Cam switch 63A, three-phase starter switch (0,Y,A), base rail mounting frontal yellow-grey knob red SK63-4.831\BS04

Universal cam switch for disconnecting and controlling circuits

This three-phase cam switch with a rated current of 63A is a reliable solution for switching on and off electrical circuits. Designed for use in industrial and commercial installations, it ensures safe and efficient operation. The design allows switching between different configurations (0, Y, Δ), making it a versatile element in motor control systems and other devices.

Construction and application

The switch is made of durable plastic, which provides good insulation and resistance to mechanical damage. The IP65 protection rating guarantees protection against dust and water jets, allowing installation in harsh environmental conditions. Designed for rail mounting, it offers flexibility in integration with existing installations. Thanks to the ergonomic red knob, operation is intuitive and convenient. It is an ideal element for both installers and end-users looking for a reliable solution for switching circuits.

Key features and benefits

• High mechanical resistance: The plastic housing provides durability and resistance to damage.
• Wide range of applications: The ability to switch between 0, Y, Δ configurations allows use in various electrical systems.
• Safe to use: IP65 protection protects against dust and water, ensuring safe operation in harsh conditions.
• Easy installation: Designed for rail mounting, which facilitates integration with existing installations.
• Current endurance: Rated continuous current of 63A and the ability to withstand short-circuit currents (1.2 kA) ensure reliable operation even under heavy loads.
• Versatility: Suitable for use in enclosed spaces with a degree of pollution 3 (industrial).
• High switching power: Rated operating power for AC-3 is as high as 18 kW at 400V – sufficient for most industrial applications.
• Solid connections: Screw connection of the main contacts guarantees a secure and durable connection of the wires.

Technical parameters in practice

Rated continuous current of 63A means that the switch can safely operate with a load of up to 63 amps for a long time without overheating or damage. The ability to withstand short-circuit currents (1.2 kA) provides additional safety in the event of unexpected surges. The switching angle of 30°-45°-90° allows for precise circuit control. The operating temperature from -40°C to +70°C makes the product resistant to extreme weather conditions.
