Feature → Business Impact → Application: The 4P XT1H design with front terminals enables faster wiring and cleaner panel layouts, improving installation efficiency and reducing field labor costs in distribution panels for transformers and motor control centers. This translates to measurable time savings during commissioning and easier future maintenance in brownfield sites. The rated current of 15 A with a rated operational voltage of 600Y/347 V AC (and 500 V DC) supports compact, energy-efficient power distribution for small machinery and control circuits, delivering predictable protection without oversizing components. The TMF release mechanism provides reliable thermal-magnetic protection with a setting range around 15 A, improving selectivity and reducing nuisance trips in busy industrial environments. The 4P configuration, front terminals, and bolt-type connections paired with a 6 N·m tightening torque enable solid, vibration-resistant connections in panel boards and switchgear. With a busbar compatibility range of 45.5 to 80 mm², installers can reuse existing busbars and standardize across multiple panels. The device’s robust UL489 interrupting ratings (up to 100 kA at 240 V, 65 kA at 480 V, 25 kA at 600Y/347 V) ensure protection for both feeders and transformer feeds under fault conditions. Its compact dimensions (101.6 mm W × 130 mm H × 70 mm D) and weight (1.4 kg) facilitate easy rack mounting and scalable protection in modular assemblies. The unit’s low power loss (about 1.1 W per pole) supports energy-efficient protection schemes in continuously energized systems. ABB’s environmental declarations, including EPD, RoHS, REACH, and CMRT, support sustainability reporting and regulatory compliance for modern projects. In scenarios demanding high reliability and compliance, the XT1H 125 TMF delivers a proven solution that minimizes downtime and simplifies lifecycle management.

FAQs
Install the XT1H 125 TMF in a compatible panel using the front-terminal connections. Use a M6 screwdriver for main circuit terminals, tighten to 6 N·m, and ensure the busbar section is within 45.5 to 80 mm². Verify the device is oriented for accessible wiring and that assembly conforms to UL489 and local electrical codes.
For 600Y/347 V AC, the interrupting rating is up to 25 kA, with higher ratings available at other voltages (240 V AC up to 100 kA; 480 V AC up to 65 kA). These values ensure adequate fault protection for feeders and transformer feeds in industrial installations.
Yes. The device is part of the SACE Tmax XT family designed for low‑voltage transformer and distribution protection with four poles, front terminals, and TMF release, delivering reliable overcurrent protection for transformer feeders and associated switchgear in industrial environments.
The MCCB carries UL489 and CSA certifications, plus a CE Declaration of Conformity. It also aligns with RoHS and REACH declarations, CMRT for conflict minerals, and other ABB EcoSolutions commitments for lifecycle and sustainability reporting.
TMF (Thermal-Magnetic) release provides precise overcurrent protection with defined trip curves, improving selectivity and reducing nuisance trips. The unit supports robust operating and mechanical durability metrics, enabling predictable performance across frequent switching cycles in demanding industrial applications.
