The four‑pole XT1 design with plug‑in terminals enables rapid installation and seamless protection across all phases, reducing commissioning time and wiring errors in control panels. This translates to faster deployment and lower project risk in automotive, process, and material handling environments. The 40 A rating supports reliable machine protection without overprotecting circuits, improving selectivity and reducing nuisance trips in automated lines. Operating at 690 VAC and 500 V DC with Uimp of 8 kV ensures safe interruption of faults across mixed power systems, enabling cleaner handoffs between power conversion stages and drives. Electrical durability of 8000 cycles and mechanical durability of 25000 cycles extend service life, lowering maintenance costs and downtime during upgrades or refurbishments. Power loss of 4.6 W per pole minimizes heat generation in panels, contributing to cooler enclosures and better overall efficiency. Regulatory compliance is maintained through RoHS, REACH, CMRT, and WEEE disclosures, simplifying global procurement and sustainability reporting. The SACE Tmax XT family compatibility ensures easy replacement and standardized protection across existing installations, supporting scalable upgrades without re‑engineering.
