Feature → Business Impact → Application: The 3P XT2 S1164 style design (XT2S160 DC TMA50 FF 3P) provides reliable DC protection with a compact footprint, reducing panel space without compromising safety. This translates to lower enclosure costs and easier installation in space-constrained switchgear and distribution panels used in automation and battery systems. Application includes DC power distribution in motor drives and renewable energy installations, where reliability is critical. Feature → Business Impact → Application: Ics/Icu ratings up to 50 kA at 250/500 V DC enable robust fault handling for high-energy DC circuits, reducing unplanned downtime and equipment damage. Use this in high surge environments such as DC bus barriers and battery charging stations to maintain uptime and protect downstream drives and loads. Feature → Business Impact → Application: Fixed terminal connection and 3-pole design simplify wiring and commissioning, cutting install time and wiring errors. This is advantageous for OEM assembly lines and retrofit projects where fast, repeatable installation is essential. Feature → Business Impact → Application: Mechanical durability rated at 25,000 cycles and 240 cycles per hour provides long service life under frequent switching, lowering maintenance intervals and total cost of ownership in conveyor, press, and automation cells. Feature → Business Impact → Application: Power loss of 4.09 W per pole minimizes heat generation, contributing to tighter thermal management in compact enclosures and reducing cooling requirements in data- and control-panel environments. Feature → Business Impact → Application: ABB EcoSolutions and End Of Life Disassembling Instructions support sustainable design and responsible disposal, helping facilities meet corporate sustainability targets and regulatory obligations. Feature → Business Impact → Application: RoHS and REACH declarations, along with a 55.7% recyclability rate per EN45555, align with global environmental compliance and reduce lifecycle risk for customers pursuing green procurement.
