Cam switch 80A, Disconnector 1-0-2 (3-pole), panel mounting front grey knob black SK80-3.8380\P03

Cam switch – reliable circuit switching

This SK80 cam switch, which also functions as an isolator, is a robust solution for connecting and disconnecting electrical circuits with a current of up to 80A. The design based on double cams allows for flexible creation of connection programs, tailored to the specific needs of the application. This device is used both in industrial installations and in applications requiring frequent switching of loads.

Construction and application

The SK80 switch is designed for front panel mounting and features a gray housing with a black knob. This ensures convenient operation and a clear visualization of the circuit status. The device is particularly useful in applications requiring switching of motors with load (AC3, AC23), connecting resistive loads and heating elements. It will also be suitable in transformer switches, welding equipment, and as an element for switching the direction of rotation of three-phase motors. The ability to configure the knob stroke angle (45° or 90°) increases the functionality of the device and allows it to be adapted to the specifics of a given installation.

Key features and benefits

• High reliability: Compliance with PN-EN 60947-3 and IEC 60947-3 standards guarantees the safety and long-term operation of the device.
• Versatility: 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.
• Durability: Silver-plated contacts and copper elements minimize transition resistance and ensure a stable connection for a long time. Steel pins screw the switch along its entire length, increasing its mechanical strength.
• Protection: Protection class IP20 (IP65 in control panel and enclosed versions) provides protection against accidental contact and environmental influences.
• Safety: Compliance with the RoHS 2002/95/WE Directive means the absence of hazardous substances, which is important for protecting the environment and user health.
• Easy installation: The design allows for simple mounting on the front panel.
• Flexibility: Possibility of using a mechanism to prevent the door from opening when the operator indicates the on state (applies to SK80).
