Rear connection top and bottom, so it's built for switchboard bus-stack integration, not standalone panel mounting. Category B selectivity means this breaker is designed for full discrimination with downstream devices — a fault on a branch won't take the main feeder out. The Icw short-time withstand is 100 kA for up to 3 seconds, which gives downstream breakers time to clear before the main trips. That's the spec that matters for coordination studies in a distribution board. Rated insulation voltage is 1000 V AC, operational voltage 690 V AC. Impulse withstand at 12 kV. ## Physical fit Fixed mounting on rails or base plate. Width 997 mm, height 352 mm, depth 300 mm. Connection pitch 230 mm. That depth is the overall front-to-back dimension including the mechanism — verify cabinet depth before specifying. Neutral position is right. ## Standards and documentation Compliant with EN/IEC 60947-1, EN/IEC 60947-2, and Annex H for selective coordination. Also meets IEC 61557-12 for power metering. Suitability for isolation confirmed per EN/IEC 60947-2. IP30 protection — not for washdown, but fine in a clean switchroom.","metaTitle":"Schneider Electric LV848103 MasterPact MTZ3 4000 A Circuit B","metaDescription":"Schneider Electric LV848103 MasterPact MTZ3 4000 A fixed circuit breaker, H2 150 kA at 415 V AC, 4P, rear connection.
