It carries a breaking capacity of 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that place it squarely in high-fault-current distribution panels, typically downstream of a transformer or in a main feeder position where available fault current is substantial. The 140 mm width and 181 mm height fit standard SENTRON 3VA switchboard mounting; the 86 mm depth leaves room for rear-access cabling in a typical enclosure. The power loss of 0.5 W maximum is negligible for thermal budgeting.","metaTitle":"Siemens SENTRON 3VA2025-8JQ42-0AA0 MCCB, 25 A, 4-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2025-8JQ42-0AA0 molded case circuit breaker, 25 A rated, 4-pole, ETU560 release, breaking capacity 440 kA at 240 V.
