It carries a H2V performance class: 100 kA breaking capacity at 415 V AC, 50/60 Hz. This is a Category B breaker (selectivity type), designed for power distribution protection in switchgear assemblies. The Ics (service breaking capacity) is the same 100 kA, so after clearing a fault at full rating it can be reclosed and continue service, not just be replaced. The Icw of 100 kA for 1 second gives coordination flexibility: downstream breakers can delay their trip to achieve selectivity, knowing the MTZ2 holds the fault for a full second. The 12 kV impulse withstand (Uimp) confirms it meets the insulation coordination for 1000 V class systems. Isolation suitability per EN/IEC 60947-2 means it provides a visible break gap — no need for a separate disconnect switch upstream. ## Integration into the switchgear assembly Drawout mounting means the breaker mechanism slides into a fixed cradle — the 441 mm width, 439 mm height, and 403 mm depth define the cradle cutout and clearance for arc chutes. Connection pitch is 115 mm between phases. The IP30 enclosure protects against tools and wires during panel work but is not sealed for washdown — this lives in a dry indoor switchgear lineup. The LV846172 is designed and tested to EN/IEC 60947-1 (general rules), EN/IEC 60947-2 (circuit-breakers), EN/IEC 60947-2 Annex H (selectivity), and IEC 61557-12 (power metering). These are the core standards for industrial low-voltage switchgear. The breaker carries a CE mark for the European market. Compliance documentation (declaration of conformity, test certificates) is available from Schneider Electric's document portal using the LV846172 order code.","metaTitle":"Schneider Electric LV846172 MasterPact MTZ2 3P 1250A Drawout","metaDescription":"Schneider Electric LV846172 MasterPact MTZ2 circuit breaker, 3 poles, 1250 A rated current, H2V 100 kA at 415 V AC.
