Abstract

The invention provides an electronic type leakage circuit breaker, which comprises a shell. A partition plate arranged in the shell divides the shell into two layers of cavities. The two layers of cavities are composed of a first cavity and a second cavity. The first cavity is used for placing an L-pole circuit breaker module. The second cavity is used for placing an N-pole circuit breaker module and a leakage protection module of the electronic type leakage circuit breaker. Therefore, the internal space of a product is fully utilized. Meanwhile, through improving the rated current, the high temperature rise and other unqualified phenomena can be avoided. Therefore, the safe current-carrying capacity of the electronic type leakage circuit breaker is ensured, and the rated current of the electronic type leakage circuit breaker reaches 63A.

Description

technical field [0001] The invention belongs to the field of low-voltage electrical appliances, and relates to an electronic leakage circuit breaker, in particular to a 1P+N integrated electronic leakage circuit breaker. Background technique [0002] 1P+N electronic leakage circuit breaker is a small circuit breaker, including an L pole (phase line) breaking unit and an N pole (neutral line) breaking unit, mainly suitable for AC 50Hz / 60Hz, rated current up to 63A In the line, it has leakage, short circuit and overload protection functions. The existing 1P+N electronic leakage circuit breaker has two structural forms: assembled type and integral type. Among them, the 1P+N electronic leakage circuit breaker with assembled structure is composed of an independent 1P circuit breaker (1 module wide) and An independent leakage trip unit (generally wider than 18mm, that is, greater than one module width) is assembled, and the rated current can reach 63A, but the assembled module wi...
