The invention relates to an earth leakage circuit breaker with an extended line, which comprises a terminal, a leakage release, a base, an electromagnetic system, a handle operating mechanism, a static contact, a movable contact, a conductive system, a clapboard device, a magnetic ring, a bimetallic system, a circuit board, an arcing shield and a cover, wherein the leakage release is arranged at the electromagnetic system, the lower part of the arcing shield is provided with the circuit board, a zero wire pole feeding terminal is connected with a zero-wire extended line, the same side of the zero-wire extended line is provided with an earth-wire extended line, and the earth-wire extended line is connected with the circuit board. The earth leakage circuit breaker has small volume, thus more breakers can be installed in a distribution box with the same width, and the use ratio of the space of the distribution box is improved. Meanwhile, the zero-wire extended line can be directly connected to a zero-wire power supply bonding post in the distribution box, which is simple and convenient and greatly improves the installing efficiency. The earth-wire extended line of the earth leakage circuit breaker can protect a zero wire effectively when the zero wire goes wrong, and thus, the earth leakage circuit breaker is more safer to use.
Description
technical field [0001] The invention relates to the field of circuit breakers, in particular to an 18mm wide circuit breaker. Background technique [0002] Leakage protection circuit breaker includes partition device, terminal, base, electromagnetic system, handle operating mechanism, static contact, moving contact, conductive system, leakage detection sensing system, double gold system, circuit board, arc extinguishing cover and cover, traditional The leakage protection circuit breaker with a width of 36mm usually installs components such as circuit boards and leakage releases on the back side of the partition device. Traditional leakage protection circuit breakers with a width of 18mm usually install components such as circuit boards and leakage releases on the circuit breaker. One end of the circuit breaker increases the volume of the circuit breaker, and it is inconvenient to connect the neutral line of the leakage protection circuit breaker directly to the neutral line ...
