Eaton’s oil well controllers are supplied in a rugged NEMA 3R aluminum enclosure with gasketing to seal out moisture and dust. The enclosure is built with a dual door design to allow for quick access to all control equipment. Quick-release trunk latches allow for access to the inner compartment, making available to the operator the hand-off auto selector switch, the starter overload reset button and the linear operating handle mechanism. The inner door provides access to the starter components. For trouble-free operation, the handle is directly mounted to the HMCP adjustable, magnetic-only motor circuit protector. A defeater mechanism is also supplied to allow authorised access to the starter components. A mounting bracket is attached to the top and bottom of the enclosure for sturdy mounting of the controller.
