CJ19series switching capacitor contactors (hereinafter referred to as contactors) are mainly used in power lines with AC 50Hz or 60Hz and rated working voltage up to 400V, for the use of low-voltage reactive power compensation equipment to input or remove low-voltage parallel capacitors. The contactor is equipped with a surge suppression device, which can effectively reduce the impact of closing surge on the capacitor and suppress over voltage during opening and closing.
The contactor is a direct acting double break point structure, and the contact system is arranged in two layers. The upper layer has three pairs of current limiting contacts and a current limiting resistor to form a surge suppression device. When it is closed, it is first connected for a few miliseconds before the working contact is connected. The permanent magnetic block in the current limiting contact is released under the reaction of the spring, disconnecting the current limiting resistor and allowing the capacitor to work normally. The internal circuit connection diagram of the contactor (see figure).
The contactors of CJ19-25-43 have two pairs of auxiliary contacts, while the contactors of CJ19-63-95 have three pairs of auxiliary contacts. The terminal of the contactor is covered with an insulation cover, ensuring safety and reliability. The coil terminals are marked with voltage data to prevent incorrect connections. The CJ19-25-43 contactor can be installed with screws or can be fastened onto a 35mm standard clamp rail using the slider at the bottom. There is a detachable rectanqular white plaque on the mask, which users can use to print project codes,etc. CJ19-63-95 can be installed with 35mm or 75mm standard clamp rails.
