CJ19 Series AC Contactor for Switching Power Capacitor

The Geyue Electric CJ19 Series AC Contactor for Switching Power Capacitor holds a vital position in the low voltage reactive power compensation cabinet, being specifically engineered to accurately switch on or switch off the Geyue Electric BSMJ series or BSMJ(Y) series low voltage shunt capacitors. This CJ19 Series AC Contactor for Switching Power Capacitor is ingeniously furnished with an advanced inrush current restraint device. Such a device proves highly efficient as it can notably mitigate the closing impact, thus minimizing potential harm and guaranteeing smooth functioning. Moreover, CJ19 Series AC Contactor for Switching Power Capacitor is able to curb the overvoltage that emerges during the breaking process, offering an additional level of protection and stability to the entire system. This functionality not only boosts the reliability and safety of the equipment but also facilitates the efficient and stable operation of the low voltage reactive power compensation cabinet in diverse applications.

Geyue Electric designed the CJ19 Series AC Contactor for Switching Power Capacitor in the form of a direct-acting double-break structure. The contact system is arranged in two distinct layers. Specifically, the three pairs of contacts in the upper layer, in combination with the current-limiting resistance, form the greatly effective inrush current suppression device. When the switch is actuated for closure, the upper three pairs of contacts are connected initially. After a brief period of a few milliseconds, the working contact is securely established. The permanent magnetic block within the current-limiting contact is released under the reactive force of the spring. Simultaneously, the current-limiting resistance is disconnected, thereby enabling the power capacitor to operate in a normal and stable manner. The CJ19 Series AC Contactor for Switching Power Capacitors with the conventional free air thermal current of 25A, 32A and 43A have two pairs of auxiliary contacts, and the ones with the conventional free air thermal current of 65A, 85A and 95A have three pairs of auxiliary contacts.

Geyue Electric makes every terminal of the CJ19 Series AC Contactor for Switching Power Capacitor wrapped with an insulating cover, which effectively prevents any potential electrical hazards and ensures a safe and reliable connection process. Such a design feature significantly enhances the overall safety and performance of the contactor system. Geyue Electric claims considerable thoughtfulness by marking the voltage on the coil terminal of the CJ19 Series AC Contactor for Switching Power Capacitor.

This precautionary measure is taken to effectively avoid the user from making incorrect line connections during the wiring process. The three models of contactors, CJ19-25, CJ19-32, and CJ19-43, offer users flexibility in installation. They can be securely installed either with screws or by utilizing the contactor buckle on the 35mm standard guide rail. However, the three models of contactors, CJ19-63, CJ19-85, and CJ19-95, have a more specific installation requirement. They can only be firmly mounted on the 35mm or 75mm standard guide rail through the contactor buckle.
