The Schneider Electric EZCV250N44080 is a 4-pole EasyPact EZCV250N moulded-case circuit breaker rated 80 A at 40 °C with a TM-D thermal-magnetic trip unit. It delivers 20 kA Icu at 440 V AC (50/60 Hz) per IEC 60947-2, with a Category A utilization class — meaning it's not intended for selective coordination downstream but is fine for branch-circuit protection in distribution panels.
Breaking capacity — what the N code means
The N breaking-capacity code on this EasyPact EZCV250N gives 20 kA Icu at 440 V AC, 25 kA at 380–415 V, and 85 kA at 220–240 V. For a 440 V distribution board, 20 kA Icu is enough for most secondary feeders; if your upstream transformer can push more fault current, you'd step up to the H or L code in the same frame size.
Connection pitch is 35 mm, so it fits standard busbar systems. The breaker measures 165 mm high × 140 mm wide × 68 mm deep — check your enclosure depth if you're retrofitting into a shallow panel. IP20 finger-safe terminals; IK07 impact resistance means it survives a 2 J hammer blow during installation.
Complies with JIS C8201-2-2, EN/IEC 60947-2, GB/T 14048.2, and EN/IEC 60947-1. Pollution degree 3 and suitability for isolation per IEC 60947-2 are the key approvals for an industrial panel builder.
