That means in a hot panel — say near a furnace line or in a non-climate-controlled enclosure — you still get full current without tripping prematurely. The 70 mm depth, 140 mm width, and 158 mm height fit standard SENTRON mounting patterns — it swaps into existing 3VA panel cutouts without re-drilling gland plates. ## Derating and thermal management That heat has to exit the enclosure — in a sealed panel, factor that into the thermal budget. Four auxiliary switches (HQ type) are built into the supplied basic switch 3VA12256GF420AA0. That gives you two NO + two NC contacts for remote trip indication or status feedback without adding an external aux block. Siemens lists this part as current-production — no phase-out notice, no last-time-buy window. The SENTRON 3VA series is the active platform replacing the older 3VL line. For BOM continuity, this code is the one to freeze into new designs.","metaTitle":"3VA1225-6GF42-0AE0 SENTRON MCCB, 250 A, 4-Pole, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1225-6GF42-0AE0 molded case circuit breaker, 250 A, 4-pole, TM240 release, 220 kA at 240 V.
