Circuit-Isolator II™ Disconnect

Type DS-1 Switch Operator

The Type DS-1 Switch Operator is an economical, low-speed operator designed for use with the Circuit-Isolator II Disconnect. It is also suitable for use with disconnects of other manufacture.

An electric motor drives a geared torque-transfer system, opening and closing the disconnect in approximately six seconds. The Type DS-1 Switch Operator includes a mechanical decoupling feature which allows the operator to be exercised while the disconnect remains in the open or closed position-permitting operational checkout of the control scheme without affecting the load. A removable manual operating handle is included for manual operation in case control power is lost.

The Type DS-1 Switch Operator is furnished with a weather-proof, dustproof, painted mild-steel enclosure as standard, but can be optionally specified with an aluminum or stainless-steel enclosure for use in coastal or harsh environments. A space heater is furnished as standard.

The Type DS-1 Switch Operator includes four adjustable auxiliary contacts which follow the position of the vertical operating pipe.

Optional Features Include:

• Key interlocks — locks disconnect open and disconnects motor control.
• Aluminum or Stainless Steel enclosure.
• Operation counter.
• Local-Remote blocking switch.
• Auxiliary contacts. Up to ten auxiliary contacts for use in remote monitoring and operation of the disconnect.
