SPECIAL TO THIS PRODUCT: INCLUSIONS: SMD-20 and SMD-40 Mountings Complete mountings include fuse-unit end fittings. Fuseunit end fittings for SMD-40 Power Fuses include Silencer. A choice of connector arrangements is available with complete mountings as listed in the table on page 12. Specify the connector arrangement desired by adding the appropriate suffix letter to the catalog number of the selected mounting. Each overhead pole-top style SMD-20 Mounting includes mounting bracket and hardware. EXCLUSIONS: SMD-20 and SMD-40 Mountings Mountings do not include fuse units. SM-4 and SM-5 Mountings Complete mountings and live parts do not include holders or refill units. Complete mountings and live parts do not include connectors. Various connectors are available as listed in the table on page 13. Specify quantity and catalog number of connectors desired. SPECIFICATION DEVIATIONS: SMD-20 and SMD-40 Mountings Live parts are not available separately for SMD-20 and SMD-40 Power Fuses. Station style SMD-20 and SMD-40 Mountings are offered with a choice of Cypoxy a or porcelain station post insulators. The standard insulator color is gray. When mountings are to be provided with special insulators, consult your nearest S&C Sales Office for availability. Station style mountings (except station right-angle style) can be supplied less insulators; add suffix -Z1 to the catalog number. Supersedes Specification Bulletin dated SPECIFICATIONS ç3 Station style mountings (except station right-angle style) of a given voltage rating can be provided with insulators of the next lower voltage rating add suffix -Z2 to the catalog number, or the next higher voltage rating add suffix -Z3 to the catalog number.f Station style mountings cannot be supplied less bases. Station style mountings (except station right-angle style) can be supplied with tin-plated terminal pads. To specify, add suffix -Z5 to the catalog number. Overhead pole-top style SMD-20 Mountings cannot be supplied less insulators. SM-4 and SM-5 Mountings SM-4 and SM-5 Mountings are offered with a choice of Cypoxy or porcelain station post insulators. The standard insulator color is gray. When mountings are to be provided with special insulators, consult your nearest S&C Sales Office for availability. Mountings can be supplied less insulators; add suffix -Z1 to the catalog number. Mountings of a given voltage rating can be provided with insulators of the next lower voltage rating add suffix -Z2 to the catalog number, or the next higher voltage rating add suffix -Z3 to the catalog number.f Mountings can be supplied less bases but including insulators, add suffix -Z4 to the catalog number. Mountings can be supplied with tin-plated terminal pads. To specify, add suffix -Z5 to the catalog number. Disconnect style parallel SM-5 Power Fuses are furnished with aluminum terminal pads as a standard feature. a Cypoxy is the S&C trademark for S&C s cycloaliphatic epoxy resin system. Cypoxy is nontracking, self-scouring, nonweathering... there s never a compromise of insulation integrity. S&C Cypoxy station post insulators meet or exceed the electrical and mechanical-strength requirements established in ANSI Standard C29.9 (1983) for porcelain standardstrength station post insulators. f Mountings rated 4.8 kv or 7.2 kv cannot be provided with lower rated insulators. Fuse mountings rated kv provided with insulators of the next lower voltage rating will be furnished with porcelain station post insulators rated 7.2 kv, T.R. No Fuse mountings rated kv provided with insulators of the next higher voltage rating will be furnished with porcelain station post insulators rated 46 kv, T.R. No S&C Power Fuses Types SM and SMD are manufactured in accordance with a quality system certified to ISO 9001:0, and they are Rural Utilities Service (RUS) approved. Page 1 of

Page 2 of SM-4 and SM-5 Mountings For the standard warranty contained in seller s standard conditions of sale (as set forth in Price Sheet ) to apply to live parts when ordered separately, the live parts must be assembled on mountings in accordance with S&C Instruction Sheet The standard warranty contained in seller s standard conditions of sale (as set forth in Price Sheet ) does not apply to S&C SM Mountings when installed in conjunction with fuses of other than S&C manufacture.

3 How to Order a Complete Power Fuse Types SMD-20 and SMD Obtain the catalog number of the desired mounting from the column entitled, Mounting on page 4. Note: Live parts for SMD-20 or SMD-40 Power Fuses cannot be ordered separately. 2. Obtain the catalog number of the applicable SMU-20 or SMU-40 fuse unit from the tables on pages 6 through 8, taking care to match the voltage rating of the fuse unit to that of the mounting. 3. Select the desired connector arrangement from the table on page 12. Add the indicated suffix letter to the catalog number of the mounting selected in Step 1, above. 4. Obtain the catalog number of desired conversion kits, parts, and maintenance supplies from the tables listed on page 14. How to Order Handling Tools Obtain the catalog number(s) of recommended handling tool(s) from the table on page 14. Refer to Specification Bulletin Types SM-4 and SM-5 1.
