Product details

Overview

The EZC400N3320 is a Schneider EasyPact EZC400N 3-pole molded-case circuit breaker rated for 400 A switching current at 440 V AC. It carries a TM-D thermal-magnetic trip unit set to 320 A at 50 °C, fixed-mount construction, and IP20 finger-safe enclosure. This model is an active production part, available through current distribution channels.

Schneider lists the EZC400N3320 as an active product with no announced end-of-life. For a BOM freeze or line-down need, an RFQ is the fastest path to confirm current lead time and available quantity. The part is sourced through standard distribution; no last-time-buy window applies.
