It is designed for power distribution protection in industrial switchboards and main distribution panels, conforming to EN/IEC 60947-2. Selectivity category B confirms full discrimination with downstream devices, so a fault on a branch feeder does not take the main breaker out. The sensor rating range covers 1250 A, 1600 A, 2000 A, and 2500 A, so the same breaker frame can be adjusted down for a lower-load installation by swapping the sensor module. The H1 performance class means 66 kA Ics at 220/415 V, 440 V, 500/525 V, and 660/690 V AC — the same 66 kA holds at every common distribution voltage, not just the lowest one. The Icw (short-time withstand) is 66 kA for 0.5 s, 1 s, and 3 s, which supports selective coordination with downstream breakers that need time to clear before the main trips. The Icm (making capacity) is 145 kA at all listed voltages, confirming the breaker can close into a bolted fault without contact welding. The 4-pole design with neutral on the right matters for panel layout — the neutral pole is fully rated and switched, not a solid link. The fixed-mount version bolts directly to rails or a base plate, with a connection pitch of 115 mm for busbar alignment. Front and rear connection options on both the upside and downside give flexibility for cable or busbar entry in top-feed or bottom-feed configurations. This breaker is sized for main incoming or large feeder positions in LV switchboards. The fixed-mount format with 537 mm width, 352 mm height, and 300 mm depth fits standard enclosure compartments — verify the gland plate and busbar drop against the 115 mm connection pitch before cutting copper. The IP30 front face is typical for enclosed switchgear; no additional sealing is needed inside a locked panel. The 260 W power dissipation at rated current must be factored into the enclosure ventilation — that is roughly the heat of a small space heater running continuously inside the panel. Rated insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV, covering surge environments typical of industrial mains.","metaTitle":"Schneider Electric LV848073 MasterPact MTZ2 25 H1, 2500 A, 4","metaDescription":"Schneider Electric LV848073 MasterPact MTZ2 circuit breaker, 2500 A rated current, 4 poles, H1 66 kA breaking capacity at 415 V AC.
