FAQs
The XT2H 125 TMF uses fixed front terminals designed for straightforward panel mounting. It supports busbar connections from 32.5 to 100 mm2 and requires a tightening torque of 6 N·m with a Main Circuit M6 screwdriver. Its 3P configuration fits typical small to medium distribution panels, simplifying wiring and reducing assembly time during retrofit projects.
Key specs include rated current of 25 A, rated operational voltage of 600 V, and a rated instantaneous short-circuit current setting of 400 A. The interruption rating varies by voltage: up to 150 kA at 240 V AC, 65 kA at 480 V AC, and 25 kA at 600 V AC, with DC ratings also provided. The device uses a TMF release for fast opening and offers reliable AC/DC operation.
Yes. With 3P configuration, a 125 A TMF release, and a 25 A rated current, the XT2H is well-suited for motor protection in panels and MCCs. The fast opening time and considerable short-circuit protection help safeguard motor feeders, while front terminals support quick integration into existing layouts and easy maintenance access.
This unit carries UL489/CSA compliance, a CE declaration of conformity, and RoHS/REACH compliance. It also provides a CSA certificate, UL listing, and environmental declarations including EPD and recyclability metrics. These certifications support regulatory alignment in North America and Europe and facilitate supplier qualification audits.
Electrical durability is rated at 8000 cycles and mechanical durability at up to 25000 cycles, with a rated voltage of 600 V and Iu of 125 A. These figures indicate long service life with predictable performance, reducing replacement frequency. The front-terminal design and standardized tightening torque streamline servicing, cutting downtime and improving total cost of ownership in continuous operation environments.
