Front-terminal mounting with the TMF release enables quick wiring and safer maintenance. This reduces commissioning time and minimizes exposure to live parts, cutting on-site labor costs. Ideal for motor control centers and transformer feeder panels in industrial environments. Four-pole XT1 design with 600Y/347 V AC and 500 V DC ratings delivers coordinated protection for multi-phase loads. The result is improved system reliability and reduced fault propagation across feeders. Rated current of 45 A and a 45 A setting range allow precise coordination with downstream devices. This makes it easy to tailor protection to specific loads and ensures selectivity in factory distribution boards. ABB EcoSolutions support; EPD for Tmax XT; 55.9% recyclability per EN45555 and compliance with RoHS and CMRT documentation. Electrical durability up to 8,000 cycles per hour and mechanical durability around 25,000 cycles ensure long service life in busy plants. Front-terminal bolts with a tightening torque of 6 N·m and a recommended M6 main circuit screwdriver simplify installation and future servicing. Standar ds compliance with UL489 and CE DoC ensures regulatory alignment and interchangeability across global sites.

FAQs
The unit uses front-terminal connections and is compatible with busbar sizes from 45.5 to 80 mm². It uses a 6 N·m tightening torque with M6 main circuit screws, and the compact XT1 footprint fits standard 4P panel layouts.
It is a 4P device with a rated current of 45 A, rated operational voltage of 600Y/347 V AC and 500 V DC, rated uninterrupted current of 125 A, and a setting range of 45 A. It supports AC/DC operation and provides 500 A short-circuit instantaneous settings.
The device complies with UL489 and UL/CSA requirements, carries CE conformity, and is documented with RoHS, CMRT, TSCA, and EN45555 environmental and sustainability data, including an EPD for Tmax XT.
Ideal for motor control centers, transformer feeders, and distribution panels requiring reliable six‑point protection, front-terminal wiring, and easy maintenance in harsh industrial environments.
Durability is rated at up to ~8,000 electrical cycles and ~25,000 mechanical cycles, reducing replacement frequency. Front-terminal design shortens servicing time, and ENVIRONMENTAL declarations (EPD, EN45555) support sustainability reporting and potential lifecycle cost reductions.
