Used in crane bridge, trolley, and heavy industrial DC motor control applications, the Square D EC&M Class 7004 Type MGO-1 is a single-pole, normally open LINE-ARC DC magnetic contactor rated NEMA Size 5. The assembly part number is 51019-332-04 as shown on the shipping label, with the installed operating coil marked 51019-243-93 and rated 230/240 VDC. Per published Square D Class 7004 specifications, the NEMA Size 5 MGO-1 contactor is rated for 600 volts DC maximum and 300 amperes continuous duty (8-hour rating), with a single normally open power pole. The unit is manufactured in Mexico, consistent with Square D / Schneider Electric production markings visible on the frame casting. The iridescent gold metal arc chute plate is present and marked EC&M 1435 No. 5, confirming the NEMA Size 5 arc suppression assembly. The contactor body, coil housing, and mechanical linkage components are all present and visible. Brass power terminals are intact. This contactor type is a direct replacement or spare for Square D Class 7004 Type M LINE-ARC DC contactor applications across mill-duty, crane hoist, and industrial drive systems requiring single-pole DC switching at the NEMA Size 5 current rating. Part is sold as-is surplus.
