The Schneider Electric EZC630H4600N is a 4-pole molded case circuit breaker from the EasyPact EZC630H series, rated 630 A at 40 °C and 600 A at 50 °C. The TM-D thermal-magnetic trip unit provides overload and short-circuit protection, with a fixed magnetic tripping threshold of 4000 A. The 70 kA Icu at 220/230 V AC gives additional headroom on lower-voltage distribution. This is a Category A circuit breaker (no intentional short-time delay), suited for distribution applications where selectivity is achieved by current grading rather than time delay. The IP20 finger-safe enclosure and IK07 impact resistance are standard for panel-mounted MCCBs — it's designed for fixed backplate mounting with front-front connections (both line and load sides connect from the front).
Compliance documentation covers JIS C8201-2-2, EN/IEC 60947-2, and GB/T 14048.2. The breaker is certified for isolation per IEC 60947-2, and the positive contact indication gives a visual confirmation of contact position.
Mounts on a backplate with a fixed mounting mode — no DIN rail adapter. The 185 mm width, 255 mm height, and 140 mm depth fit standard distribution panel cutouts; the 45 mm pole pitch is consistent with other EasyPact EZC frames. Front-front connections simplify busbar routing in switchboards, and the toggle control provides a clear on/off/ tripped position. The 4000 A magnetic trip point is fixed — no adjustment. For selectivity studies, the electrical endurance is 3000 cycles at 415 V AC (Category A), and mechanical endurance is 10,000 cycles. The breaker ships as a single piece, without earth-leakage protection module (add external RCD if needed).
