It carries the MicroLogic 6.2 E electronic trip unit, which provides L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground-fault) protection in a single device — covering the full protection curve without needing separate relays or add-on modules. The breaking capacity is 85 kA Icu at 500 V AC 50/60 Hz per IEC 60947-2, stepping down to 80 kA at 525 V and 75 kA at 690 V. That puts it in the HB1 class — high-interrupting for industrial distribution where fault currents can exceed 50 kA. The 4-pole design with neutral on the left suits three-phase plus neutral distribution in panelboards feeding mixed single-phase and three-phase loads. ## What the MicroLogic 6.2 E trip unit means for selectivity It logs time-stamped histories, event tables, demand current and power, power quality data, and protection/alarm settings — data that a facility engineer can pull for predictive maintenance or post-fault analysis without adding a separate power monitor. If the load re-energises while the conductor is still hot, the trip curve shifts to prevent re-closing into a still-overloaded condition — a detail that matters for motor circuits or high-inertia loads that draw inrush after a brief interruption. ## Mounting and integration into a switchboard The 35 mm connection pitch matches standard busbar systems, and the 161 mm height by 140 mm width by 86 mm depth fits within a typical distribution section without crowding adjacent breakers. The IK07 impact rating confirms it withstands a 2 J impact, enough for accidental tool drops during maintenance.","metaTitle":"Schneider Electric C25V46E100 ComPacT NSX 100A 4P MCCB, Micr","metaDescription":"Schneider Electric C25V46E100 ComPacT NSX 250A frame MCCB, 100 A rated, 4-pole, MicroLogic 6.2 E trip unit with LSI+G protection. 85 kA Icu at 500 V AC.
