The Schneider Electric LV839062 is a Masterpact MTZ3 50 HF automatic switch disconnector rated for distribution duty. Breaking capacity hits 100 kA Icu at 254 V AC and 508 V AC, and 85 kA Icu at 635 V AC — all with an external relay per ANSI C37.50. That means it clears fault currents up to 100 kA without upstream coordination failure, sized for high-fault industrial or utility secondary mains. Short-time withstand is 85 kA for 1.5 s (ANSI C37.50), giving downstream breakers time to clear before the main trips — selective coordination is built into the rating, not an afterthought.
