It carries a 200 kA Icu at 240 V AC, 150 kA Icu at 480 V AC, and 100 kA Icu at 600 V AC under UL 489 — meaning it can safely interrupt a fault up to those levels without the arc jumping upstream. The ArcBlok design contains and extinguishes the arc inside the cassette, which is what lets it hit those numbers in a standard panel footprint. Drawout mounting means the cassette slides out of its chassis cradle for inspection or replacement without pulling main bus bars — a real time-saver when you're coordinating a line-down window. The push-button control on the front gives you local open/close without reaching for a separate actuator. This is a distribution-class switch disconnector for the main incoming or a large feeder in a UL 489 panelboard or switchboard. The drawout chassis bolts to the enclosure frame; the cassette slides in on rails. Physical envelope is 17.5 in wide by 17.3 in tall by 16.8 in deep — that's the cassette plus the cradle, so plan your cutout and bus spacing accordingly. The 4.5 in connection pitch matches standard bus-bar centers for 2500 A class gear.","metaTitle":"LV839161 Masterpact MTZ2 25 HB Drawout, 2500 A, 200 kA","metaDescription":"Schneider Electric LV839161 Masterpact MTZ2 25 HB drawout switch disconnector, 2500 A rated at 40 °C, 200 kA Icu at 240 V AC UL 489.
