The EZCV250H44100: The H breaking-capacity code delivers 100 kA Icu at 220–240 V AC, dropping to 25 kA at 440 V AC. For a 480 V / 277 V panel fed by a transformer with secondary fault current in the 18–22 kA range, this breaker gives comfortable headroom for full selectivity with downstream 10 kA MCBs — you can coordinate without stepping up to a larger frame.
Built-in earth-leakage protection and isolation suitability
This 4-pole variant (4t protected poles, no neutral protection) integrates earth-leakage protection directly into the breaker body — no separate RCCB or Vigi module needed.
Fixed-mount backplate installation with front-connect terminals. The 140 mm width, 165 mm height, and 68 mm depth fit standard EasyPact EZCV250H panel cutouts. Connection pitch is 35 mm per pole. IP20 finger-safe front, IK07 impact rating — acceptable for enclosed distribution boards where personnel access is restricted to qualified electricians.
