

• High resistance to external conditions: IP65 protection class protects against dust and water jets, making it ideal for indoor and outdoor applications.
• Designed for motors with a power of 8 kW (AC-3, 400 V): Allows controlling motors with significant power, which translates into a wide range of applications.
• Two-speed Dahlander design: Allows flexible adjustment of the motor speed to the needs of the application.
• Solid plastic housing: Provides durability and resistance to mechanical damage and corrosion.
• Safe to use: Has a 0 position, allowing for complete disconnection of the circuit.
• Easy installation: Screw connection of the main contacts simplifies and speeds up installation.
• Suitable for working in difficult conditions: Withstands temperatures from -40°C to +70°C, guaranteeing reliability in various working environments.
• Mechanical durability: Designed for 3 million switching cycles - a guarantee of long-term operation.

User parameters

The rated continuous current is 16 A, which ensures safe operation of the device with proper selection of wires (cross-section 1.5...4 mm²). The conventional rated short-circuit current is 13 kA - an important parameter for ensuring the safety of the installation in the event of a short circuit. The switch is intended for indirect mounting and is not suitable for installation in distribution boards. The lack of normally open and normally closed auxiliary contacts simplifies the construction and reduces the risk of errors during connection.
