The Schneider Electric LV432575 is an external neutral current transformer (ENCT) for 3-pole ComPacT NSX400 and NSX630 breakers fitted with a MicroLogic 5 or 6 trip unit. It protects the distributed neutral of the installation, sensing from 400 A to 630 A. The sensor connects to the trip unit by a shielded twisted pair, up to 10 m long, with a 0.4-1.5 mm² cross-section.
Install this 400-630 A sensor on 3-pole NSX400/630 breakers; for lower current frames use LV429521 (NSX100, 25-100 A) or LV430563 (NSX160/250, 150-250 A) instead. All three sensors share the same MicroLogic 5/6 wiring method, so only the current band differs between them.
