Cam switch disconnector 20A, 0-1 switch (5-pole), in OB11 enclosure. SK20-3.8220\OB11

Cam switch – reliable switching in demanding conditions

This 5-pole cam switch, in a robust OB11 housing, is a solid solution for frequent switching of electrical circuits. Designed for both professional applications and end-users requiring reliability, it combines construction durability with ease of installation and operation. This switch is used in motor control, power circuit switching, and other applications requiring manual load switching.

Construction and functionality

The switch is characterized by a solid construction based on a cam mechanism, ensuring precise and reliable switching. Made of high-quality plastic, it is resistant to mechanical damage and environmental influences. The OB11 housing provides a high degree of protection IP65, which guarantees safe use even in difficult conditions – preventing dust and water from entering the device. The ability to set to the "0" position allows for safe disconnection of the circuit during maintenance or repair. The connection of the main contacts is made using screw connections, which ensures a stable and reliable connection of the wires.

Parameters and applications

The rated continuous current of 20A and the rated power for AC-3 of 4 kW make the switch ideally suited for controlling various electrical devices. The ability to operate at a rated insulation voltage of 690V and high resistance to shock and vibration (compliant with IEC standards) guarantee long-term and trouble-free operation of the device. The switch with a knob is easy to operate and allows for intuitive circuit control. Thanks to its compact size, it can be easily mounted even in limited space.
