Eaton MB48B200BTS Meter Breaker - 10 kAIC
Part Number: MB48B200BTS
Quick Summary
MB48B200BTS is a residential meter breaker providing integrated metering and protection for 120/240 V single‑phase service. Contractors and engineers often contend with bulky assemblies, mismatched components, and extended commissioning times when meters, lugs, and protection devices are sourced separately. This unit carries UL Listed certification and a NEMA 3R outdoor enclosure, plus a 10‑year warranty and a 10 kAIC interrupt rating for robust fault management. By consolidating functions into one enclosure, it streamlines installation, reduces wiring complexity, and supports faster utility approvals. In power distribution for homes and light commercial sites, it delivers reliability, simpler maintenance, and a lower total cost of ownership.

Eaton Specification Sheet - MB48B200BTS
All-in-one design reduces installation steps and space by integrating meter, feed-through lugs, and main protection into a single enclosure, cutting labor time and minimizing field connections for faster commissioning. The 10 kAIC interrupt rating enhances fault tolerance, supporting safer service restoration during short-circuits while meeting utility requirements for residential service entrances. A rugged NEMA 3R outdoor enclosure combined with surface mounting and top/bottom feed delivers reliable operation in exposed environments, reducing weather-related maintenance and ensuring code compliance in diverse installation sites. Aluminum bus and four-jaw lugs provide robust, corrosion-resistant connections suitable for #6-350 kcmil grounds, improving long-term reliability and reducing rework due to poor grounding. Compatibility with BR breakers simplifies stocking, while UL Listed certification and a 10-year warranty offer strong total-cost-of-ownership advantages for utilities and contractors alike. The compact box size A optimizes space in tight meter locations without sacrificing accessibility for service upgrades and routine inspections.
