Overview
The EZAUVR277AC is a Schneider EasyPact EZC undervoltage release (MN type) rated 277 V AC, designed for the EZC400 frame. It trips the breaker when supply drops below 0.35 Un and re-closes above 0.85 Un, with a 50 ms response time. Schneider has discontinued this part.
Lifecycle & availability
Schneider lists the EZAUVR277AC as discontinued with no direct successor. For a BOM freeze or line-down need, sourcing runs through surplus and broker channels; an RFQ is the fastest path to confirm availability and lead time. The closest functional peer is the EZAUVR110AC, which uses 130 V AC coil voltage rather than 277 V AC — verify coil voltage compatibility before substituting.
