Earth leakage tester function
WebNov 1, 2007 · In the interests of helping to guarantee safer practice and the repeatability of test measurements, IEC 62353 defines two different types of leakage current tests: Equipment Leakage Current. This is regarded as the total leakage deriving from applied parts, enclosure and mains parts combined to real earth. Applied Part Leakage Current. WebTypes based on Poles. According to the poles of circuit breakers, the ELCB is classified into three types. 2-Pole ELCB: it is used for protection in a single-phase system. It has 2 ingoing & 2 outgoing terminals having phase & neutral connections. 3-Pole ELCB: It is used for protection in a three-wire three-phase system.
