ZCT40 Zero Sequence Current Transformer 40mm for Earth Leakage Relay

Description:

A zero-phase current transformer for use as a leakage current detecting element in a leakage current interrupter in which two magnetic materials of different permeability are provided so as to eliminate a range where the leakage current interrupter is inoperable without lowering its ability to distinguish noise components. The different magnetic materials may be provided as a single core constructed by mixing the materials of different permeability.

Otherwise, the materials can be provided as annually-shaped magnetic pieces stacked one on top of the other. Still further, the materials of different magnetic permeability may be provided as bands of materials interlude to form alternating layers or one of the materials may be provided as at least a portion of a protective case.

Applications:

Electric fire monitoring

Leakage protection system

Electromagnetic relaying protection

Microcomputer protection
