Cam switch 32A, Disconnector 0-1 (3-pole), in OB1 housing with lockable front ŁK32R-2.8211\OB1Z

Rotary switch – reliable switching in your installation

This 32A rotary switch is a solid solution for frequent switching of electrical circuits. Designed for both professional and demanding users, it provides safe and convenient operation. Equipped with a 0 position, it allows for complete disconnection of the circuit, which increases safety during maintenance and repairs. The housing made of plastic guarantees durability and resistance to mechanical damage.

Design and application

The rotary switch from the ŁK32R-2.8211\OB1Z series is designed for indirect mounting, which provides flexibility in choosing the installation location. Its design based on a mechanical cam switch ensures high reliability and long life. The switch has 4 poles, allowing you to control three-phase electrical circuits and additional auxiliary circuits. Connection of the main contacts is made using screw connections, which ensures a secure and durable connection of the wires. The IP65 protection class guarantees protection against dust and water jets, which enables its use in harsh environmental conditions.

Key features and benefits

• High mechanical resistance: The plastic housing protects against damage and ensures long-term operation.
• Safety of use: It has a 0 position, allowing for complete disconnection of the circuit during maintenance or repair work.
• Versatility: Designed for indirect mounting, which makes installation easier in various configurations.
• Application in harsh conditions: IP65 protection class provides resistance to dust and water, enabling operation in demanding environments.
• High rated power: The rated power for AC-3 is 17 kW at 400V, allowing it to handle high-power loads.
• Durability: The cam switch mechanism is designed for a large number of switching cycles (3 million).
• Adapted to different wire cross-sections: Supports wires with a cross-section of 4…6 mm².

Technical parameters in practice

The rated continuous current of 32A means that the switch can safely operate with a load of this value for a long time. The conventional short-circuit current rating of 12 kA indicates its ability to withstand short-term overloads associated with a short circuit in the installation. The housing material - plastic - provides not only mechanical strength but also electrical insulation. The lack of auxiliary contacts (normally open and normally closed) means that the device focuses on the basic function of switching the circuit without additional signaling or remote control capabilities.
