Cam switch 63A, three-phase starter switch (0,Y,A), base rail mounting front grey knob black SK63-4.831\BS03

Starter switch for demanding applications

This three-phase cam switch with a rated current of 63A is a reliable solution for switching electrical circuits on and off. Designed for busbar mounting, it is ideal for industrial and commercial installations where high resistance to environmental conditions and frequent load switching are required. The design allows for 0-Y-∆ (star-delta) connection configuration, making it a versatile element in motor control systems.

Functionality and durability in one device

The switch is characterized by a solid plastic construction, providing mechanical and electrical insulation. The IP65 protection class guarantees protection against dust and water jets, allowing it to be used in harsh working conditions. The rotary mechanism provides convenient and precise operation, and the possibility of indirect mounting facilitates integration with existing installations. A continuous rated current of 63A and high short-circuit strength (1.2 kA) ensure safe and long-lasting operation.

Key features for professionals and users

• Versatility: The ability to configure 0-Y-∆ connections allows adaptation to different motor control schemes.
• Durability: Solid plastic construction and high IP65 protection class ensure reliability in harsh industrial conditions.
• Safety: High short-circuit strength (1.2 kA) protects the installation from damage.
• Mounting: Designed for busbar mounting, which facilitates installation and servicing.
• Performance: The rated operating power for AC-3 is as high as 18 kW at 400V, allowing it to handle even demanding loads.
• Wide range of applications: Ideal for motor starters, circuit switching and as an element of control systems.
