The H1 performance tier delivers 66 kA Ics across the full voltage range from 220/415 V up to 660/690 V AC, so the breaker clears faults up to that level and stays operational afterward — no need to replace after a short-circuit event within that rating. Category B selectivity means the breaker is designed to coordinate with downstream devices so only the faulted branch opens, keeping the rest of the bus live. ## Deployment and integration Fixed mounting on rails or a base plate with front and rear connection options on both upside and downside. IP30 protection means it's suited for indoor switchgear enclosures where tools or fingers are the main concern — not washdown environments. Neutral position on the right matters when laying out the busbar order in a 4-pole assembly.","metaTitle":"Schneider Electric LV848183 MasterPact MTZ2 08 H1, 800 A, 66","metaDescription":"LV848183 MasterPact MTZ2 08 H1 fixed circuit breaker, 800 A rated current, 66 kA Ics at 415 V AC, Category B selectivity.
