Schneider Electric LV432575 External Neutral Current Transformer

LV432575 is Schneider Electric’s external neutral current transformer (ENCT) accessory for ComPact NSX400/630 three‑pole circuit breakers equipped with Micrologic 5 or 6 trip units. This ENCT option provides neutral‑current sensing for NSX installations and is specified for a 400 A to 630 A primary current range on NSX400/630 3P devices. The component is a 3‑pole ENCT listed across Schneider Electric regional product pages and distributor datasheets under LV432575 (with some listings referring to S432575). It sits within the Compact NSX family as a dedicated neutral‑current monitoring accessory used to support protection features that rely on precise neutral data in the trip logic, helping coordinate protective schemes without altering the main current path.
