The 3VA1112-6GF42-0AA0: Compared to the 3VA1112-5EE32-0AA0 (also a 4-pole 125 A MCCB but with a different trip curve and lower interrupting ratings), this 6GF42 variant carries the higher SCCR — critical if your panel's available fault current exceeds 100 kA at 240 V. The physical footprint is identical: 101.6 mm wide, 130 mm tall, 70 mm deep. 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.
Mounts on a standard DIN rail or can be screw-mounted to a backplate. The front face carries an IP40 protection class — fine for a clean indoor panel, but not for washdown areas. 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.
