These DC mill type contactors are designed for heavy industry service and are suitable for use on moving machinery. The contactors listed in this section are for surface mounting on steel panels and front-of-panel wiring. The power stud assembly is mounted on the side of the contactor, rather than as part of a separate mounting kit. The contactors feature forged steel armature levers and magnet frames for superior physical strength. Self lubricating bearings eliminate the need for lubricating the contactor.
