AR116 34.5kV grounded wye, 150kV Polymer, Horizontal AR Switch



34.5kV grounded wye, 150kV LIW, 900A, Horizontal Three-Phase Gang Operated Loadbreak Switch.

  • The Type AR switches have a clockwise opening and are operable by torsional or reciprocating controls as well a hookstick operation option (full-length down-the-pole control or crossarm-mounted hook stick-operation control). The hookstick operation minimizes installation time, reduces possible vandalism, eliminates control adjustments.
  • All three phase switches feature a four-link overtoggle mechanism to assure locked closed blades, mechanical advantage for easier open and close operation, and""snap"" feedback to the operator.

Refer to the Catalog Numbering System resource below for each configuration option (Positions 4 to 13).
