Cam switch 63A, Three-phase starter switch (0,Y,A), in OB3 enclosure with lockable front panel ŁK63-4.831\OB3Z

Universal cam switch for demanding applications

This three-phase 63A cam switch, designed for circuit switching (0-Y-Δ), is a robust and reliable solution for both professional installers and end-users. The OB3 enclosure construction provides high resistance to external conditions and mechanical protection of internal components. Designed for use in low-voltage electrical installations, it performs perfectly as a switch, isolator, changeover switch or control switch.

Construction and functionality

The switch is characterized by high quality and durability. Made of durable plastic, it is resistant to mechanical damage and the effects of atmospheric factors (IP65 protection rating). Screw connection of the main contacts guarantees a secure and safe connection of the wires. The OB3 enclosure provides additional protection against moisture and dust, which is particularly important in harsh industrial conditions. The possibility of mounting on a plate allows for flexible adaptation to different installation configurations.

Key advantages and parameters

• High reliability: Rated continuous current of 63A and rated operating power of 20 kW (for AC-3, 400V) ensure stable operation even under heavy loads.
• Versatility: The switch allows for 0-Y-Δ circuit configuration, making it an ideal solution for various applications.
• Safety: IP65 protection rating guarantees protection against dust and water ingress, and the solid construction ensures safe use.
• Durability: Made of high-quality materials and precise workmanship guarantee a long service life.
• Easy installation: The design allows for easy mounting on a plate or in a distribution box.
• Mechanical strength: Designed to operate in a temperature range from -40°C to +70°C, ensuring reliability in harsh environmental conditions.
• No auxiliary contacts: The lack of auxiliary contacts simplifies installation and reduces costs associated with additional control elements.

Applications

The cam switch finds application in:

• Electrical distribution boards
• Control cabinets
• Electric motors (star-delta switching)
• Industrial applications
• Building installations
• Emergency power systems
