The contactor is direct-action type with double-break contact construction. Its system is divided into two layers: upper and lower. In the upper layer, there is an inrush current suppression device composed of three pairs of precharge contacts and a closing resistor. When the switch is closed, the device is first engaged, then after several milliseconds, the working contacts are engaged. The permanent magnetic latch of the precharge contacts is released by spring reaction, and the closing resistor is bypassed, so the capacitor operates normally. Contactors of 12, 18, 20kvar have two pairs of auxiliary contacts, and contactors of 30kvar have three pairs of auxiliary contacts.
Terminals of the contactors are protected by insulation covers, making them safe and reliable to use. Voltage data is marked at the terminals to avoid wrong connections. 12, 18, 20kvar contactors can be mounted not only by screws but also by clipping the bottom sliders onto 35mm standard tracks. On the front screen, there is a rectangular white plate which can be torn off. Users can print the item code on this plate.
