Cam switch 63A, three-phase starter switch (0,Y,A), panel mounting, gray front, black knob SK63-4.831\P03

Universal cam switch for demanding applications

This three-phase 63A cam switch is a reliable solution for switching electrical circuits. Designed for both professional and end-user applications, it offers a robust construction and a wide range of possibilities. Model SK63-4.831\P03 stands out for its ability to switch between 0, Y (star) and Δ (delta) configurations, making it an ideal choice for motor starting and other applications requiring voltage and current changes.

Construction and application

The cam switch is mounted on the control panel, providing convenient installation and operation. Its cam mechanism-based design guarantees smooth and precise circuit switching. Thanks to the IP65 protection class, it is resistant to dust and water ingress, allowing it to be used in harsh environmental conditions. Made of durable plastic, it ensures long-lasting and reliable operation. It finds application in control cabinets, electrical switchboards, and in industrial machines and equipment.

Key features and benefits

• Versatility: The ability to switch between 0, Y and Δ configurations expands the range of applications – from motor starting to voltage changes in circuits.
• Durability: Made of high-quality plastic and with a solid construction, it ensures a long service life even in demanding working conditions.
• Safety: The IP65 protection class protects against external factors such as dust and water, increasing safety.
• Easy installation: Mounting on the control panel simplifies installation and integration with existing systems.
• High power: Rated continuous current of 63A and rated power for AC-3 up to 18 kW allow for handling loads with significant power.
• Precision: The cam mechanism ensures smooth and precise circuit switching, minimizing the risk of damage or interference in the operation of devices.
• Protection: Rated short-circuit current at 0.7 kA provides additional protection for the electrical installation.
• Wide temperature range: The ability to operate in a temperature range from -40°C to +70°C makes it suitable for use in various climatic conditions.

Technical parameters in practice

The rated continuous current of 63A means that the switch can safely operate with a load of this value for a long time without overheating or damage. The rated power for AC-3 of 18 kW allows you to connect devices with significant power, such as electric motors or industrial heaters. The IP65 protection class guarantees protection against dust and water jet, which is particularly important in humid or dusty industrial environments. Screw connection of the main contacts ensures a secure and durable connection of electrical wires.
