Cam switch 63A, Three-phase starter switch (0,Y,A), in OB4 enclosure with lockable front ŁK63-4.831\OB4Z

Star-delta starter and circuit switching cam switch

This three-phase cam switch with a current of 63A is designed for starting motors in a star-delta configuration (0-Y-∆), as well as for switching electrical circuits. It is mounted in an OB4 housing with a lockable front, providing additional safety and protection against interference. The device finds application in both industrial installations and more demanding commercial applications.

Construction and application

A cam switch is a reliable device used for manual switching of electrical circuits. In this model, the ability to select positions 0, Y (star) and ∆ (delta) allows for efficient starting of three-phase motors, reducing starting current and minimizing network load. The OB4 housing provides solid protection against external factors, and the lockable front increases user safety. The device's design allows for rail mounting, which simplifies installation and integration with existing systems.

Key features and benefits

• Versatility: Ideal for starting motors in a star-delta configuration and as a circuit switch.
• Safety: OB4 housing with a lockable front provides protection against accidental contact with conductive elements and protects against unauthorized access.
• Durability: Made of high-quality materials, guarantees long-lasting and reliable operation even in harsh industrial conditions.
• Easy installation: Designed for rail mounting, which simplifies the installation process and integration with existing electrical infrastructure.
