Alduti-Rupter® Switches
AS-1A and AS-10 Switch Operators
AS-1A Operator
AS-10 Operator
Types AS-1A and AS-10 Switch Operators are high-speed operators expressly designed for power operation of S&C Alduti-Rupter Switches.
- Type AS-1A Switch Operators are intended for use with S&C Alduti-Rupter Switches with rotating-type operating mechanisms and have a maximum operating time of .75 second.
- Type AS-10 Switch Operators are intended for use with S&C Alduti-Rupter Switches with reciprocating-type operating mechanisms and have a maximum operating time of 1.2 seconds. This high operating speed provides sufficient moving-contact velocity in the Alduti-Rupter Switch interrupters to ensure full interrupting capability and long operating life.
The operators’ high operating speed also provides adequate closing velocity for 25/34.5-kv and 34.5 kv Three-Pole Side-Break Integer Style and Three-Pole Vertical-Break Integer Style switches such that the Side-Break Integer Style switches have a one-time duty-cycle fault-closing rating of 15,000 amperes rms asymmetrical, and the Vertical-Break Integer Style switches have one-time duty-cycle fault-closing ratings of 20,000 or 30,000 amperes rms asymmetrical for switches rated 600 amperes or 1200 amperes, respectively.
Type AS-1A and Type AS-10 Switch Operators may be furnished with optional source-transfer control compatibility. This accessory permits use of the switch operator — along with a second switch operator and an S&C Type AT-2 Source-Transfer Control in weatherproof enclosure — to provide automatic source transfer for primary-selective overhead distribution systems.
