Technical Field

[0001] The utility model belongs to the technical field of circuit breakers, and specifically relates to an assembly structure of circuit breaker accessories. Background Art

[0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breakers are also called automatic switches, commonly known as "air switches", and also refer to low-voltage circuit breakers. They are electrical appliances that have both manual switch functions and can automatically perform loss of voltage, undervoltage, overload, and short-circuit protection. It can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switches and over-underheating relays, and generally no parts need to be changed after breaking the fault current. It has been widely used.

[0003] As a derivative and supplement of the circuit breaker function, circuit breaker accessories add control means and expand the protection function for the circuit breaker, making the circuit breaker more widely used and more fully protected. Common circuit breaker functional accessories include: undervoltage (or overvoltage) accessories, shunt accessories and auxiliary accessories. At present, the operating mechanism of the circuit breaker used in some scenarios cannot be directly assembled with accessories, which loses some of the extended functions.

[0004] China ZL201710117655.0 A circuit breaker assembly accessory device includes an operating unit and a matching accessory unit.
