Schneider Electric QO312ML1RB 3 Phase Load Center 125A 240V

Product Description

The Schneider Electric QO312ML1RB is a QO-series three-phase load center designed for use in commercial and light industrial electrical distribution systems. Rated at 125 amperes and 240 volts AC, this main lug only (MLO) panel supports up to 12 circuit spaces and carries a 65 kiloampere interrupting rating, making it suitable for installations where fault current capacity is a critical design parameter. The convertible main type configuration allows the panel to be adapted to accept a main breaker if field conditions require it. A licensed electrician installs and commissions this type of equipment.

This load center is intended for three-phase electrical distribution in applications requiring a compact, rain-resistant enclosure. The NEMA 3R rating makes it appropriate for outdoor or semi-exposed locations where protection from rain and sleet is necessary. With 12 maximum spaces and 12 maximum circuits, it fits light commercial service entrance or sub-panel applications where a moderate circuit count is sufficient. The panel ships as a single unit and is manufactured in the United States.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the upstream service or feeder completely before opening the enclosure or making any connections. Verify that the available fault current at the installation point does not exceed the 65 kA interrupting rating of this panel. Torque all lugs and bus connections to the values specified on the panel label and in the manufacturer installation instructions.
