Cam switch 63A, three-phase starter switch (0,Y,A), front panel mounting enclosed yellow/red SK63-4.831\P08

Three-Phase Starter Switch – Reliable Motor Control

This 63A three-phase cam switch is a robust solution for motor starting and safe switching of electrical circuits. Designed for both industrial applications and installations requiring frequent switching, it provides reliable operation and long service life. The yellow-red front (P08) facilitates visual identification of the switch status.

Construction and Application

The cam switch SK63-4.831\P08 is designed for panel mounting, providing convenient installation and operation. Its design allows for changing the direction of motor rotation (0-Y-∆), making it a versatile tool in many applications. Made of durable plastic, it is resistant to mechanical damage and ensures safe use. The IP65 protection rating guarantees protection against dust and water jets, enabling operation in harsh environmental conditions.

Key Advantages

• High mechanical resistance: Robust construction ensures long-lasting and trouble-free operation even with intensive use.
• Versatility: The ability to change the motor rotation direction (0-Y-∆) expands the range of applications.
• Safety: IP65 protection protects against external factors, minimizing the risk of failure and ensuring operator safety.
• Easy installation: Designed for panel mounting, which simplifies installation and integration with existing infrastructure.
• Suitable for working in harsh conditions: A wide operating temperature range (-40°C to +70°C) allows for use in demanding industrial environments.
• Solid connections: Screw connection of the main contacts ensures a secure and durable connection of the wires.
• High rated value: Rated continuous current of 63A and the ability to connect circuits with a power of up to 18 kW (AC-3, 400V) allow for use in demanding applications.

Technical Parameters in Practice

A continuous rated current of 63A means that the switch can safely operate with a load of this value for a long time. The rated switching power of 18 kW at 400V allows for controlling motors with significant power. The switching angle of 30°-45°-90° provides precise control over the motor starting process. Mechanical durability of 3 million switching cycles guarantees a long service life of the device, even with frequent use. Short-circuit withstand current of 1.2 kA provides protection against the effects of short circuits and overvoltages.
