It is a 3-pole unit configured for line protection with an ETU850 electronic trip unit set for LSI (long-time, short-time, instantaneous) curves. The continuous current rating In is 25 A, with overload protection Ir adjustable from 10 A to 25 A, short-time pickup Isd from 0.6 to 10x In, and instantaneous pickup Ii from 1.5 to 12x In. The class M designation places it in the medium breaking capacity tier within the 3VA2 family, suited for industrial distribution where fault levels are significant but not extreme. ## Deployment context The 3VA2 series is designed for selective coordination in industrial power distribution — the ETU850's LSI curves allow precise time-current discrimination with downstream breakers, reducing the chance of a nuisance trip taking out an entire sub-feed. The neutral conductor protection option (via external current transformer, up to 160% of In) makes this unit adaptable for 4-wire systems where ground-fault or neutral overload monitoring is required — a common need in North American and IEC installations alike.","metaTitle":"3VA2025-5KP32-0DA0 Circuit Breaker, 55kA @ 415V, ETU850 LSI","metaDescription":"Siemens 3VA2025-5KP32-0DA0 IEC frame 100 MCCB, 55kA Icu @ 415V, 25A In, ETU850 LSI protection.
