Cam switch disconnector 63A, 0-1 switch (6-pole), in OB3 housing with yellow/red lockable front ŁK63-3.8210\OB3ZC

Cam switch – reliable switching in your installation

This six-pole cam switch with a rated current of 63A is a solid solution for frequent circuit switching. The design with a lockable front (yellow/red) not only ensures safe use but also resistance to environmental conditions. The device is supplied in a complete OB3 housing, which simplifies installation and ensures it is ready to use straight out of the box.

Functionality and application

The switch is designed for applications requiring frequent switching of electrical circuits, e.g. in motor control systems, power distribution boards or industrial machines and equipment. The possibility of selecting the 0 position allows for safe disconnection of the circuit during maintenance or repair. The switch, thanks to the screw connection of the main contacts, enables easy and secure connection of wires. The rated operating power for AC-3 at 20 kW (at 400V) demonstrates its capabilities in more demanding applications.

Key features and benefits

• Durable construction: The housing made of plastic provides durability and resistance to mechanical damage.
• High degree of protection: The IP65 protection class guarantees protection against dust and water jets, making it ideal for use in harsh industrial environments.
• Safe use: The lockable front minimizes the risk of accidental contact with live parts.
• Versatility: Possibility of mounting in various configurations thanks to a wide range of available accessories (although they are not part of this specific product).
• Designed for continuous operation: The rated continuous current of 63A allows for long-term operation without the risk of overload.
• Easy installation: The complete device in the OB3 housing simplifies the installation process and minimizes the time required to start up the system.
• Designed for frequent switching: The design of the cam switch is specifically designed for applications requiring frequent switching operations, ensuring reliability and long device life.

Technical parameters in practice

The rated switching power AC-3 of 20 kW at a voltage of 400V means that this switch is able to handle loads typical of medium-power electric motors. The rated continuous current of 63A provides sufficient power reserve for most industrial and commercial applications. The lack of normally open or normally closed auxiliary contacts means that the device focuses on the basic switching function, which translates into simplicity of operation and reliability. The housing material – plastic – provides lightness and good electrical insulation.
