It carries the ETU860 electronic trip unit, which gives you adjustable long-time delay (tr) from 0.5 to 25 seconds and short-time delay (tsd) from 0.05 to 0.5 seconds, with the Ir max set at 800 A. The interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — numbers that tell you this breaker is sized for high-fault-current main or feeder duty in an industrial distribution panel. The 800 A frame and the 187 kA SCCR at 240 V mean this breaker can sit at the service entrance or as a main disconnect on a large switchboard, where fault currents are highest. The 121 kA at 415 V and 53 kA at 690 V are the figures you'll reference for a 400 V or 690 V industrial feeder — the 415 V number covers the common 400 V class with margin. The ETU860 release supports ground-fault monitoring via summation current formation on the line conductor, and the unit includes communication functionality for integration into a higher-level monitoring system. The 3VA2580-5KQ32-0KA0 measures 210 mm wide, 320 mm high, and 120 mm deep. The 800 A frame size typically requires bolted connections rather than plug-in mounting, so plan for busbar or cable lugs rated for the full continuous current. ## Coordination and Selectivity Notes With the ETU860 release, you get adjustable long-time and short-time delay curves, which are the primary tools for achieving selective coordination with downstream breakers. The tr range of 0.5 to 25 seconds and tsd range of 0.05 to 0.5 seconds give you enough bandwidth to ride through transformer inrush and motor starting while still clearing a hard fault fast.","metaTitle":"Siemens 3VA2580-5KQ32-0KA0 SENTRON MCCB, 800 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2580-5KQ32-0KA0 molded case circuit breaker, 800 A rated continuous current, 3-pole, ETU860 release, 187 kA breaking capacity at 240 V.
