It carries an ETU860 electronic trip unit — fully adjustable for long-time (tr 0.5–25 s), short-time (tsd 0.05–0.5 s), and instantaneous protection, with Ir adjustable up to 1000 A. Rated for line protection (not motor-only), this MCCB delivers full-genealogy traceability through the SENTRON platform — the ETU860 logs event data and supports communication functions, enabling integration with higher-level monitoring systems for predictive maintenance and fault analysis. At 60 °C ambient the breaker carries 955 A; at 70 °C it derates to 815 A. Maximum power loss is 123 W. Panel builders should account for this heat dissipation when calculating enclosure ventilation and busbar ampacity — the 120 mm depth and 210 mm width fit standard MCCB mounting footprints, but adjacent devices must be spaced per Siemens derating guidelines to avoid nuisance tripping.","metaTitle":"Siemens 3VA2510-5KQ32-0JA0 SENTRON MCCB, 1000 A, 3-pole, ETU","metaDescription":"Siemens SENTRON 3VA2510-5KQ32-0JA0 molded case circuit breaker, 1000 A, 3-pole, ETU860 trip unit, 187 kA at 240 V.
