It is a 3-pole unit without a Micrologic trip unit, intended for protection applications on 50/60 Hz AC networks up to 600 VAC. Schneider Electric has marked the LV838883 as obsolete. ## Breaking Capacity & Selectivity Planning The L breaking capacity code delivers 200 kA Icu at 240 V AC, 150 kA at 480 V AC, and 100 kA at 600 V AC — all UL 489. That puts this breaker in the high-interrupting tier for large commercial or industrial switchboards. The 30 kA Icw (short-time withstand for 0.5 s per UL 489) supports selective coordination downstream, letting you hold the main closed while a feeder clears a fault. ## Drawout Mount & Panel Integration Drawout mounting means the breaker chassis stays wired to the bus, and the removable cradle slides in and out for maintenance or replacement without disturbing the power connections. The unit measures 17.5 in wide by 17.3 in tall by 16.8 in deep — a standard switchgear cubicle footprint. Base-plate rails support the drawout mechanism; the 4.5 in connection pitch matches typical bus-bar spacing. ## Trip Unit & Protection This listing ships without a Micrologic trip unit — the buyer sources the trip unit separately to match the protection curve (LSIG, LSI, or electronic-only) needed for the downstream load. Integral instantaneous protection is set at 72–88 kA. Maximum breaking time is 9 ms; maximum closing response time is 70 ms.","metaTitle":"Schneider Electric LV838883 MasterPact MTZ2, 1200 A, 3P, Dra","metaDescription":"LV838883 MasterPact MTZ2 circuit breaker, 1200 A, 3-pole, drawout mount, L breaking capacity, 600 VAC, UL 489.
