Problems solved by technology

This fire-fighting type control and protection switch operating mechanism has the following disadvantages: (1) it cannot be manually controlled on the spot, that is, the on-off control of the main circuit cannot be realized through the control handle, and it can only be controlled by buttons on the spot or remotely. The use and maintenance of the product brings a lot of trouble
(2) The wiring lines are relatively cumbersome, which reduces the overall reliability of the product

Description

1. Technical field [0001] The invention belongs to a control and protection switching device in the field of low-voltage electrical appliances, more precisely, the invention is an operating mechanism of a KBO control and protection switching device with a fire-fighting function. 2. Background technology [0002] "Control and Protective Switching Appliance" (Control Protective Device) 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. 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 discrete components. KB0 is the first generation of CPS products. ...
