Abb TMPSB4R Meter Main 400A 1-phase 42kaic Bottom Feed

Product Description

The ABB TMPSB4R is a single-phase meter main combination unit rated at 400 amps with a 42,000-ampere interrupting capacity (AIC). This assembly integrates a revenue-grade meter socket and a main breaker section into one enclosure, eliminating a separate disconnect. The main breaker section is configured for 1-phase, 3-wire service and features bottom-feed conduit entry. Units like this are typically installed at the service entrance by a licensed electrician where the utility meter and main overcurrent protection must occupy a single footprint.

This meter main combination is suited for residential or light commercial service entrance applications requiring a 400-amp main breaker in a single integrated enclosure. Bottom-feed configuration accommodates underground service lateral installations, a common arrangement in newer residential construction and in utility districts that require underground distribution. The 42kAIC interrupt rating meets the fault current requirements of most residential and light commercial services.

Key Features

• 400-amp main breaker section with 42kAIC interrupting rating
• Single-phase, 3-wire (1P-3W) configuration for standard residential service
• Integrated meter socket and main breaker in one enclosure
• Bottom-feed conduit entry for underground service lateral connections
• GE-style 400-amp main breaker section included

Compatibility

Designed as an OEM-style service entrance combination unit for single-phase residential and light commercial applications requiring an integrated meter main with a 400-amp main breaker and bottom-feed entry.

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 meter socket jaw configuration and sealing provisions meet their specifications before installation. De-energize the service lateral at the utility disconnect point before any work begins. Do not energize the unit until all conductors are properly landed, the enclosure is sealed, and the authority having jurisdiction has approved the installation.
