DESIGN CHARACTERISTICS Cabinet The USCO motor operator comes equipped with a weatherproof stainless steel or aluminum enclosure. Continuous welding at the seams provides a weatherproof seal to protect electrical components from dirt and moisture for long life and serviceability. All cabinets are equipped with provisions for padlocks to prevent injury or tampering.

Motors The electric motor utilized in the USCO motor operator is sized to provide adequate torque for large switches while maintaining appropriate operating speed. Gearbox Gearboxes include an anti-backdrive worm gear set. The anti-backdrive worm gears prevent unwanted switch movement during operation and add an extra level of safety for switch operators and crews. Controls The USCO motor operator comes standard with local controls that include a stop command effective at any point in the switch’s open/close cycle. Provisions to connect remote operation controls are included. A local/remote selector switch is available upon customer request.

Auxiliary Switches The USCO motor operator comes standard with 10 infinitely adjustable auxiliary decks for electrically interlocking with other substation equipment or remote position indication. Each deck includes one NO contact and one NC contact wired to easily accessible terminal blocks for customer use. For customers requiring more contacts, the auxiliary array is expandable to 20 decks suitable for customer use.
