Eaton 1M1RP Meter Breaker - UL Listed, 100A, 120/240V
Part Number: 1M1RP
Quick Summary
Eaton B-Line meter breakers protect single-meter installations by delivering compact, reliable overcurrent protection for electrical panels. Facilities often wrestle with limited space, wiring complexity, and meeting demanding 10 kAIC interrupt requirements. UL Listed and EUSERC Approved certifications support utility acceptance and code compliance, while the galvanized steel enclosure and ANSI 61 gray finish endure harsh environments. With a robust 100 A main and a single-meter arrangement, this solution enables easier installation and scalable protection while controlling operating costs. This combination of performance and durability translates to lower maintenance, faster deployment, and predictable budgeting for facilities and data-center environments.

FAQs
The 1M1RP is designed for single-meter position applications within Eaton B-Line meter socket systems. It supports surface mounting and overhead mounting configurations with an AW hub, aligning to standard meter socket footprints. Its 4.625 in depth, 8 in width, and 24 in height provide a compact footprint suitable for utility rooms and service enclosures, while aluminum bus conductors ensure reliable electrical connections.
The unit provides a 100 A amperage rating at 120/240 V, single-phase, with a 10 kAIC interrupt rating and a main circuit breaker of (1) 100 A, 3P. This combination supports robust overcurrent protection for single-meter services, aligning with typical service entrance requirements and allowing safe, code-compliant operation in distribution panels.
Yes. The 1M1RP is UL Listed and EUSERC Approved, signifying adherence to recognized safety standards and utility specifications. This dual certification facilitates utility approvals, inspections, and code compliance across multiple jurisdictions, reducing project risk and accelerating procurement and commissioning.
Yes. The 1M1RP is designed for single-meter positions and is compatible with Eaton B-Line meter socket systems. Its mounting options, enclosure construction, and bus design support both overhead and surface installations, enabling flexible integration into existing or new utility enclosures and service panels.
With UL and EUSERC certifications and a galvanized steel enclosure, maintenance is typically infrequent. The durable ANSI 61 gray finish resists corrosion, while the 16 lb weight and compact 4.625 in depth simplify handling and replacements. The predictable performance of a 100 A, 120/240 V, 10 kAIC unit translates to lower downtime and faster deployment, improving total cost of ownership.
