Three-pole XT1 design with fixed front terminals optimizes wiring and fault isolation, reducing panel depth and installation time. This configuration supports clean, ladder-friendly wiring and straightforward field servicing, delivering tangible efficiency gains in MCCs. Rated current In is 50 A with a rated uninterrupted current Iu of 125 A, enabling reliable continuous operation for moderate motor loads, while the adjustable instantaneous short-circuit current setting Ii from 150 to 550 A allows precise coordination with downstream protections and minimizes damage from faults. Operating voltage ratings of 600Y/347 V AC and 500 V DC cover typical industrial power distribution and DC bus scenarios, supporting diverse applications in process and manufacturing environments. The device’s UL489 and CSA listings, along with CE DoC, RoHS, and REACH declarations, simplify compliance and speed up approvals, while ABB EcoSolutions and end-of-life documentation support sustainability goals. A tightening torque of 6 N·m and front-terminal bolt connections streamline installation, and packaging at 1 piece per box aids inventory control. Designed for compatibility with Tmax XT ecosystems, it integrates with ABB wiring diagrams and maintenance procedures for quicker training and faster replacement in critical processes.

FAQs
For XT1 3P fixed front-terminal models, use the recommended M6 screwdriver and tighten to 6 N·m. The front-terminal design simplifies wiring in tight panels, supports busbar connections sized 45.5 to 80 mm², and enables straightforward field maintenance without rear access. Ensure compatible enclosure spacing and clearances per NEC/IEC guidelines to maintain safe operation.
This breaker has a rated current In of 50 A, a rated uninterrupted current Iu of 125 A, and an adjustable instantaneous short-circuit current setting Ii from 150 to 550 A. It operates at 600Y/347 V AC and 500 V DC, with a short-circuit rating per UL489 up to 100 kA at 240 V, 65 kA at 480 V, and 25 kA at 600Y/347 V. Standards include UL489.
Yes. The ABB Tmax XT1 is designed for motor protection within MCCs and control panels.
