For DC systems the manual specifies separate values — the listing notes that the 3VA Molded Case Circuit Breaker Manual covers those curves. The overcurrent release is a TM220 thermal-magnetic type — fixed thermal pickup, magnetic trip adjustable. If you need those functions they go external or you step up to a different release variant. That's a standard SENTRON 3VM footprint — it occupies the same panel cutout as other 4-pole frames in the family, so a swap from a 3VA1112-5EE32-0AA0 should drop in without re-drilling the mounting plate. Check the lug kit compatibility if you're reusing busbars; the termination pattern is the same across the 3VM platform but lug tunnel sizes differ with the frame rating.","metaTitle":"SENTRON 3VM1225-4GE42-0AA0 Molded Case Circuit Breaker, 250","metaDescription":"SENTRON 3VM1225-4GE42-0AA0 4-pole MCCB, 250 A rated at 40-50 °C, breaking capacity 121 kA at 240 V.
