20A rotary switch, direction of rotation changeover switch L-0-P, panel mounting, grey front, black knob SK20-3.8368\P03

Cam switches – reliable control of electrical circuits

This SK20 cam switch, designed for panel mounting, is a robust solution for switching on and off currents in low-voltage electrical circuits. It is ideal as a switch, isolator, changeover switch or control switch in industrial and construction installations. The design with a black knob and grey bezel provides convenient operation and clear identification of the switch position.

Functionality and technical parameters

The SK20 switch is characterized by high reliability and durability. Adapted to work in harsh conditions, it meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards. The rated continuous current of 20A and the ability to operate with a load of up to 4kW at 400V AC-3 guarantee its versatility. The IP65 degree of protection of the front side provides protection against dust and water jets, which is particularly important in demanding industrial environments. Designed for indirect mounting, it allows flexible adaptation to different installation configurations. The segmented construction with double cams allows for the creation of individual connection programs, and the possibility of obtaining knob rotation angles of 30°, 45° or 90° increases the functionality of the device.

Application and benefits

This model of a direction-of-rotation changeover switch L-0-P finds application in a wide range of applications, from controlling electric motors to switching on and off various loads. Its solid plastic construction ensures durability and resistance to mechanical damage. Panel mounting facilitates access and operation, and clear switch position markings minimize the risk of errors. The lack of normally open and normally closed auxiliary contacts simplifies the installation diagram in applications where they are not required. Thanks to this, the SK20 switch is a practical and effective solution for professionals and end-users looking for a reliable element for their electrical installations.
