Three-pole XT1 TMF release provides precise, predictable tripping, minimizing collateral outages and protecting downstream equipment in manufacturing lines. The TMF release, wired to the breaker, maintains a stable magnetic coordination against electrical disturbances. This translates into less unplanned downtime and faster fault isolation in complex power distribution schemes. The XT1 design supports modular installation in standard enclosures, simplifying future upgrades by preserving a common mounting footprint. Front-terminal design with bolt connections improves wiring reliability and speeds up panel assembly in crowded electrical cabinets. The front connection type and 6 N m tightening torque help ensure robust terminations in vibration prone environments, reducing terminal loosening risk. Rated current of 90 A and rated voltage of 600Y/347 V AC let this breaker protect typical industrial feeders and motor circuits. The high instantaneous short circuit setting Ii of 900 A and the rated uninterrupted current Iu of 125 A ensure stable operation under normal loads while providing rapid fault clearance in the event of a surge. The opening time of about 30 ms makes the protection action fast enough to limit damage. Low power loss per pole of 5.7 W reduces heat generation in compact switchgear and lowers energy cost for cooling. Compliance with UL489, CSA, CE, RoHS and REACH simplifies compliance workflows and procurement across global sites. Compatibility with SACE Tmax XT family and front-terminal busbar connections supports flexible installation across existing panels, with documented disassembly instructions and packaging for end of life recycling.
