Abstract

The invention discloses a novel multifunctional AC contactor, which relates to the field of electrics. The 95A novel multifunctional AC contactor comprises an AC contactor; the AC contactor comprisesa contact system, a connecting support system, an arc extinguishing system, an electromagnetic system, amounting base, a contact protection device and independent wiring terminal modules; the contactsystem, the electromagnetic system and the contact protection device are arranged at the top of the mounting base; the arc extinguishing system is fixedly connected with the contact system; the connecting support system is arranged at the top of the contact system; and the two independent wiring terminal modules are arranged on the two sides of the contact protection device. The 95A novel multifunctional AC contactor is small in size, modular in design, multiple in mounting modes, high in protection grade, high in electrical safety performance, high in expandability, various in wiring types, novel in overall appearance modeling, and capable of remotely switching on and switching off circuits of AC-3 use types, rated working voltage 380V and rated working current to 95A.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a novel multifunctional AC contactor. Background technique [0002] With the increasing load density of power distribution system and the market demand for miniaturization of power distribution cabinets, small and high-current electrical components are required to meet these market demands. [0003] At present, the domestic AC-3 use category and the rated working current up to 95A when the rated working voltage is 380V have the following defects: large volume, low utilization of box space; the main and auxiliary circuits are designed on the same floor, and the circuit wiring layout is not clear , The coil control loop wiring is designed at the bottom of the main and auxiliary loop wiring. When the AC contactor is installed vertically, the user wiring is inconvenient, and the protection performance, electrical safety performance, and scalability are poor. Contents of the inv...
