Eaton Specification Sheet - 125 TB
The 200 A amperage rating coupled with 5 jaws provides reliable current handling and secure conductor termination, improving system uptime and reducing thermal stress in high-load panels. This feature translates to lower risk of nuisance trips and longer service life for critical feeders in commercial facilities. The surface-mount mounting method simplifies retrofit projects and new installations alike, saving time on wall preparation and reducing installation labor costs. The 1Ø/3W configuration with a test block delivers straightforward wiring and quick verification during commissioning, minimizing startup delays. The ring cover and 3R enclosure offer durable exterior protection, enabling both overhead and underground feed configurations without compromising safety. Galvanized steel construction with ANSI 61 gray paint enhances corrosion resistance, lowering maintenance and replacement intervals. Lugs sized #6-250 MCM ensure broad compatibility with feeder cables, while the built-in test block supports on-site testing and troubleshooting, improving overall reliability and compliance. compatibility with Eaton’s B-Line series further simplifies integration into existing electrical architectures, reducing procurement complexity and inventory needs.
