YCFK Composite Switch

The YCFK intelligent capacitor switching device uses thyristor switch and magnetic holding switch in parallel operation.

It has the advantage of controllable silicon zero-crossing switch at the moment of connection and disconnection, and zero power consumption of the mag- netic holding switch during normal connection.

Product Details

General

The YCFK intelligent capacitor switching device uses thyristor switch and magnetic holding

switch in parallel operation. It has the advantage of controllable silicon zero-crossing switch

at the moment of connection and disconnection, and zero power consumption of the mag

netic holding switch during normal connection. This switch has significant advantages such

as no impact, low power consumption, and high lifespan, and can replace contactors or

thyristor switches. It is widely used in low-voltage reactive power compensation systems.

Selection

Note: For Three-phase Individual Compensation (Y), the maximum rated current reaches 63A; the rated current corresponds to the compensation capacitor capacity as shown in the table.

Wiring diagram

Precautions:

Before use, it is essential to carefully check the terminal screws of the main circuit connection. They must be securely tightened; otherwise, loose screws during operation can easily lead to damage to the switch.

(The incoming and outgoing wire terminals of this product are equipped with anti-loosening self-locking nuts, effectively ensuring that the prod- uct does not experience secondary loosening of the connections due to factors such as transportation and vibrations after the connections are securely made.)
