Cam switch 80A, Disconnector 1-0-2 (3-pole), panel mounting front closure yellow/red SK80-3.8380\P08

Cam switches SK – a versatile solution for professionals

SK80 cam switches are advanced devices combining the functions of a switch and an isolating switch. They extend the SK family offer with higher current ranges, offering flexibility in creating connection programs thanks to their modular construction and dual cams. The ability to configure the knob stroke angles (30°, 45° or 90°) allows adaptation to specific application needs. These devices are designed for installation in enclosed spaces, meeting industrial requirements (pollution degree 3).

Construction and application

The offered switches are available in various mounting versions: for panel mounting (P), on TS35 rail (BS), in an enclosure (OB17, OB18) and for built-in installation (D). The wide range of applications includes motor power switches with AC3 and AC23 loads, connection of resistive loads, switches in transformers and welding equipment, as well as switches for three-phase motor rotation direction and starting elements (star-delta). Therefore, SK80 switches find application in various electrical installations – from industrial to commercial.

Key features and benefits

• Compliance with standards: The switches meet the requirements of PN-EN 60947-3 and IEC 60947-3 standards, guaranteeing safety and reliable operation.
• High protection: The use of tunnel terminals and external insulated bridges provides an IP20 degree of protection regardless of the connection configuration.
• Durability and reliability: Drive mechanisms minimize arcing, and silver-plated contacts and copper elements reduce transition resistance.
• Configuration flexibility: The ability to build a switch consisting of up to 7 segments (14 pairs of contacts) allows for the implementation of unconventional connection programs tailored to individual customer needs.
• Environmental resistance: Metal elements protected with electrolytic protective coating eliminate oxidation, and panel and enclosure versions achieve a degree of protection of IP65.
• Safety: They meet the requirements of Directive RoHS 2002/95/WE, which means the absence of hazardous substances. In built-in versions, a mechanism is available to prevent the door from opening when switched on.
