The H10 performance class delivers 50 kA Ics (service breaking capacity) at 1150 V AC 50/60 Hz, and 50 kA Icw for up to 3 s, so it safely clears high-energy faults in industrial distribution without cascading upstream. Category B selectivity (per EN/IEC 60947-2) means it coordinates with downstream breakers to isolate only the faulted branch — critical for maintaining power to the rest of the plant during a short circuit. ## Deployment context Fixed-mount on rails or base plate, with rear connection top and bottom — typical for switchboard or MCC lineup integration where the breaker is bolted in rather than draw-out. The 537 mm width, 352 mm height, and 300 mm depth fit standard cubicle compartments; the 115 mm connection pitch matches common busbar drilling patterns. IP30 protection means it is enclosed in a panel or cabinet — not for outdoor or washdown exposure. Electrical durability is 500 cycles at rated voltage; mechanical durability is 25,000 cycles with periodic preventive maintenance. The 170 W power dissipation at rated current should be factored into enclosure thermal calculations.","metaTitle":"Schneider Electric LV846553 MasterPact MTZ2 1600A Circuit Br","metaDescription":"Schneider Electric LV846553 MasterPact MTZ2 fixed circuit breaker, 1600 A rated current, 50 kA breaking capacity at 1150 V AC.
