Front-terminal design with bolt connections simplifies wiring during panel assembly, reducing field labor and risk of misconnection. This improves installation speed and reliability in demanding industrial environments, especially where 32.5–100 mm² busbar conductors are used in 3P layouts. TMF release delivers reliable protection with a 30 ms opening time when SOR or UVR conditions occur. In practice, this minimizes arcing duration and protects downstream equipment across manufacturing lines and critical power feeds. Rated current is 20 A with a rated instantaneous short-circuit setting of 400 A, enabling compact protection for light-to-medium loads. The 600 V AC / 500 V DC rating supports mixed-voltage systems in industrial plants. Electrical durability of 8000 cycles and mechanical durability up to 25,000 cycles indicate long service life under frequent switching and load transients, reducing maintenance downtime. ABB’s Tmax XT includes an EPD and a design-for-closing resource loop with a recyclability rate of about 55.7 percent per EN45555. Disassembly instructions support end-of-life reuse and responsible disposal in regulated facilities. The product aligns with SACE Tmax XT family, with front-terminal accessibility and a recommended screw driver (M6) supporting streamlined installation in service panels and cabinets.
