Cam switch 40A, Disconnector 0-1 (3-pole), front panel mounting lockable yellow/red SK40-2.8211\P08

Multi-position cam switch – reliable circuit switching

This three-pole cam switch with a rated current of 40A is a robust solution for switching electrical circuits on and off. It is suitable for both industrial installations and public buildings where reliability and frequent switching are required. The front-sealed design, in yellow-red coloring, provides additional safety and easy identification of the circuit status.

Functionality and application

Cam switches, such as this model, are versatile elements of low-voltage electrical installations. They can function as disconnectors, switches, and control switches. Thanks to the segmented structure with double cams, it is possible to create any connection programs depending on the position of the drive knob. This is particularly useful in applications requiring flexibility and adaptation to specific needs. The rated operating power for AC-3, at 400V, is 12 kW, which allows for handling various loads.

Mounting and durability

The switch is designed for mounting on a panel or plate, making it easy to integrate with existing infrastructure. Made of durable plastic, it ensures long-lasting and reliable operation even in harsh industrial conditions (temperature from -40°C to +70°C). The IP65 protection class on the front side guarantees resistance to dust and moisture, increasing safety. The connection of the main contacts is made using screw connections – a proven method ensuring secure and durable connection of wires. It meets the requirements of PN-EN60947-3 and IEC 60947-3, which confirms its compliance with applicable safety standards.
