Eaton residential meter breaker CMBE24B125TSR - UL Listed, EUSERC Approved
Part Number: CMBE24B125TSR
Quick Summary
Eaton residential meter breaker CMBE24B125TSR provides main overcurrent protection for retrofit metering in residential panels. Retrofitting meters often creates compatibility and space challenges, risking outages and costly downtime. This unit carries UL Listed and EUSERC Approved status, with a rugged NEMA 3R enclosure for outdoor or semi-exposed installations. Built for Type CH breaker compatibility and aluminum bus, it simplifies field wiring and reduces installation time. The 125A main rating, 22 kAIC interrupt and 4 circuits support efficient, code-compliant metering in new builds or upgrades, while the surface-mounted design and overhead feed facilitate flexible mounting in limited spaces. For procurement teams, the combination of robust protection and predictable performance translates to lower total cost of ownership.

125A main rating delivers strong protection for residential feeders, reducing the risk of nuisance trips and electrical fires in retrofit installations. This directly translates to improved reliability for critical loads and easier utility approvals in retrofit projects. The 22 kAIC (and 35 kAIC interrupt rating where applicable) specification supports higher fault current scenarios, offering s ource-to-load protection across varied panel configurations, while maintaining compatibility with Type CH break ers and CSR2125BM main configurations. Four circuits across two spaces with one socket simplify panel design and future expansion, enabling scalable metering without costly hardware changes. Aluminum bus and overhead feed reduce weight and ease installation, contributing to faster commissioning in multi-dwelling or light commercial retrofits. The NEMA 3R enclosure enhances outdoor durability, lowering enclosure maintenance and extending service life in exposed environments. Overall, this solution reduces downtime, simplifies procurement, and supports regulatory compliance with EUSERC and UL listings.

FAQs
Yes. CMBE24B125TSR is designed as a retrofit meter breaker compatible with Type CH breakers and Type CH panel configurations. It supports retrofits in residential metering installations, offering a 125A main with 4 circuits and an overhead feed, which helps streamline field wiring and maintain code compliance during panel upgrades.
Key ratings include 125A main, 120/240 V, and 4 circuits with a single socket. The unit uses aluminum bus and is configured for overhead feed in a NEMA 3R enclosure. Physical dimensions are approximately 34.5 in (length) Ă— 6.5 in (height) Ă— 14.7 in (width), with a weight around 45 lb, enabling manageable installation in retrofit metering enclosures.
The CMBE24B125TSR features a NEMA 3R enclosure, making it suitable for outdoor and semi-exposed installations. Its design supports surface mounting, which simplifies retrofits in exterior meter centers or protected outdoor panels often found in multi-dwelling, commercial, and light-industrial settings.
This unit carries UL Listed and EUSERC Approved certifications, which are critical for utility approvals and compliance with regional electrical codes. These certifications, combined with the NEMA 3R enclosure, help ensure reliable operation in diverse environments and support project qualification and asset management programs.
The retrofit-ready design reduces installation time and field wiring complexity, cutting labor costs and downtime during metering upgrades. The durable enclosure and long warranty (limited lifetime) support lower maintenance costs, while UL and EUSERC certifications help minimize regulatory risks and accelerate project sign-off, delivering a favorable total cost of ownership over the asset lifecycle.
