Eaton BKD2F125B Pow-R-Xpress main breaker kit - UL 67

125 A protection is built into the BKD2F125B, enabling reliable overcurrent protection for branch circuits in distribution panels. The Pow-R-Xpress design translates to faster coordination with feeders and downstream devices, reducing mis-timing during startup and shutdown. In practice, engineers deploy this kit in commercial and light industrial panelboards where space is limited but protection must be immediate. With dimensions of 6 in length, 4 in width, and 3 in height, and a weight of 5 lb, the kit fits tight enclosures and retrofit spaces without sacrificing strength. The compact BOT MCB KIT integrates into existing Eaton panelboards with minimal modification, enabling quicker changes during capacity upgrades or safety improvements. This translates to measurable installation time savings and lower field labor costs. UL 67 certification paired with NEMA compliance provides regulatory confidence for new builds and retrofit projects alike. These standards help you meet local electrical codes while maintaining consistent performance under normal and fault conditions. The kit's certification footprint also supports confident procurement and simplifies audit trails for maintenance programs. Designed to work within the Pow-R-Xpress ecosystem, BKD2F125B offers plug-and-play compatibility with panelboards and feeders that use BOT MCB kits. The robust build supports repeated load cycling typical in commercial lighting and HVAC controls, with a lifecycle aligned to Eaton's reliability metrics. Access to Eaton's quick selector references, procedure guides, and specification sheets accelerates project design and commissioning. Available downloads include brochure references and a specification sheet, which reduces mis-selection and supports engineering teams during procurement and commissioning.
