Scope of application

It is suitable for AC 50Hz, rated working voltage to 400V, and agreed heating current to 90A for turning on and off the parallel capacitor bank to improve the power factor of the circuit.

Model meaning

Structure

The contactor is a direct-acting double-breakpoint structure, the contact system is arranged in two layers, and the upper layer has three pairs of pre-charge contacts and a matching resistor to form a surge inrush device. When it is closed, it is turned on for a few milliseconds, and then the working contact is turned on. The permanent magnet in the pre-filled contact is released under the reaction of the spring, and the resistance is disconnected to make the capacitor work normally. The internal circuit connection of the contactor is shown in the figure.

The contactors of 12, 18 and 20 Kvar have two pairs of auxiliary contacts, and the contactors of 30 Kvar have three pairs of auxiliary contacts.

The contactor terminals are covered by an insulating cover and are safe and reliable. The coil terminals are labeled with voltage data to prevent misconnection. The 12, 18, 20Kvar contact terminals are marked with voltage data to prevent misconnection. 12, 18, 20Kvar contactors can be installed with screws, or can be attached to the 35mm standard rail by the bottom slider. The mask has a detachable rectangular white card that the user can use to print the item code.
