Rotary cam switch for reversing direction – reliability and versatility

This rotary cam switch with a rated current of 25A is a solid solution for controlling motors and other devices requiring a change in direction of rotation. Designed for both professional and end-user applications, it offers safe and efficient operation in various electrical installations. The design with a knob allows for precise switching between three positions: L-0-P (left-zero-right), making it an ideal element in drive control systems.

Construction and application

A rotary cam switch is a mechanical device that allows switching electrical circuits on and off by turning the knob. This ensures reliable control of devices, and its segmented construction allows configuring a connection program tailored to specific needs. It finds wide application in enclosures of low-voltage electrical installations as a switch, disconnector, switch or control switch. Its versatility makes it readily chosen by installers and end-users.

Key features and benefits

• Durability and safety: The housing made of plastic provides resistance to mechanical damage and electrical insulation. The IP65 protection class guarantees protection against dust and water jets, allowing operation in harsh environmental conditions.
• Universal mounting: Possibility of indirect mounting allows flexible adaptation to various machine and device structures.
• High rated power: The rated power for AC-3 is 13 kW at 400 V, which enables control of devices with significant power.
• Precise switching: Three poles and the 0 position provide precise control over the electrical circuit.
• Durable construction: Made of high-quality materials guarantees long life and reliability of the device. The mechanism with the knob’s angle of rotation allows creating connection programs tailored to specific application requirements.
• Safety of use: Meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, confirming compliance with applicable safety standards. Additionally, resistant to vibrations, shocks and atmospheric factors (within certain ranges).
• Easy installation: Screw connection of the main contacts facilitates mounting and connection of wires.

Additional information: The switch has a C characteristic, which means it reacts more slowly to short current surges – this is particularly important when starting devices with a motor, which generate a high starting current.
