Three-pole XT1N with front-terminal connections and TMF release translates into faster wiring and safer operation. This design minimizes panel contamination and reduces assembly time, while the front-term arrangement simplifies inspection and testing during commissioning. Application: motor control centers and switchgear assemblies in harsh industrial environments benefit from easier installation and quicker fault isolation. The unit supports mixed networks with a rated voltage of 600Y/347 V AC and 500 V DC, enabling seamless integration into systems that use both AC and DC feeds, reducing inventory complexity and simplifying upgrades. With a 25 A nominal current and a 500 A instantaneous setting, it delivers selective protection for feeders and motors, limiting unnecessary trips and improving process uptime. Front terminals and bolted connections at 6 N·m tightening torque enable reliable field installation with repeatable contact pressure. Busbar compatibility of 45.5–80 mm² reduces wiring footprint while maintaining solid electrical performance. Electrical durability of up to 8000 cycles and mechanical durability up to 25000 cycles ensure long service life in demanding environments. Compliance features include UL489, CSA, RoHS, REACH, CMRT, and EPD declarations, supplemented by end-of-life disassembly instructions for responsible recycling. ABB EcoSolutions integration supports packaging disposal guidance and site-level waste reduction programs, contributing to lower total cost of ownership over the product lifecycle.

FAQs
Install as a 3P front-terminal device with bolted terminals and 6 N·m tightening torque. Use busbar range 45.5–80 mm² and ensure secure mounting in a compatible panel. The front-terminal design simplifies wiring, inspection, and commissioning, while the TMF release requires standard maintenance access for testing of the thermomagnetic trip. Verify terminal polarity and verify conformity to UL489 and CSA CS22.2 standards during commissioning.
The 25 A rated current (In) defines normal operating current, while the 500 A rated instantaneous short-circuit setting (Ii) provides rapid tripping under fault conditions. This combination supports selective coordination with upstream devices, minimizing downtime and protecting feeders and motors without nuisance tripping under normal starting surges. Design your protection scheme to match circuit loads and fault current levels in the installation.
Yes, the XT1N is specified for AC and DC operation. Rated operational voltage is 600Y/347 V AC and 500 V DC, enabling use in mixed networks common in industrial automation. This versatility supports motor control centers and panel boards where both supply types are present, reducing the number of different devices required on site.
The device carries UL489 and CSA certifications, plus a CE Declaration of Conformity. Additional environmental declarations include RoHS, REACH, CMRT, and an Environmental Product Declaration (EPD) for Tmax XT. End-of-life disassembly guidance is provided to assist in recycling, contributing to regulatory adherence and sustainability programs across regions.
ROI benefits come from reduced downtime due to fast fault isolation (30 ms opening) and reliable front-terminal installation that speeds commissioning. Mechanical and electrical durability (up to 25000 and 8000 cycles respectively) lowers replacement frequency. Lifecycle support includes disassembly instructions and EPD/ RoHS compliance, which simplify maintenance planning, spare part management, and end-of-life recycling investments.
