Eaton 225 MTB Meter Breakers - UL Listed 200 A
Part Number: 225 MTB
Quick Summary
Eaton 225 MTB meter breakers provide reliable meter socket protection for commercial and industrial electrical feeders. Engineers and procurement teams often struggle with installation time, wiring complexity, and cross-compatibility across meter sockets. They are UL listed and EUSERC approved, with ANSI 61 gray finish over a mill-galvanized steel body to ensure durable, corrosion-resistant performance in demanding environments. This model's surface-mount design, 200 A rating, and 1Ø/3W configuration translate to faster project delivery, predictable performance, and reduced lifecycle costs for utility metering and multi-tenant installations. Its 6 in depth, 14 in width, and 48 in height provide a compact, space-efficient footprint that simplifies retrofits and new builds.

200 A amperage rating provides robust protection for demanding feeders, reducing nuisance tripping while enabling larger service profiles. This rating translates to fewer breakers in parallel and more straightforward load calculations during design reviews for industrial facilities. The 10 kAIC interrupt rating enhances fault tolerance, limiting equipment damage and downtime in fault conditions and helping meet facility reliability targets. Five jaws, a single 1 Position configuration, and an integrated test block streamline commissioning, wiring, and future maintenance, cutting field labor and reducing inspection risk. Wide conductor compatibility with #6-250 MCM supports flexible feeder design and simplifies ordering for complex metering installations. The galvanized steel body with ANSI 61 gray finish delivers corrosion resistance in harsh environments, while UL listing and EUSERC approval provide regulatory assurance for utility metering projects. The surface-mount 3R enclosure and ring/ringless compatibility reduce installation time and improve field fit in limited spaces, making this meter breaker an economical choice for both new builds and retrofit programs.

FAQs
The 225 MTB is designed for surface-mount meter sockets with 1Ø/3W configuration and supports ring or ringless metering. Plan for a 6 in depth, 14 in width, and 48 in height enclosure to fit standard B-Line metering layouts. Ensure conductor sizes fall within the #6-250 MCM range and that the test block is accessible for commissioning and periodic testing. Its 5 jaws and single position simplify the wiring process, reducing install time and rework.
Yes. The 225 MTB is rated for 200 A with a 10 kAIC interrupt rating, ensuring reliable interruption of fault currents and protection for feeders and downstream equipment. This combination is suitable for commercial and industrial metering installations where higher fault tolerance is required, helping to meet system reliability targets and utility requirements.
The 225 MTB carries UL certification and is EUSERC Approved, supporting utility and end-user compliance requirements. The combination of UL listing and EUSERC approval provides confidence in safety, performance, and compatibility with standard metering practices used in commercial and multifamily projects.
Yes. The 225 MTB supports 1Ø/3W metering and is specified for ring and ringless metering configurations, offering flexibility in meter socket design and installation. This versatility helps accommodate various utility and building owner preferences while maintaining consistent protection and performance across installations.
The 225 MTB enhances ROI through faster commissioning thanks to its 5-jaw, 1-position design and test block, reducing field labor. Its corrosion-resistant galvanized steel housing and ANSI 61 gray finish minimize maintenance costs in harsh environments. UL and EUSERC compliance reduce regulatory risk, while the 200 A rating and 10 kAIC interrupt rating improve reliability, reducing downtime and extending service life for metering installations.
