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
Specifications:
It can be widely used in the relay protection area
Encapsulated with epoxy resin to ensure strong insulation ability
Various mechanical dimensions, highly customer-tailored
Linear output current, high precision
Small volume, light weight, easy for installation
Compact and delicate appearance
Suitable for single-phase electricity meter as well as anti-tampering electricity meter
