Cam switch disconnector 63A, 1-0-2 switch (3-pole), in OB4 enclosure with lockable front ŁK63-3.8380\OB4Z

Cam switch – reliable switching in your installation

This three-pole cam switch with a rated current of 63A is a solid solution for switching electrical circuits. Equipped with a 1-0-2 disconnecting mechanism, it allows you to choose between three positions, making it ideal for applications requiring flexibility and control. Rail-mounted, with an OB4 housing with a lockable front, it provides safety and protection against interference.

Design and parameters

The switch is designed for durability and reliability. The housing made of high-quality plastic protects the internal components from mechanical damage and environmental influences. The IP65 protection rating guarantees resistance to dust and water jets, allowing installation in various conditions. The rated operating power for AC-3 is 20 kW at 400V, which demonstrates its efficiency. The connection of the main contacts is made using screw connections, providing a secure and stable connection of wires with a cross-section from 4 to 10 mm².

Application and benefits

This cam switch finds application in a wide range of electrical installations – from industrial to commercial and residential. It will be perfect for:

• Industrial machines and equipment: as a control element for motors and other energy consumers.
• Electrical switchboards: as a switching element for power circuits.
• Automation systems: as a control element for production processes.
• Heating installations: for switching heating circuits.

Thanks to its design and parameters, this switch offers a number of benefits:

• High reliability: solid construction and high-quality materials ensure long-term, trouble-free operation.
• Safety of use: the housing with a lockable front protects against accidental contact with live parts.
• Flexibility: the ability to choose from three positions (1-0-2) allows adaptation to different needs.
• Resistance to external conditions: the IP65 protection rating guarantees operation in difficult environmental conditions.
• Easy installation: rail mounting facilitates installation and servicing.

Additionally, the switch is characterized by high mechanical durability – it withstands as many as 3 million switching cycles, which guarantees years of operation without the need for replacement. The short-circuit rated current Icw(1s) is 1.2 kA and the ultimate short-circuit breaking capacity Icm is 2.2 kA, providing additional safety for the installation in the event of overloads or short circuits.
