Cam switch 100A, three-phase starter switch (0,Y,A), panel mounting, yellow-grey knob, red SK100-4.831\P04

Starter Switch – Reliable Control of Electrical Circuits

This three-phase cam switch with a rated current of 100A is a robust solution for controlling and disconnecting electrical circuits. Designed for both industrial applications and installations requiring frequent switching of loads, it ensures safety and efficient operation. The design allows for panel mounting, facilitating integration with existing control systems. The yellow-grey housing with a red knob provides good visibility and intuitive operation.

Functionality and Application

The cam switch SK100-4.831\P04 is particularly useful in applications requiring frequent switching of loads, such as:

• Three-phase motor starting (0-Y-Δ configuration).
• Switching resistive and heating loads.
• Application in transformers and welding machines.
• Changing the direction of rotation of three-phase motors.
• Construction of forward/reverse switches for high-speed motors.

Thanks to the possibility of configuring the knob stroke angles (45° or 90°), it can be adapted to specific application needs. The IP65 protection rating guarantees resistance to dust and moisture, allowing operation in harsh environmental conditions.

Design and Features

The switch is made of high-quality plastic, ensuring durability and resistance to mechanical damage. Screw terminals facilitate connection of wires, and the segmented construction allows for the creation of various connection programs depending on the position of the drive knob. Equipped with a "0" position, it allows for safe disconnection of the circuit. It complies with PN-EN 60947-3 and IEC 60947-3 standards, confirming its compliance with European safety standards. The rated operating power for AC-3 is 25 kW at 400 V, making it suitable for high-power applications. Additionally, the lack of auxiliary contacts makes it a solution dedicated to simple switching applications.
