Title:
GROUND-FAULT CIRCUIT INTERRUPTER
Document Type and Number:
WIPO Patent Application WO/2011/045892
Kind Code:
A1
Abstract:
Disclosed is a ground-fault circuit interrupter that has been developed in a manner so as to be forcibly set to high speed operation at the same time that detection sensitivity is set from low sensitivity to high sensitivity by means of a mechanical setup with a simple configuration. In the ground-fault circuit interrupter, when a sensitivity changeover setting unit (120) is set to high sensitivity (30mA) by operating the sensitivity changeover extending slide switch (171b) of a constraint setting unit (170), a projecting part (171a) pushes out a time-delay changeover extending slide switch (172b), and a time-delay changeover setting unit (150) is forcibly set to high speed operation (0ms time delay).
