It carries UL 489 listing and delivers 65 kA Icu at 240 V AC, 50 kA Icu at 480 V AC, and 50 kA Icu at 600 V AC — the interrupting rating you need to match the available fault current at your service entrance or distribution panel. The 35 kA Icw (0.5 s per UL 489) gives you short-time withstand for selective coordination downstream. Mechanical durability is rated at 10,000 cycles (ANSI C37.50), electrical durability at 1,000 cycles — figures that tell you this breaker is built for main or feeder duty where you cycle it infrequently but need it to clear faults reliably. The integral instant protection range of 81–99 kA means the magnetic trip acts fast on high faults, while the 25–30 ms maximum breaking time keeps arc energy contained. Fixed mounting on base plate rails, with a connection pitch of 70 mm. Dimensions: width 276.2 mm, height 300.5 mm, depth 209 mm. That depth (8.2 in) matters when you're laying out the gland plate or door clearance — it's a standard drawout-equivalent footprint for the MTZ1 frame.","metaTitle":"Schneider LV839108 MasterPact MTZ1 800A 3P Fixed Circuit Bre","metaDescription":"Schneider LV839108 MasterPact MTZ1 circuit breaker, 800 A rated, 3 pole, fixed mount, H breaking capacity, 65 kA Icu at 240 V, UL 489 listed.
