Eaton U227 MTBH Meter Breakers - 200A, 42kAIC UL
Part Number: U227 MTBH
Quick Summary
Eaton U227 MTBH meter breakers are heavy-duty protection devices for metering panels in commercial and industrial installations. A common challenge is delivering reliable, code-compliant metering that can safely interrupt 200 A loads while minimizing panel space and installation time. UL listing and EUSERC approval accompany a 42 kAIC interrupt rating, delivering robust short-circuit protection aligned with utility and NEC requirements. Designed for surface-mount installation in 3Ø/4W configurations, it supports up to #6-250 MCM conductors and is built in a steel enclosure with ANSI 61 gray finish. Together with its test block, 7 jaws, ring geometry, and 1-position mounting, this unit helps contractors meet schedule demands while maintaining long-term reliability.

FAQs
The U227 MTBH is designed for #6-250 MCM conductors and comes in a steel enclosure with a 3Ø/4W configuration suitable for surface-mount installations. It features a 6 in depth, 22 in width, and 30 in height footprint with a test block, 7 jaws, ring connections, and a 1-position mounting scheme, enabling straightforward retrofits in B-Line meter mounting systems and other compatible enclosures.
Key specs include a 200 A amperage rating and a 42 kAIC interrupt rating, suitable for high fault currents. The device supports 3Ø/4W configurations and is designed for surface mounting. It accepts #6-250 MCM conductors and is built with a steel enclosure finished in ANSI 61 gray paint, providing robust protection and durability.
Yes. The U227 MTBH meter breaker is UL listed, which confirms compliance with safety standards, and it carries EUSERC approval, ensuring compatibility with utility requirements and metering installations. These certifications support easier procurement, utility acceptance, and NEC-aligned protection in commercial and industrial projects.
Plan for surface-mount installation in 3Ø/4W metering panels with a footprint of 6 in depth by 22 in width and 30 in height. Be prepared for a heavier unit (approximately 73 lb) requiring careful handling. Ensure conductor termination within #6-250 MCM, and leverage the 1-position mounting with 7 jaws and a test block for secure, verifiable connections.
ROI comes from improved reliability and faster fault isolation due to the 42 kAIC interrupt rating, UL/EUSERC compliance reducing regulatory risk, and longer service life from a steel enclosure with durable ANSI 61 gray finish. The combination of robust protection, wiring versatility, and straightforward installation translates to lower downtime, fewer panel changes, and predictable maintenance costs over time.
