0-star-triangle switch in CS 16 12 PN1 enclosure 004773216

Star-delta switch – reliable motor starting

This 0-star-delta switch in a CS 16 12 PN1 enclosure is a key element of electrical installations, ensuring smooth and safe starting of three-phase motors. It enables reduction of starting current, protecting both the motor and the other elements of the installation from overload. This is an ideal solution for both professional installers and end-users looking for a reliable and durable component.

Functionality and application

This switch is used to change the motor winding configuration from star to delta, which reduces the current drawn during starting. Once the motor reaches its appropriate rotational speed, it switches to the delta configuration, providing full power. The design with a "0" position provides additional safety by allowing complete disconnection of the circuit. This is particularly important in applications requiring frequent switching of the motor on and off.

Construction features and operating parameters

The four-pole switch with a rated continuous current of 16A is designed to operate with a load of up to 7.5 kW at a voltage of 400V (AC-3). Made of high-quality materials, and the screw connection of the main contacts guarantees secure and durable electrical connections. The knob as an actuator provides convenient and precise operation. The complete device in a CS 16 enclosure facilitates mounting and provides additional protection against external factors.
