Cam switch 15A, Dahlander's two-speed switch with direction of rotation change, panel mounting, gray front, black knob ŁK15-7.8538\P03

Universal cam switch for various applications

This two-speed cam switch, also known as a Dahlander switch with reverse rotation, is a robust and versatile solution for controlling motors and other electrical devices. Designed for both panel mounting and installation in distribution boards (although this is not its primary purpose), it offers reliable operation and ease of use. The knob design provides convenient setting changes, and the high IP65 protection rating guarantees safety in harsh industrial environments.

Construction and functionality

The switch features a two-pole design, making it ideal for applications requiring the simultaneous switching of two circuits. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The connection of the main contacts is made using screw connections, which simplifies installation and ensures a secure electrical connection. The switch has a "0" position, allowing for complete disconnection of the circuit. Additionally, this model allows for changing the direction of rotation, which is particularly useful in applications requiring precise motion control.

Applications and benefits

• Versatility: Ideal for controlling electric motors, drives, and other devices requiring change of rotation direction or selection of one of two speeds.
• Durability: Made of high-quality materials, resistant to mechanical damage and environmental conditions.
• Safety: IP65 protection rating protects against dust and water ingress, ensuring safe operation in harsh industrial environments.
• Easy installation: Indirect mounting and screw connections simplify installation and integration with existing systems.
• Reliability: Designed for continuous operation with a rated current of 15A and a rated power for AC-3 of 8 kW.
• Flexibility: Possibility of use in various configurations thanks to a wide range of available segments (up to 16).
• Clarity: Clear markings and ergonomic knob design facilitate operation and minimize the risk of errors.

Additional technical information: the rated continuous current Iu is 15A, and the rated short-time withstand current Icw(1s) is 0.5 kA. The mechanical life is 3 million switching cycles, guaranteeing a long service life. The ambient operating temperature is from -25°C to +70°C and the storage temperature is also within this range. The cross-section of the connection cables is 1.5...4 mm².
