The 4-pole design with neutral on the left is common for three-phase + N distribution. Selectivity category B means it coordinates with downstream breakers to isolate only the faulted branch — a key requirement for maintaining uptime on a critical bus. ## Breaking capacity and what that means for your panel The H2V performance level delivers 100 kA Ics at 415 V AC and 440 V AC. ## Integration and mounting constraints Fixed mounting on rails or a base plate. The 537 mm width, 352 mm height, and 300 mm depth — plus the 115 mm connection pitch — determine the panel cutout and busbar layout. Front or rear connections on both the line and load sides give flexibility for cable entry direction. IP30 means no protection against water ingress; install inside a switchboard enclosure rated for the environment. Derate above 2000 m altitude. Suitability for isolation per EN/IEC 60947-2 means it provides a visible break and meets the safety requirements for disconnecting a circuit.","metaTitle":"Schneider Electric LV846182 MasterPact MTZ2 1250 A Circuit B","metaDescription":"Schneider Electric LV846182 MasterPact MTZ2 fixed circuit breaker, 1250 A rated current, 100 kA breaking capacity at 440 V AC.
