Feature → Business Impact → Application: The 3P configuration, rated 125 A, and DC operation target high-current DC distribution with stable trip characteristics, reducing nuisance trips and improving line reliability in control panels. This translates to fewer production interruptions and lower maintenance costs for conveyor and machine-line systems. The XT4 TM release (TMD/TM) provides rapid, predictable protection against short circuits, enabling safe startup sequences in automated equipment and data-center rack power distributions. With an insulation rating of 1000 V and 750 V DC nominal, it supports high-voltage DC bus protection in renewable energy inverters and motor drives, while the 8 kV impulse withstand enhances surge resilience in demanding factory environments. The device’s fixed terminal connections simplify installation and reduce commissioning time during panel assembly, improving overall project timelines. Energy loss is minimized at 7.40 W per pole, contributing to cooler, more efficient power distribution boards in compact control enclosures. The product is aligned with ABB EcoSolutions, End Of Life disassembly instructions, and a measurable recyclability rate (56.3% per EN45555), supporting sustainability-driven procurement. RoHS/REACH compliance and CMRT readiness offer compliance confidence for global customers, while the low weight of 2.5 kg eases handling during installation and retrofits in existing panels. Compatibility with XT4 DC IEC installation instructions ensures a familiar, streamlined mounting process for engineers upgrading legacy CBs.
