Cam switches SK – a versatile solution for switching loads

Cam switches SK are reliable devices combining the functions of an isolator and a switch. A wide current range and the ability to configure the switching program make them ideal for various applications in electrical installations. The SK80 model, with a rated current of 80A, is particularly useful in applications requiring high reliability and flexibility.

Construction and application

The SK80 cam switch with a black knob, designed for panel mounting, allows changing the direction of rotation (L-O-P). The segmented construction with double cams allows creating individual switching programs tailored to the specific needs of the installation. Thanks to the possibility of obtaining knob step angles of 30°, 45° or 90°, the load can be precisely controlled. It finds application in motor power switches (AC3, AC23), transformer switches, welding equipment and as a starting element for three-phase motors (star-delta). It will also be useful for switching the direction of rotation of three-phase motors.

Key features and benefits

• Versatility: The ability to configure the switching program allows the switch to be adapted to different applications.
• Safety: Compliance with PN-EN 60947-3 and IEC 60947-3 standards ensures a high level of safety.
• Durability: Made of silver-plated contacts and copper minimizes transition resistance and ensures long-term operation. Steel pins screw the switch along its entire length, increasing its mechanical strength.
• Protection: Protection class IP20 (contact part) and IP65 (panel and enclosed versions) protects against environmental influences.
• Compliance with directives: Meeting the requirements of Directive RoHS 2002/95/WE guarantees the absence of harmful substances in the composition.
• Flexible mounting: Various mounting methods are available: for panel mounting (P), on TS35 rail (BS), in enclosure (OB17, OB18) and for built-in installation (D).
• High arc fault limiting capacity: Drive mechanisms minimize the risk of arc formation during switching.
• Possibility of building a switch consisting of up to 7 segments: This allows the implementation of even the most complex switching programs (up to 14 pairs of contacts).

SK80 cam switches are a solid and reliable solution for professionals and end customers looking for high-quality components for electrical installations. A wide range of applications and configuration options make them the ideal choice for a variety of projects.
