Interrupting capacity is where this breaker earns its keep in high-fault installations: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That's a lot of headroom for most commercial and industrial service entrances — you're not going to run out of SCCR on a typical 480 V panel feed. Physical footprint is 70 mm deep by 140 mm wide by 158 mm tall — a standard 4-pole MCCB form factor that drops into SENTRON mounting bases without surprises. ## Lifecycle and sourcing — still current, no obsolescence worry This part carries a current lifecycle stage from Siemens — no phase-out, no last-time-buy notice. It's an active catalog item in the SENTRON 3VA family, so you're not hunting surplus or chasing a replacement. ## Integration notes — what fits and what doesn't The breaker ships with three auxiliary switches (HQ design) integrated, so you get status feedback without adding external contact blocks. If you need those options, you're looking at a different variant in the 3VA family. The 70 mm depth means it fits standard SENTRON mounting plates and busbar systems without clearance issues.","metaTitle":"Siemens 3VA1225-6GF42-0AD0 SENTRON MCCB, 250 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1225-6GF42-0AD0 molded case circuit breaker, 250 A fixed rating, 4-pole, TM240 thermal-magnetic release.
