These switches are furnished as com plete units including direct-coupled, chain-coupled, or pipecoupled handle; interphase barriers;d side barriers;d and any other operating-mechanism components required by the specifications for any Standard Mounting Arrange ment covered in S&C Data Bulletin Shaft extensions for three-pole switches will be furnished at no extra charge if they are specified on orders, together with the dimension required. EXCLUSIONS: All Alduti-Rupter Switches: Switches do not include connectors. Various connector arrangements are available as listed in the table on page 4. Specify quantity and cata log number of connector arrangement desired. SPECIFICATION DEVIATIONS: All Alduti-Rupter Switches: Switches cannot be pro vided with special insulators. Switches, regardless of voltage rating, cannot be sup plied for back connection. Higher or lower insulator voltage ratings for a switch of a given voltage rating are not available. Three-Pole Alduti-Rupter Switches: Three-pole switches can be supplied with an operating mechanism that conforms to the specifications of any minor modifi cation of the Standard Mounting Arrangements listed in S&C Data Bulletin Three-pole switches can be supplied with an operating mechanism that requires the preparation or re-use of a custom erection drawing of a special mounting arrange ment. Three-pole switches cannot be supplied less bases and/or less insulators. Three-pole switches can be supplied with tin-plated terminal pads. To specify, add suffix -Z5 to the switch catalog number. Single-Pole Alduti-Rupter Switches: Single-pole -ampere switches can be supplied less insulators add suffix -Z1 to the switch catalog number. Single-pole -ampere switches can be supplied less bases but including insulators add suffix -Z4 to the catalog number. Single-pole -ampere switches can also be supplied less bases and less insulators add suffix -Z1Z4 to the catalog number. Single-pole switches can be supplied with tin-plated terminal pads.

Duty-cycle fault-closing ratings define the ability to close the switch the specified number of times (one or two) against a three-phase fault with asymmetrical current in at least one phase equal to the rated value, with the switch remaining operable and able to carry and interrupt rated continuous current. 3 The two-time duty-cycle fault-closing ratings of the -ampere switches, when used in combination with Type SM-5S Power Fuses (S&C Alduti-Rupter Switches with Power Fuses), are,000 amperes at 4.1 kv; 43,500 amperes at kv; and 41,500 amperes at 7. kv. Twotime duty-cycle fault-closing ratings have not been established for the -ampere switches in combination with Type SM-5SS Power Fuses. 4 The one-time duty-cycle fault-closing rating of the -ampere switches, when used in combination with Type SM-5SS Power Fuses (S&C Alduti-Rupter Switches with Power Fuses), is 54,000 amperes at kv and 14.4 kv, hertz only (55,000 amperes on 7./1.47GrY-kV -hertz systems only). 5 Top and bottom front-connected.
