Cam switches SK – reliable switching and disconnecting of circuits

SK80 cam switches are versatile devices combining the functions of a switch and an isolating switch. They extend the SK switch range with higher current ranges, enabling the creation of advanced connection programs thanks to their segmented design with double cams. This solution is ideal for both professional installers and end-users looking for a reliable and configurable element in their electrical installation.

Construction and application

The SK80-2.8211\P03 cam switch is designed for panel mounting. Its construction allows for flexible adaptation to the needs of a specific application – the angle of rotation of the drive knob can be set to 30°, 45° or 90°, providing up to 12 knob positions. The device finds application in many areas, including:

• Power switches for switching off motors with load (AC3, AC23).
• Connection of resistive loads and heating elements.
• Switches in transformers and welding machines.
• Three-phase motor direction switches.
• Switching elements in motor starters (star-delta).

Key features and benefits

SK80 cam switches are characterized by high quality workmanship and compliance with applicable standards (PN-EN 60947-3, IEC 60947-3). The use of tunnel terminals and external insulated bridges ensures an IP20 degree of protection regardless of the connection program implemented. Additional advantages include:

• High reliability: Drive mechanisms limit the formation of electric arc, and silver-plated contacts minimize transition resistance.
• Durable construction: The switch screwed with steel pins along its entire length guarantees mechanical strength.
• 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.
• Safety: Compliance with the requirements of Directive RoHS 2002/95/WE – no hazardous substances.
• Protection: IP65 degree of protection in panel-mounted and enclosed versions ensures safe operation in harsh environmental conditions.
• Mounting: Designed for panel mounting with M6 screws with a tightening torque of 4.4 Nm.

The device is intended for operation in enclosed spaces (degree of pollution 3 - industrial application) at an ambient temperature of -40°C to +70°C. The continuous rated current is 80A, and the rated operating power at AC-3 and 400V is 22 kW.
