Cam switch 32A, Direction of rotation changeover switch L-O-P, in OB2 enclosure with lockable front plate ŁK32R-3.8368\OB2Z

Rotary reversing switch

This rotary reversing switch, with a rated current of 32A, is designed for the safe and reliable reversal of three-phase motors. Model ŁK32R-3.8368, mounted in OB2 enclosure with a closed front, provides solid protection against external factors and mechanical damage. The three-pole design allows for versatile use in various electrical installations.

Construction and application

A rotary reversing switch is an element used to manually switch electrical circuits. In this case, this model is specifically designed to change the direction of rotation of motors – a function particularly useful in industrial applications, construction machinery or control systems. The OB2 enclosure with a closed front guarantees a high degree of protection IP65, which means resistance to dust and water jets. The use of screw connection ensures a secure and durable connection of the wires.

Key features and benefits

• Durability and reliability: Made of high-quality plastic, the switch is resistant to mechanical damage and ensures long-term operation.
• Safety: The IP65 protection class protects against moisture and dust, minimizing the risk of short circuits and failures.
• Versatility: Designed for three-phase motors with a rated operating power of up to 17 kW (for AC-3 at 400V), making it suitable for many applications.
• Easy installation: Designed for indirect mounting, which facilitates integration with existing electrical installations.
• Suitable for operation in harsh conditions: A wide range of operating temperatures (-40°C to +70°C) allows it to be used in demanding industrial environments.
• High resistance to external factors: Meets standards for vibration, shock and salt mist resistance, confirming its reliability in various operating conditions.
• Application: Motor direction change L-0-P – ideal where a change in the direction of machine or device operation is required.

Operating parameters

The rated continuous current is 32A, and the conventional short-circuit current reaches 12kA – these parameters guarantee safe operation even under high loads. The switch has a "0" position, which allows for complete disconnection of the circuit, increasing safety during maintenance or repair. The cross-section of the connecting wires should be from 4 to 6 mm², and the tightening torque of the terminals is 1.2 Nm – ensuring a stable electrical connection.
