Abb TMPSB12R Meter Main Combo 1200A 1-phase 65ka

Product Description

The ABB TMPSB12R is a meter main combination module rated for 1200 amps in a single-phase, 3-wire configuration with a 65kA interrupt rating. This type of unit integrates a utility meter socket and main circuit breaker into a single enclosure, reducing the number of separate components required at the service entrance. It is configured for bottom feed, meaning service conductors enter from the bottom of the enclosure. Electricians and electrical contractors install these units at residential or light commercial service entrances where the utility meter and main disconnect are combined in one assembly.

Meter main combination modules like the TMPSB12R are typically installed at the point of service entry on residential structures, multi-family units, or small commercial buildings. The bottom-feed configuration suits installations where underground service laterals bring conductors up from below the enclosure. The integrated main breaker provides the required service disconnect without a separate disconnect switch or additional panel upstream.

Key Features

• 1200-amp main breaker rating for high-capacity service entrance applications
• 65kA interrupting rating meets requirements for high fault-current utility services
• Single-phase, 3-wire configuration for standard residential and light commercial service
• Bottom-feed design accommodates underground service lateral installations
• Integrated meter socket and main breaker in one enclosure reduces installation complexity

Compatibility

Designed as an OEM-style meter main combination unit for single-phase residential and light commercial service entrance applications where a 1200A main breaker and utility meter socket are required in a single assembly.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility requirements. Confirm with the serving utility that the meter socket form factor is approved before installation. De-energize the service and coordinate with the utility for meter pull before working on the service entrance assembly. Do not exceed the listed ampere and interrupt ratings for the installed service.
