Abb TMMR6612RF Minimod Panelboard 600A Main Lug Nema 3R

Product Description

The ABB TMMR6612RF is a miniature modular panelboard configured with a 600-amp main lug only (MLO) arrangement and six 125-amp single-pole breaker spaces. Designed for metered or sub-feed electrical distribution, this unit ships in a NEMA 3R enclosure rated for outdoor or rain-sheltered indoor installations. The ringless meter socket configuration simplifies utility access and inspection. Licensed electricians and electrical contractors install this panelboard in residential, light commercial, and multi-tenant distribution applications where a compact, weather-resistant distribution point is required.

This panelboard is suited for outdoor service entrance or sub-panel installations where NEMA 3R environmental protection is required. The main lug only design means it is intended to receive feed from an upstream overcurrent device. The six 125-amp breaker positions support branch circuit distribution in applications such as detached structures, manufactured housing, and small commercial service points. The ringless meter configuration is commonly specified by utilities that require sealed meter sockets without a removable ring.

Key Features

• 600-amp main lug only (MLO) input — requires upstream overcurrent protection
• Six 125-amp single-pole breaker positions for branch circuit distribution
• NEMA 3R enclosure rated for outdoor use and protection against rain and sleet
• Ringless meter socket design for utility-compliant metering access
• Modular miniature panelboard format for compact installation footprint

Compatibility

Designed as an OEM-style modular panelboard for use in outdoor electrical distribution systems requiring a NEMA 3R rated, main lug only configuration with integrated metering capability.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all upstream feeds and verify absence of voltage before making any connections to the main lugs or branch breakers. The NEMA 3R enclosure must be mounted and sealed per manufacturer instructions to maintain its environmental rating. Utility coordination is typically required for ringless meter socket installations prior to energization.
