Title:
EARTH LEAKAGE BREAKER
Document Type and Number:
Japanese Patent JP2015053197
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain an earth leakage breaker which allows deformation of the terminal of a zero-phase current transformer when connecting the terminal of a zero-phase current transformer for leakage detection and a leakage detection unit, while suppressing short circuit between the terminals of a zero-phase current transformer due to adhesion of soot at the time of breaking.SOLUTION: A receiving part 4b formed in guiding shape for guiding a terminal 2a of a zero-phase current transformer 1 is provided in a case 4 of a leakage detection unit 3 of an earth leakage breaker 101, and a holding part 2b formed to match the guiding shape formed in the receiving part 4b of the case 4 is provided in a terminal part 2 of the zero-phase current transformer 1.
