The H3 rating delivers 100 kA Icu at 508 V AC and 85 kA Icu at 635 V AC per ANSI C37.50 — meaning it can safely interrupt fault currents up to those levels at the respective voltages, which is the figure that governs main-breaker coordination studies. The 85 kA Icw short-time withstand current for 0.5 s (ANSI C37.50) tells you it holds through delayed tripping sequences for selective coordination downstream. This breaker ships without a Micrologic trip unit, so the trip curve is set by the unit you install separately. ## Deployment context Fixed-mount base-plate installation on rails — the 39.2 in (996.3 mm) width and 13.9 in (352.2 mm) height define the panel cutout and bus-bar takeoff spacing. Neutral is on the left; connection pitch is 9.06 in (230 mm). The 11.7 in (297.7 mm) depth fits standard switchgear cubicle depths, but verify gland-plate clearance for the rear bus connections. At 5000 A continuous, bus-bar sizing and ventilation are the limiting factors, not the breaker footprint.","metaTitle":"Schneider Electric LV839032 MasterPact MTZ3 5000A 4P Circuit","metaDescription":"LV839032 MasterPact MTZ3 circuit breaker, 5000 A rated, 4-pole, fixed mount, H3 breaking capacity (100 kA Icu at 508 V AC).
