Cam switch connector 80A, Disconnector 0-1 (3-pole), front panel mounting lockable yellow/red SK80-2.8211\P08

Universal cam switch for various applications

This three-pole cam switch SK80, which also functions as an isolating switch, is a versatile solution for switching and connecting electrical circuits. It offers a rated current of 80A and is designed for panel mounting, making it easy to integrate into various installations. The yellow-red plate and lockable knob provide additional safety and readability.

Construction and practical application

SK80 cam switches are characterized by a modular construction with segments and double cams. This allows for configuring individual connection programs tailored to specific needs. The ability to set the knob stroke angles at 30°, 45° or 90° (depending on the model) ensures precision and flexibility in circuit control. It will work well in both industrial applications and building installations.

• Power switches: ideal for switching off motors with load (AC3, AC23).
• Load connection: perfectly handles resistive loads and heating elements.
• Switches: finds application in transformers, welding machines and for switching the direction of rotation of three-phase motors.
• Switching elements: used in motor starters (star-delta) and as pole links in high-speed motors.

Key features and benefits

• Compliance with standards: meets the requirements of PN-EN 60947-3 and IEC 60947-3, guaranteeing safety and reliability.
• High protection: thanks to tunnel terminals and external insulated bridges, it provides a degree of protection IP20 regardless of the connection configuration.
• Durability and reliability: silver-plated contacts and copper elements minimize transition resistance, and the construction screwed with steel pins ensures long-term operation.
• Configuration flexibility: the ability to build a switch consisting of up to 7 segments (14 pairs of contacts) allows for the implementation of unusual connection programs.
• Resistance to external conditions: metal elements protected with an electrolytic coating eliminate oxidation, and high resistance to vibrations, shocks and humid heat ensures reliable operation in harsh industrial conditions.
• Safety: panel and enclosure versions achieve a degree of protection IP65, and an optional mechanism to prevent door opening (in built-in models) further increases operating safety.
• Ecology: meets the requirements of Directive RoHS 2002/95/WE – does not contain substances harmful to the environment.

The continuous rated current is 80A, the rated insulation voltage is 690V, and the rated power at AC-3 (400 V) is 22 kW. The switching angle is adjustable in the range of 45° to 90°, and the degree of protection of the front part is IP65.
