Conditions of Sale STANDARD: The seller’s standard conditions of sale set forth in Price Sheet 150 apply, except as modified in the “Warranty Qualifications” section on page 3.

SPECIAL TO THIS PRODUCT:

INCLUSIONS: S&C Manual PMH Pad-Mounted Gear features directly operable accessible components.

Switches and fuses are clearly visible. Manual PMH models contain 600‑ampere external handle-operated Mini-Rupter® Switches for three-pole live switching of three-phase source circuits and 200‑ampere hookstick-operated S&C Power Fuses with Uni-Rupter® Interrupters for single-pole live switching of single-phase or three-phase load circuits. (These models offer a choice of S&C Type SML-20 and SML-4Z Power Fuses or Fault Fiter® Electronic Power Fuses. Fault Fiter Electronic Power Fuse mountings also accommodate a variety of single-barrel current-limiting fuses listed in Table 1 of S&C Information Bulletin 660-50.)

Enclosures meet the requirements of ANSI C57.12.28 (enclosure integrity). They are of free-standing, self-supporting construction—not for bolting directly to transformers—with provisions for cable entrance and exit through the bottom. Access to medium voltage is controlled by the Penta-Latch® Mechanism, which provides automatic door latching and permits padlocking only when the door is securely latched. The door can be opened only with a pentahead socket wrench or tool.

The enclosure roof is undercoated with an insulating “no-drip” compound. A resilient closed-cell gasket on the enclosure bottom flange protects the finish from being scratched during installation and isolates it from the alka linity of a concrete foundation. Enclosures are protected from corrosion by S&C’s olive green Ultradur® II Outdoor Finish.

A dual-purpose front barrier of fiberglass-reinforced polyester is provided for each switch and fuse. Where the National Electric Safety Code (ANSI Standard C2) applies, these barriers meet the requirements of Section 381G.

When the switch or fuse is in the Open position, this barrier can be inserted into the open gap to guard against inadvertent contact with live parts. Interphase and end barriers of the same material are provided with each switch and each set of fuses where required to achieve published BIL ratings. Additional barriers of fiberglass-reinforced polyester separate front and rear compartments and isolate the tie bus (where furnished).

Full-length steel barriers separate adjoining compart-ments (where applicable).

These PMH models are provided with a Grappler™ Handling Tool, if applicable; an instruction manual holder; and storage racks in the fuse-compartment doors for spare S&C Fuse Units or Refill Units and for the Grappler tool (storage for Fault Fiter Electronic Power Fuses or current-limiting fuses cannot be provided in these racks). A folding switch-operating handle, secured inside the switch-operating-hub pocket, is provided for each Mini-Rupter Switch. Terminal pads can accommo date a variety of cable-terminating devices for cable sizes through 1000 kc mil for switch and bus terminals, 4/0 maximum for fuse terminals. Each switch, fuse, and bus terminal is provided with a ground stud as is each ground pad.

All terminal pads can accommodate a variety of cable-terminating devices for cable sizes through 1000 kc mil for switch terminals, 4/0 maximum for fuse terminals. The cable-terminating devices must be equipped either with an offset spade-type compression terminal for bolting directly to the terminal pad or with a rod-type compression terminal for attachment to a connector of the type shown in Table 17 on page 20.

For applications where additional height is desired

2 S&C Specification Bulletin 662A-31 .

for increased elevation of ungrounded parts above the mounting pad and to facilitate cable pulling and installa-tion of cable-terminating devices, particularly where no cable pit is used, base spacers are available as listed in Table 4 on page 9.

While the interior of S&C Pad-Mounted Gear is protected from direct exposure to the elements, it is inherently designed for an outdoor environment and requires selection and application of cable-terminating devices accordingly. Terminations must incorpo-rate adequate leakage distance between the exposed conductor and the stress-relief cone across a surface of nontracking material (or a surface rendered nontracking by properly taping with a suitable material).

Furthermore, to maintain the rated BIL, the following minimum clearances are required: 6 inches (152 mm) at

14.4 kV and 71/2 inches (191 mm) at 25 kV from energized parts to electrical ground; 1 inch (25 mm) at 14.4 kV and 21/4 inches (57 mm) at 25 kV from energized parts to fiber-glass-reinforced polyester barriers; 1/2‑inch (13 mm) at

14.4 kV and 11/4 inches (32 mm) at 25 kV from terminator skirts to fiberglass-reinforced polyester barriers.

EXCLUSIONS: Three-phase units listed in Table 3 on pages 6 through 8 do not include the items listed in Table 4 on page 9 through 13, nor do they include the connector, fuse components, switch blades, or acces-sories listed in Table 5, Table 6, and Table 7 on page 14, or Table 14, Table 15 and Table 17 on page 20.

SPECIFICATION DEVIATIONS: Features or modifica tions other than those listed in Table 4 on page 9 cannot be accommodated. Specifically, the following modifications or additions are not available except in custom-design gear or other standard models of S&C gear:

● Relocation of components (switches and fuses)

● Inclusion, in fuse compartments, of surge arresters or porcelain cable-terminating devices

● Separable insulated 200- or 600‑ampere connectors

● Intermediate- or station-class surge arresters

● Mechanical interlocks

Certain minor departures from the optional features can be accommodated. For example, the user may use mounting provisions for different porcelain cable terminators in a switch compartment and bus compart-ment. Such deviations can be accommodated by a “minor modification.” Contact the nearest S&C Sales Office for availability.

APPLICATION NOTES: For application information and a guide to the selection of appropriate ampere ratings and speeds of S&C SML Power Fuses, and types and TCC curve parameters of control modules for Fault Fiter Elec-tronic Power Fuses, contact the nearest S&C Sales Office.

