Integrator's spec recap — EZCV250H44175
The Schneider Electric EZCV250H44175 is a 4-pole molded case circuit breaker from the EasyPact EZCV250H series, rated 175 A at 40 °C with a thermal-magnetic TM-D trip unit. It delivers a breaking capacity of 100 kA Icu at 240 V AC, 36 kA at 415 V, and 25 kA at 440 V AC, all per IEC 60947-2 — enough for high-fault distribution panels. The fixed-mount, front-connect design suits backplate installation; the 140 mm width and 68 mm depth fit standard enclosure cutouts.
The 4-pole configuration protects all three phases plus the neutral (though neutral protection is not set — it's a straight-through pole).
Deployment context — distribution board integration
The fixed-mount, backplate-supported design with front connections (both upside and downside) is typical for panelboard or switchboard installation. The 35 mm connection pitch matches standard busbar spacing. The toggle control and positive contact indication give clear visual status.
