It drops into the same panel cutout and bus connection without rewiring, so a BOM substitution is straightforward as long as the trip curve matches the load. Lifecycle status is current — no phase-out or NRND flags. That means the supply chain is stable; no last-time-buy clock ticking. For compliance, the SENTRON series carries UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications. RoHS and REACH declarations are standard from Siemens. If you need a formal declaration for your compliance file, it's available on request. The 4-pole design includes 100% rated neutral protection, so it's suited for three-phase plus neutral systems. The TM240 release is thermal-magnetic, adjustable for thermal pickup via a dial on the front. No undervoltage release or shunt trip fitted as standard — those are add-on accessories.","metaTitle":"Siemens SENTRON 3VA1112-6GF42-0AA0 MCCB, 125 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1112-6GF42-0AA0 molded case circuit breaker, 125 A, 4-pole, TM240 release, 220 kA at 240 V.
