ABB 2TFH102112R1001 Moulded Case Circuit Breaker - 60947-2

The 2TFH102112R1001 is a four-pole, 125 A Moulded Case Circuit Breaker that operates up to 690 V AC and 500 V DC, enabling broad compatibility across mixed voltage installations in automation and machinery. This feature translates to improved system uptime, reduced nuisance tripping, and fewer field adjustments during commissioning. In practice, installers appreciate the withdrawable mounting design that simplifies insertion, testing, and maintenance in dense control panels, lowering labor costs and downtime. The device delivers a robust 8 kV impulse withstand and 100 kA short-circuit breaking capacity (Ics) with up to 100 kA ultimate capacity (Icu) across selected voltages, supporting safe fault isolation in high-energy environments while meeting IEC 60947-2 requirements. RoHS and REACH declarations further ensure regulatory alignment, decreasing supply-chain risk and enabling global deployment. The Tmax XT family integration provides familiar characteristics, including TMA/TM release with a 4P protection scheme that reduces arc exposure during operation and maintenance, while the 125 A rating supports medium-load applications in packaging, materials handling, and process automation. Industry-specific durability—8000 electrical cycles and 25000 mechanical cycles—means fewer replacements in continuous-operation lines, translating to lower total cost of ownership and predictable maintenance planning. Compatibility with withdrawable breakers facilitates modular expansion and quick swap-outs during optimization projects, helping engineers adapt to evolving plant layouts without rewiring entire sections of the panel.
