Abb tm42420c Minimod Load Center 600A Mlo N3R

Product Description

The ABB tm42420c is a MiniMod combination metering and load center assembly rated for 600 amps main lugs only (MLO) operation. Designed for utility metering and branch circuit distribution, this unit features three 200-amp meter positions with a ringless hub configuration. The NEMA 3R-rated enclosure makes it suitable for outdoor or exposed installation where weather resistance is required. Licensed electricians install this type of assembly in residential and light commercial settings where a compact, integrated meter-main solution is needed.

This unit is applied in multi-tenant residential developments, manufactured housing communities, and light commercial properties that require multiple metered services in a single enclosure. The ringless meter socket configuration is common in utility districts that specify ringless-style meter acceptance. The 600A MLO configuration feeds downstream through the three 200A meter positions, consolidating what would otherwise be multiple separate enclosures into one compact assembly.

Key Features

• 600-amp main lugs only (MLO) rating for direct service entrance connection
• Three 200-amp meter positions for multi-tenant or multi-service applications
• Ringless hub configuration meeting common utility metering requirements
• NEMA 3R enclosure rating for outdoor and weather-exposed installation
• MiniMod design integrates metering and load distribution in a single assembly

Compatibility

Designed as an OEM-style replacement or direct installation unit for multi-meter MiniMod load center assemblies requiring a 600A MLO, three 200A meter, NEMA 3R, ringless hub configuration.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility requirements. De-energize the service entrance conductors and confirm the utility has disconnected power before opening or servicing the enclosure. Ringless meter sockets require coordination with the serving utility for meter installation and removal. Verify all conductor landing and torque requirements per the manufacturer labeling and NEC Article 230 for service entrance equipment.
