It belongs to the H2V performance class, delivering 100 kA ultimate breaking capacity (Icu) at 440 V AC — the same figure holds for service breaking (Ics), so it clears a fault and is ready to reclose without derating the installation. The making capacity (Icm) is 220 kA at 440 V, meaning it can close onto a bolted fault without welding contacts. Short-time withstand (Icw) is 100 kA for 1 s, which supports full selectivity with downstream breakers in a distribution panel. This is a Category B breaker per IEC 60947-2, designed for power distribution protection in switchboards and industrial main feeders. The drawout chassis lets you rack the breaker out for maintenance or replacement without disturbing the bus connections — a standard requirement for low-voltage main and tie positions. Because the Ics equals the Icu at both 220/415 V and 440 V, you don't lose capacity after a fault — the breaker stays in service without needing immediate replacement. That matters for critical feeders where downtime for breaker swap is unacceptable. The making capacity of 220 kA peak ensures the contacts close against the full asymmetrical fault current without arcing damage. Short-time withstand (Icw) of 100 kA for 1 s supports zone-selective interlocking and cascading schemes. With a maximum break time of 25 ms and closing response of 70 ms, this breaker coordinates cleanly with upstream and downstream devices in a selective coordination study. Dimensions are 441 mm wide × 439 mm high × 403 mm deep. The drawout mechanism mounts on rails or a base plate; connection pitch is 115 mm. Both front and rear connection are supported on the upside and downside, giving flexibility for cable or busbar entry in a switchboard lineup. Altitude derating applies above 2000 m. The breaker ships without a control unit — the Micrologic trip unit is ordered separately based on the protection profile needed (LSIG, LS, etc.). Sensor ratings of 400 A, 630 A, and 800 A are listed, meaning the breaker frame accepts interchangeable rating plugs to match the load without changing the power poles.","metaTitle":"LV846170 MasterPact MTZ2 800A Circuit Breaker, 100 kA","metaDescription":"Schneider Electric LV846170 MasterPact MTZ2 drawout circuit breaker, 800 A rated, 100 kA breaking at 440 V.

The H2V 100 kA variant is the high-breaking-capacity option; stepping to N2 (65 kA) or S2 (150 kA) changes the fault-interruption ceiling.
