Cam switch 80A, three-phase starter switch (0,Y,A), panel mounting, gray front, black knob SK80-4.831\P03

Cam switch – reliable switching of loads

The SK80 cam switch is a versatile device combining the functions of a switch and an isolating switch. It expands the SK switch range with higher current ranges, enabling the creation of advanced switching programs thanks to its 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 practical application

The switch design allows for flexible adaptation to needs – by selecting the number of teeth of the drive mechanism, it is possible to obtain a knob stroke angle of 30°, 45° or 90°. The offered model is designed for panel mounting (P designation) and is characterized by a gray housing with a black knob. It finds application in a wide spectrum of applications, from motor power switches (AC3, AC23), through the connection of resistive loads and heating elements, to switches in transformers and motor starters (star-delta). It will also work in motor direction switches and as a switching element in welding equipment.

Key features and benefits

• Versatility: Possibility of configuring the switching program thanks to the segmented design and adjustable knob stroke angles.
• Safety: Compliance with PN-EN 60947-3 and IEC 60947-3 standards ensures a high level of safety.
• Durability: Made of silver-plated contacts and copper minimizes transition resistance, and steel pins screw the switch along its entire length ensuring mechanical strength.
• Protection: Tunnel terminals and insulated external bridges guarantee a degree of protection IP20 regardless of the implemented switching program.
• Resistance: Metal elements protected by electrolytic protective coating eliminate oxidation, and drive mechanisms ensure the ability to limit the formation of an electric arc.
• Mounting: Easy panel mounting thanks to the dedicated P03 version with a nameplate and black knob.
• Compliance: Meets the requirements of RoHS Directive 2002/95/EC – no hazardous substances.
