Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] Depend on figure 1 combine figure 2 , image 3 As shown, a small circuit breaker with a leakage protector includes a circuit breaker housing. The circuit breaker housing is composed of a circuit breaker housing 1 and a circuit breaker cover 2. A jumper 3 and a lock are installed in the circuit breaker housing 1. Buckle 4 and short-circuit driver 5, described short-circuit driver 5 comprises coil 6 and coil former 7, is provided with the copper sheath 8 with center through hole in the coil former 7, is used to wear steel wire 9 in described copper sheath 8, so One end of the above steel wire 9 corresponds to the lock 4, and the other end of the steel wire 9 is connected to the freely movable terminal cover 10, and the circuit breaker housing corresponding to the terminal cover 10 is provided with a through hole; The housing of the leakage protector is clamped to t...

Abstract

The invention provides a miniature circuit breaker with a current leakage protector, which mainly solves the problem that the traditional miniature circuit breaker with the function of current leakage protection cannot be separated, and is characterized in that: a steel wire (9) is arranged in a short circuit driver (5) in a penetrating manner, and is connected with a cover plate (10) of a wiringterminal; a shell of the circuit breaker is connected with a shell of the current leakage protector in a clamping manner; an abutment lead wire (14) stretches out of the shell of the current leakage protector, and corresponds to an output terminal (17) of the circuit breaker; and an iron core (18) in a current leakage driver (12) corresponds to the cover plate (10) of the wiring terminal. The miniature circuit breaker with the current leakage protector can be separated, and is flexible and convenient.

Description

technical field [0001] The invention relates to a small circuit breaker, which belongs to a small circuit breaker with a leakage protector. Background technique [0002] Miniature circuit breakers refer to low-voltage circuit breakers used on AC 50 / 60Hz rated voltage 230 / 400V and rated current below 63A. They are often used in industrial, commercial, high-rise and residential buildings. Commonly used miniature circuit breakers have overload and short-circuit protection functions but no leakage protection function. Due to the small space in the housing of miniature circuit breakers, it is difficult to meet the use standard by adding leakage protection functional components in the housing. The functional components are Refers to zero-sequence transformers, signal amplification circuit boards, coils, iron cores, etc., often have insufficient tripping force and cause short-circuit non-tripping. Chinese patent ZL99206121.0 discloses a two-wire circuit breaker with a width of 18m...