Switching with a Uni-Rupter Interrupter Manual PMH Pad-Mounted Gear features fuses with Uni-Rupter Interrupters for single-pole live switching of single-phase or three-phase load circuits on distribution systems rated 14.4 kV or 25 kV.

Complete ratings and capabilities of S&C Power Fuses with Uni-Rupter Interrupters as applied in manual PMH Pad-Mounted Gear are shown in Table 1 on page 5. The Uni-Rupter Interrupter is also capable of carrying and interrupting load currents up to and including the emergency peak-load capabilities of the associated SML power fuses. In addition to the load-drop-ping capabilities shown, the Uni-Rupter Interrupter is capable of interrupting transformer magnetizing currents associated with the applicable loads as well as line-charging and cable-charging currents typical for distribution systems of these voltage ratings.

The duty-cycle fault-closing capabilities shown for S&C Power Fuses with Uni-Rupter Interrupters repre sent the fault-closing capabilities of the fuse with the Uni-Rupter Interrupter when the fuse is closed with a purposeful thrust without hesitation. Following the specified number of such closings (two or three), the Uni-Rupter Interrupter will remain operable and able to carry and interrupt rated current.

. S&C Specification Bulletin 662A-31 3

A Note on Single-Pole Switching In single-pole switching of ungrounded-primary three-phase transformers or banks (or a single-phase transformer connected line to line), circuit connec-tions or parameters may, in some cases, produce excessive overvoltages. In particular, for the following applications above 22 kV, single-pole switching by any means—including the Uni-Rupter Interrupter—should be performed only under the conditions stated in italics

● Switching unloaded or lightly loaded delta-con-nected or ungrounded-primary wye-wye connected three-phase transformers or banks (or line-to-line connected single-phase transformers), rated 150 kVA or less three-phase, or 50 kVA or less single-phase— or of any kVA rating when combined with unloaded cables or lines—where maximum system operating voltage exceeds 22 kV (Single-pole switching should be performed only if each phase is carrying 5% load or more, or if the transformer or bank is tempo-rarily grounded at the primary neutral during switching.)

● Switching loaded or unloaded ungrounded-primary wye-delta connected three-phase transformers or banks—alone or combined with unloaded cables or lines—where maximum system operating voltage exceeds 22 kV (Single-pole switching should be performed only if each phase is carrying 5% load or more and if the lighting-load phase is always switched open first (or switched closed last), or if the transformer or bank is temporarily grounded at the primary neutral during switching.)

Recommended Voltage Ratings of Current‑Limiting Fuses for Use in S&C Pad‑Mounted Gear In general, current-limiting fuses should have a maximum voltage rating equal to, but not greater than 140% of, the system line-to-line voltage because for most applications, the fuses can be exposed to full system line-to-line voltage in clearing faults. Although there may be economic or space-saving incentives for using current-limiting fuses with voltage ratings “appro-priate for system line-to-ground voltage” (i.e., fuses with a voltage rating lower than line-to-line voltage but greater than or equal to maximum system line-to-ground voltage), S&C can recommend such use only in any of the following applications:

● Protection of single-phase transformers serving single-phase loads

● Protection of three-phase lateral circuits fed by a single-conductor shielded cable (provided each transformer on that lateral is individually fused so the current-limiting fuse serving the lateral will not be required to clear secondary faults)

● Protection of single-phase lateral circuits fed by a single-conductor shielded cable where the load is line-to-ground connected

Switching with a Mini-Rupter Switch Manual PMH Pad-Mounted Gear features Mini-Rupter Switches for three-pole live switching of three-phase circuits.

Complete ratings for Mini-Rupter Switches as applied in manual PMH Pad-Mounted Gear are shown in Table 2 on page 5. In addition to the load-dropping ratings shown, a Mini-Rupter Switch is capable of interrupting transformer magnetizing currents associated with the applicable loads as well as line-charging and cable-charging currents typical for distribution systems of these voltage ratings.

For applications on systems rated higher than 7.2 kV and involving load current with high harmonic content (such as rectifier load currents), refer to the nearest S&C Sales Office. The two-time duty-cycle fault-closing ratings shown for Mini-Rupter Switches define the ability to close the Mini-Rupter Switch twice 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 current.

WARRANTY QUALIFICATIONS: The standard warranty contained in the seller’s standard conditions of sale (as set forth in Price Sheet 150) does not apply to manual PMH Pad-Mounted Gear where fuse units, fuse unit end-fittings, holders, refill units, or switch blades of other than S&C manufacture are used in conjunction with S&C SML Mountings. Nor does it apply to manual PMH Pad-Mounted Gear where other than Fault Fiter Electronic Power Fuses, S&C Switch Blades, or the current-limiting fuses listed in Table 1 of S&C Informa-tion Bulletin 660-50 are used in conjunction with Fault Fiter Electronic Power Fuse mountings and S&C Holders designed therefor, or when current-limiting fuses are applied other than as set forth in the “Recommended Voltage Ratings of Current-Limiting Fuses for Use in S&C Pad-Mounted Gear” section.

① When switch blades are used in lieu of fuses, the Uni-Rupter Interrupter associated with these switches can carry and interrupt load currents up to and including the emergency peak-load capabilities of the SML power fuses, or up to 400 amperes at 14.4 kV and 200 amperes at 25 kV for Fault Fiter Electronic Power Fuses. Furthermore, the switches with a Uni-Rupter Interrupter have fault-closing ratings equal to those of S&C Power Fuses with Uni-Rupter Interrupters (refer to the “Application Notes” section on page 2). The momentary and one-second ratings of the switches equal the short-circuit ratings of the pad-mounted gear.
