It ships as a single unit (one per package) without a Micrologic trip unit. The kit includes the breaker frame, the fixed base plate with rails, and the push-button control interface. No trip unit, no plug-in accessories — those are separate line items. If you are kitting a replacement for a line-down situation, verify the trip unit order code alongside this frame to avoid a second trip. ## Breaking capacity — what the H3 code delivers The H3 breaking capacity code means this breaker can interrupt 100 kA Icu at 254 V AC, 100 kA Icu at 508 V AC, and 85 kA Icu at 635 V AC (all per ANSI C37.50). The rated short-time withstand current (Icw) is 85 kA for 0.5 s — that is the fault current the frame can carry without damage during a delayed trip coordination scheme. The integral instantaneous protection triggers between 171 kA and 209 kA, covering the high-end fault range. Maximum break time is 25 to 30 ms; closing response is 70 ms max. ## Physical fit — panel and enclosure integration Fixed-mount on a base plate with rails. Dimensions: width 30.2 in (767 mm), height 13.9 in (352.2 mm), depth 11.7 in (297.7 mm). Connection pitch is 9.06 in (230 mm) between phases. The breaker is designed for ANSI-style switchgear lineups — the fixed version bolts directly to the bus, not a draw-out cassette. For a panel OEM or MRO planner, the depth is the critical dimension for enclosure depth: 297.7 mm means a standard 400 mm deep enclosure leaves clearance for rear connections and cable bending radius.","metaTitle":"LV839034 MasterPact MTZ3 6000A 3P Fixed Circuit Breaker, H3","metaDescription":"Active LV839034 MasterPact MTZ3 6000A 3-pole fixed circuit breaker, H3 breaking capacity (100 kA Icu at 254 V AC).
