FAQs
This unit uses front terminals with bolt connections and a standard 6 N·m tightening torque, compatible with busbars sized 45.5 to 80 mm². Use a Main Circuit M6 screwdriver for secure terminations and verify approvals UL489/CSA. The 4P fixed configuration fits most standard MCC panels and skid-based power distribution layouts.
Important performance specs include In = 50 A with Ii = 500 A, UR = 600Y/347 V AC and 500 V DC, and Iu = 125 A. The device features 4 poles and TMF release with an opening time around 30 ms, and UL489 interrupting ratings up to 100 kA at 240 V AC, ensuring robust fault handling in industrial systems.
Yes. With XT1 sub-type, 4P fixed front terminals, and TMF/TM release, the breaker is designed for transformer and power distribution protection, offering reliable short-circuit interruption and selective tripping in transformer feeders and MCCs.
The XT1H 125 carries UL489 and CSA certifications, CE Declaration of Conformity, RoHS and REACH declarations, and CMRT. EPD availability and recyclability statements are provided, supporting sustainability reporting and responsible end-of-life handling.
Expect low maintenance given its solid-state TMF release and front-terminal design, minimizing field servicing time. With a rated life of thousands of switching cycles and a modular 4P frame, you gain uptime and predictable total cost of ownership, especially in high-availability production lines and critical power distribution.
