The breaking capacity code means 100 kA Icu at 240 V AC and 65 kA Icu at 480 V AC under UL 489, which covers most industrial service-entrance and distribution panel applications where fault current runs high. The 3-pole fixed-mount construction bolts onto a base plate with rails (70 mm connection pitch), so it lands in a switchboard or a dedicated enclosure — not a DIN-rail panel. No Micrologic trip unit ships with this order code; the buyer sources the trip unit separately to match the protection curve (LSIG, LSI, or electronic) needed for the downstream load. ## Deployment context Fixed-mount breakers like this one go into switchboards, motor control centers, or dedicated distribution enclosures — not DIN-rail cabinets. The 209 mm depth, 276 mm width, and 300 mm height mean the enclosure must allow front-access cable termination and sufficient clearance for arc-flash boundaries. The 70 mm pole-to-pole pitch matches standard bus-bar spacing for 1600 A class switchgear. ## Performance and protection Rated short-time withstand current (Icw) is 10 kA for 0.5 s under UL 489 — this breaker coordinates with downstream devices that clear faster than half a second, so it holds in during a fault without welding contacts. The integral instantaneous protection trips between 19.8 and 24.2 kA, which is the magnetic-only backup if the electronic trip unit is absent or fails. Maximum breaking time is 9 ms, and closing response is 50 ms. Mechanical endurance is 10,000 cycles, electrical endurance 1,000 cycles per ANSI C37.50 — typical for a primary distribution breaker that sees infrequent switching.","metaTitle":"Schneider LV839113 MasterPact MTZ1 1600A 3P Fixed, 100kA Icu","metaDescription":"LV839113 MasterPact MTZ1 circuit breaker, 1600 A at 40 °C, 3-pole fixed mount, 100 kA Icu at 240 V AC, UL 489.

A direct alternative within the same family would be the same frame with a different breaking capacity code (e.g., L2 or H1 for higher Icu) or with an integrated Micrologic trip unit (different order code). No pin-compatible drop-in exists because the trip unit is ordered separately."},{"question":"What compliance documentation does Schneider provide for LV839113?","answer":"The LV839113 carries a UL 489 listing.
