Cam switch for panel mounting – reliable circuit switching

The SK80 cam switch is a versatile device combining the functions of a switch and an isolating switch. Designed for panel mounting, with a yellow-red front, it is a solid solution for installers and end-users requiring reliable switching of three-phase circuits. Model SK80-4.831 is primarily a star-delta starter switch (0-Y-∆), ideal for use in motor starting and other applications requiring circuit configuration changes.

Construction and application

SK80 cam switches are characterized by a segmented construction with double cams, allowing for the creation of any switching programs depending on the position of the drive knob. The ability to adjust the angle of the knob stroke (45° or 90°) allows for precise adaptation to specific application needs. The device finds application in:

• 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, star-delta starters and connection of high-speed motor poles.

Features and benefits

The construction of the SK80 switch ensures high reliability and safety of use. The most important features include:

• Compliance with standards: Meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards, guaranteeing safety and compatibility with other installation elements.
• High protection: Protection class IP20 (IP65 in enclosure) provides protection against contact and environmental influences.
• Durable construction: Made of silver-plated contacts and copper minimizes transition resistance and ensures long-term operation of the device. The screwed steel pin construction further increases 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 switching programs according to individual customer needs.
• Safety: A mechanism to prevent the door from opening (when mounted in a distribution cabinet) increases operating safety.
• Wide current range: Continuous rated current of 80A allows the switch to be used in demanding industrial applications.
• Mounting: Designed for panel mounting, making it easy to integrate with existing control systems.

Thanks to these features, the SK80 cam switch is an optimal solution for both professional installers looking for a reliable component for building switchboards and control systems, and for end-users expecting safe and efficient switching of electrical circuits.
