The Schneider Electric EZCV250H3175 is a 3-pole molded case circuit breaker from the EasyPact EZCV250H series, fitted with a TM-D thermal-magnetic trip unit rated at 175 A at 40 °C. This is the distribution-grade variant with earth-leakage protection integrated, intended for fixed-mount backplate installation in panelboards and switchboards. Breaking capacity is the headline selector here: 100 kA Icu at 220–240 V AC, 36 kA at 380–415 V, and 25 kA at 440 V — all per IEC 60947-2. That H breaking-capacity code means it handles high prospective fault currents at the lower distribution voltages common in commercial and light industrial mains, so it can be applied upstream without a current-limiting fuse for coordination.
The 105 mm width and 165 mm height fit standard panel cutouts for the EZCV250H frame. IP20 finger-safe enclosure per IEC 60529 and IK07 impact resistance per EN 50102.
Protection and Duty
Earth-leakage protection is onboard, so this single device covers overcurrent and ground-fault in one footprint — a space-saving choice compared to a separate RCCB plus MCCB combination.
