It's a Category B breaker (EN/IEC 60947-2), meaning it provides selective coordination with downstream devices — the fault stays local and the rest of the bus keeps running. The drawout chassis lets you rack the breaker out for maintenance or swap without disturbing the power connections, which is standard for switchgear lineups where uptime matters. ## Breaking capacity and withstand Rated service breaking capacity (Ics) is 100 kA at 220/415 V and 440 V AC, 85 kA at 500/525 V and 660/690 V AC — that's the fault current it can clear and still be used again. Short-time withstand (Icw) is 85 kA for 0.5 s or 1 s, 50 kA for 3 s, which covers delayed-tripping coordination in a selective system. Making capacity (Icm) hits 220 kA at 415/440 V, so it can close onto a bolted fault without welding contacts. ## Physical footprint and mounting Drawout version with chassis: 403 mm deep, 556 mm wide, 439 mm high. Without chassis: 300 mm deep, 493 mm wide, 300 mm high. Mounts on rails or a base plate. Connection pitch is 115 mm. IP30 protection (EN 60529) means it's enclosed against tools and wires >2.5 mm, typical for indoor switchgear. ## Durability and operating conditions Mechanical durability is 25,000 cycles with periodic preventive maintenance. Electrical durability: 10,000 cycles at 440 V or 690 V AC (EN/IEC 60947-2), 6,000 cycles in AC-3 motor-switching duty (EN/IEC 60947-3). Maximum breaking time is 25 ms, closing response 70 ms. Power dissipation is 100 W at rated current — factor that into enclosure ventilation.","metaTitle":"Schneider Electric LV848426 MasterPact MTZ2 800A Drawout Cir","metaDescription":"Schneider Electric LV848426 MasterPact MTZ2 800A drawout circuit breaker, H2 100 kA at 415 VAC, 4P, current production.
