Feature → Business Impact → Application: The DC rated current of 400 A and 750 V DC operating voltage deliver robust protection for 3P DC networks, reducing the risk of arc faults and unintended trips in harsh industrial environments. This translates to improved line availability and safer control panels in automotive, steel, and process industries. Application: DC power distribution, motor control centers, and automation cabinets where reliable protection is critical. Feature → Business Impact → Application: The XT5 TM release with a 20,000-cycle mechanical durability provides long-term reliability and predictable maintenance intervals, lowering lifecycle costs and downtime in continuous-process facilities. Application: Heavy machinery protection and high-cycle control systems requiring durable switching. Feature → Business Impact → Application: Fixed terminal connections and compact footprint (140 mm x 205 mm x 103 mm, 3.25 kg) simplify installation and retrofit projects, speeding up panel builds and reducing field wiring errors. Application: Retrofit of legacy systems and space-constrained panels. Feature → Business Impact → Application: Environmental and compliance data (EPD, RoHS/REACH, 59.6% recyclability per EN45555) support green procurement and end-of-life planning, helping OEMs meet sustainability targets. Application: Green IT/industrial automation programs and audited supply chains.
