Mounting Arrangements S&C Three-Pole Alduti-Rupter Switches with Power s are available in Standard Mounting Arrangements as described in S&C Data Bulletin 77-80. Departures from Standard Mounting Arrangements are also available and fall into three categories:. Standard Minor Modifications of Standard Mounting Arrangements are those which are so frequently encountered that they are included on S&C s basic erection drawings (ED). Applicability of Standard Minor Modifications are listed in the table on page 8. The applicable Standard Minor Modifications may be specified by adding the appropriate Suffix -S to the erection drawing (ED) number. 2. Special Minor Modifications of Standard Mounting Arrangements are those which include such departures as special base drillings or special mounting brackets for operating-mechanism components. For this category of special, S&C will prepare a custom erection drawing (ED) based on the Standard Mounting Arrangement erection drawing (ED). Switches will be supplied with an operating mechanism for the Special Minor Modification of a Standard Mounting Arrangement. 3. Special Mounting Arrangements are those which involve complete departures from the Standard Mounting Arrangements brought about by customizing an S&C Alduti-Rupter Switch with Power s to fit the user s structure. Custom erection drawings (ED) will be provided as required. EXCLUSIONS: Alduti-Rupter Switches with Power s do not include connectors. Various connector arrangements are available as listed in the table on page 3. Specify the quantity and catalog number of connector arrangement desired. Alduti-Rupter Switches with Power s do not include holders, refill units, or fuse units.

Alduti-Rupter Switches with Power s Type SM does not include SM Refill Units or SM Holders. The catalog number of the holder may be obtained from the same horizontal line in which the switch is listed. Alduti-Rupter Switches with Power s Type SMD do not include SMD Units or SMU-20 Units. In selecting a refill unit or fuse unit, watch these points: Alduti-Rupter Switches with Power s Type SM match refill unit type to holder type. Alduti-Rupter Switches with Power s Type SMD select fuse unit of the type indicated. Refill units and fuse units are listed separately. In selecting a refill unit or fuse unit, consider the following:. Description SM-4, SM-5, SMD-A, SMD-2C, or SMU 20 2. Voltage rating 3. Ampere rating 4.. POWER OPERATION: Power operation or, if desired, remote supervisory control may be provided for S&C Alduti- Rupter Switches with Power s by the addition of the appropriate S&C Switch Operator Type AS-A, or AS-0, or by adding an S&C 680M Automatic Switch Operator. S&C Switch Operators Types AS-A and Type AS-0 are for power operation of Alduti-Rupter Switches with Power s with rotating-type and reciprocating-type operating mechanisms, respectively. These switch operators are high-speed operators, with operating times not exceeding.75 second and.2 seconds maximum, respectively. This high operating speed provides sufficient moving-contact velocity in the interrupters to ensure full interrupting capability and long operating life. 680M Automatic Switch Operators are available in two versions torsional, for rotating-type mechanisms, and reciprocating, for reciprocating-type operating mechanisms. Both versions operate in.5 seconds. This high operating speed is fully compatible with the movingcontact velocity required by the interrupters to ensure full interrupting capability for the applicable switch styles and mounting arrangements. Power operation is available for certain mounting arrangements only. Consult the nearest S&C Sales Office for availability. For additional details concerning S&C Switch Operators Types AS-A or AS-0, refer to Specification Bulletin 769-3. For additional details concerning M Series Switch Operators, refer to Specification Bulletin 045M-3. WARRANTY QUALIFICATIONS: The standard warranty contained in S&C s standard conditions of sale, as set forth in Price Sheet 50, does not apply when Alduti-Rupter Switches with Power s are power operated using a switch operator other than S&C manufacture. 2 S&C Specification Bulletin 77-3
