FAQs
Yes. The CMBE24B100TSR is designed for retrofit with Type CH EUCERC configurations. It supports 100A single-phase 120/240V operation across 4 circuits in 2 spaces and uses surface mounting in a NEMA 3R enclosure. The installation typically integrates the CSR2100BM main breaker and requires an overhead feed with a four-jaw connection, enabling a straightforward upgrade without a full panel swap.
This unit lists 22 kAIC and 35 kAIC interrupt ratings. These figures indicate the maximum fault current the breaker can safely interrupt, providing a margin for typical residential service faults and some higher-stress scenarios. Higher ratings help reduce the risk of equipment damage and improve overall system safety during short-circuit events.
Retrofit meter breaker installations in single-family homes and small multi-dwelling units benefit most. The unit supports Type CH EUCERC retrofits, 100A service, overhead feeds, and NEMA 3R outdoor or semi-protected locations. It minimizes panel changes, reduces wiring complexity, and accommodates future load expansion with four circuits across two spaces.
The CMBE24B100TSR is UL Listed and EUSERC Approved, signaling adherence to recognized safety and utility standards for electrical equipment used in residential service equipment. These certifications help ensure compliance with national and local electrical codes, streamline permit processes, and support safer, reliable operation in retrofits and new installations.
The unit’s UL/EUSERC certification, durable aluminum bus, and robust NEMA 3R enclosure contribute to long-term reliability and reduced maintenance. The retrofit design minimizes downtime and labor costs during upgrades, delivering a quicker return on investment for property owners, contractors, and facilities managers upgrading legacy service installations.
