This is a 4-pole unit with front-connect terminals, rated for distribution duty per EN/IEC 60947-2. The trip unit provides L (long-time overload), S (short-time short-circuit), I (instantaneous), and G (ground-fault) protection — the G function is the distinguishing feature here, making this breaker suitable for systems where ground-fault coordination is required, such as on IT or TN-S networks with sensitive earth-leakage detection. Rated 100 kA Icu at 500 V AC, 525 V AC, and 660/690 V AC (50/60 Hz) per IEC 60947-2. That is a consistent high-interrupting rating across the voltage band — not a derated figure at the top end. For a site electrical engineer coordinating a distribution board, this HB2 (100 kA at 690 V) grade means the breaker can be placed upstream of lower-rated devices without exceeding its short-circuit withstand. The utilisation category is A, so it is not intended for reverse-feed or bidirectional current flow applications without manufacturer guidance. Mounts on a backplate (not DIN rail) — the 161 mm height, 140 mm width, and 86 mm depth fit standard ComPacT NSX cutouts. Neutral is on the left. ## Durability and metering capability Mechanical durability is 20,000 cycles; electrical durability is 20,000 cycles at 440 V at half-rated current, 10,000 cycles at full 440 V, and 5,000 cycles at 690 V full load. The MicroLogic 6.2 E includes an energy meter function and communicates time-stamped event histories, maintenance indicators, power quality data, and demand values — useful for a facility engineer tracking load profiles without a separate power meter.","metaTitle":"Schneider Electric C25W46E250 ComPacT NSX 250A, 100kA 690V","metaDescription":"Schneider Electric C25W46E250 ComPacT NSX250HB2 molded case circuit breaker. 250 A rating, MicroLogic 6.2 E trip unit with ground fault protection. 100 kA Icu at 690 V AC.
