Abb tl12412c Main Lug Load Center 125A 3-phase 12-circuit

Product Description

The ABB tl12412c is a 3-phase main lug load center rated for 208Y/120 VAC service at 125 amps with a 22 kA interrupt rating. It is built for commercial electrical distribution and high-rise residential applications where a factory-installed main lug configuration is required. The enclosure is NEMA 1 rated with a NEMA 4 rated enclosure box, and the unit accommodates 12 circuits using THQL-type breakers. The galvanized box and tin-plated copper stabs are designed for long-term reliability under heavy-use conditions. Licensed electricians handle installation and termination of this load center during new construction or service upgrades.

This load center is suited for commercial buildings, multi-tenant facilities, and high-rise residential construction where 3-phase 208Y/120 VAC distribution is required. The 4-wire wiring configuration supports balanced three-phase loads and neutral connections. With 12 spaces and flush mounting, it fits standard recessed panel installations. Wire entry accepts conductors from 6 AWG to 2/0 AWG, covering a wide range of feeder sizes typically found in commercial sub-panel applications.
