Description

technical field [0001] The invention relates to an intelligent control device, more precisely to an intelligent control device for controlling and protecting switching appliances, which belongs to the technical field of motor control. Background technique [0002] Control and Protection Switching Apparatus (CPS) is a new product in low-voltage electrical appliances. As a new major product, its product category code is "CPS", which is the abbreviation of "Control and Protective Switching Device" in English. [0003] The main features of CPS are: realizing integrated and internally coordinated control and protection functions on products with a single structure, which can replace circuit breakers (fuse), contactors, overload (or overcurrent, phase failure) protection relays , starters, isolators and many other traditional separation devices. [0004] Chinese patent No. 01238478.X utility model patent "an integrated control and protection switch" adopts modularization, has iso...
