Cam switch 63A, three-phase starter switch (0,Y,A), in OB3 enclosure. ŁK63-4.831\OB3

Motor and electrical device starter switch

This three-phase cam switch ŁK63-4.831\OB3 from SPAMEL is a reliable element used for manual switching on and off of electrical circuits. It finds wide application in industry, workshops and construction installations, especially when operating electric motors, transformers and other devices requiring a change of direction of rotation or operating mode. The switch design allows for star-delta (0-Y-A) configuration, which is crucial for starting three-phase motors.

Construction and application

The cam switch is a complete device in OB3 housing, which ensures its durability and resistance to mechanical damage and external factors. The housing made of plastic guarantees safe use, and the IP65 protection class protects against dust and water ingress, allowing operation in difficult environmental conditions. The switch is designed for plate mounting, which facilitates its integration with existing installations. Screw connection ensures a secure and stable connection of wires.

Key features and benefits

• Versatility: The ability to switch between different configurations (0-Y-A) makes the switch ideal for a variety of applications.
• Durability: The OB3 housing made of high-quality plastic provides long-lasting protection against damage.
• Safety: IP65 protection class guarantees resistance to dust and water, minimizing the risk of failure caused by external factors.
• Easy installation: Designed for plate mounting, it facilitates integration with existing electrical installations.
