FAQs
Yes. The U227 MTBP MS15 is designed for ring and ringless metering configurations commonly used in commercial and industrial installations. It supports 3Ø/4W service with 7 jaws and a test block, simplifying integration with existing metering sockets and reducing the need for adapter components in both retrofit and new-build projects.
Key specs include a 200 A amperage rating and a 200 kAIC interrupt rating, UL-listed certification, and EUSERC approval. These ratings ensure strong fault-current protection, regulatory compliance, and utility-grade acceptance, making it suitable for service entrances and main distribution in demanding environments.
Plan for a surface-mount installation in a suitable enclosure or mounting panel. The unit is constructed from galvanized steel with a 6 inch depth, and its 22 by 30 inch footprint and 64 lb weight require careful handling and enclosure space planning. It’s designed to fit Eaton B-Line meter mounting equipment for streamlined commissioning.
The U227 MTBP MS15 is UL-listed and EUSERC-approved. These certifications verify safety performance and utility compatibility, accelerating procurement, regulatory acceptance, and field inspections—critical for utility-backed projects, code compliance, and standardized panel assemblies.
The integrated design with 200 A capacity, robust 200 kAIC protection, and durable galvanized finish reduces parts count and maintenance needs. Its compatibility with metering configurations minimizes field engineering time, while UL and EUSERC certifications support faster procurement and longer service life, delivering lower lifecycle costs in commercial and industrial power distribution.
