Separate Enclosures Class 9991

Separate enclosures can be used with open style devices for field assembly of enclosed controls.
These enclosures, plus the open style components, are equivalent to a factory-assembled device.
Separate enclosures are to be used only with the equipment listed below:
• NEMA 4 and 12, Class 9991 Separate Enclosures for Type S devices
Standard devices come with closing plates. See the selection chart below for the specific number
of closing plates on various enclosures. For applications requiring enclosures without closing
plates, consult your local Schneider Electric representative.
• NEMA 3R Enclosures for field assembly of equipment for outdoor applications
Standard devices come with three closing plates, a reset mechanism, and a predrilled panel. For
Type SCA11 conduit connection to the top of these enclosures, select watertight hubs from Digest Section 16 in
NEMA 12 Enclosure
accordance with applicable code requirements. Square D™ brand NEMA 12 enclosures can also
be modified for outdoor use. For details, refer to the NEMA 12 enclosure modification information
on page 4.
NOTE: Not for use in high-corrosive outdoor locations or sea coast environments.
• NEMA 4X Enclosures for Type S devices, Sizes 0–2 and 30–60 A
Standard devices come without closing plates. Cover-mounted control units for NEMA 4X separate
enclosures are available as a factory modification only.
Cover-mounted control units, Class 9001 Type K or Type SK, can easily be installed into the openings
when the closing plates are removed from NEMA 4, 12, and 3R enclosure covers. Refer to Table 37 on
page 13.

Separate Enclosures Class 9991

Addition of Control Circuit Transformer—Oversize NEMA 1, 4, and 12/3R Enclosures

NEMA Contactors and Starters: Class 8502 or 8536, Type S, NEMA Size 0, 1, 1P, or 2
The Class 9991 oversize enclosures listed in Table 6 accept an open-style contactor or starter, along
with a fused control-circuit transformer (Form F4T), for field assembly of enclosed controllers. Knock-
outs in the cover of the Class 9991 Type SCG1 enclosure provide for field addition of Class 9999
rectangular cover-mounted control units. All other Class 8502 and 8536 enclosures include a panel
with space and drilling for an open-style device and a fused control-circuit transformer. In addition,
each cover includes three closing plates for easy installation of Class 9001 Type K or SK control units.
Lighting Contactors: Class 8903 Type L and LX (20 A) and Type S (30 and 60 A)
Type SCW4 Oversize enclosures for open-style electrically and mechanically held lighting contactors include a
NEMA 4 Enclosure drilled panel with space for the following: an open-style contactor, a fused control-circuit transformer
(Form F4T), and an auxiliary relay for use with single-pole pilot devices (Form R6). When an auxiliary
relay is required, use a Class 8501 Type XO11 relay. Three closing plates come standard for easy
installation of Class 9001 Type K or SK control units.
NOTE: If a Form F4T control transformer (with or without cover control units) is required on a
Class 8903 Type SMO, 30 A, electrically held lighting contactor, then a Class 9991 Type SCG1,
NEMA 1 separate enclosure can also be used.

Table 50: Power Pole Adders

One single- or double-circuit power pole kit can be field added to a Size 0–2, basic two- or three-pole
Type S contactor or starter, or to a 30–60 A lighting contactors. See the table below for selection. The
ratings for these power pole adders correspond to the NEMA contact ratings found in Section 16 of the
Digest. A two- or three-pole contactor or starter will accept only one single- or double-circuit unit. A
power pole cannot be used on four- or five-pole devices or on mechanically interlocked devices.
Adding a power pole to a Size 2 or 60 A device requires a coil change. Select a 4–5 pole coil from the
selection tables on page 9, or specify Form Y118 as noted in the footnote below. When adding a
Size 0–2 power pole kit to a Size 3–7 or 100–800 A device, an adapter bracket (Class 9999 Type
SBT1) is required.
The Class 9999 Types SB6–SB15 power pole kits are suitable for use with copper wire only.

NEMA Contactors and Starters Mechanical Interlocks and Mounting Brackets
Accessories Class 9999

Mechanical Interlock

General: Type S contactors or starters can be mechanically interlocked so that only one device is
energized at a time. The mechanical interlock is an interference (non-jamming) type, locking at the
beginning of the stroke of any starter or contactor.
Type S Sizes 00–2: The mechanical interlock is mounted on the underside of the reversing baseplate.
Two pins extend from the mechanical interlock through openings in the baseplate and engage the
contact carrier of each contactor. Two styles of mechanical interlocks are used: one version for three-
pole contactors, and another version for four- or five-pole contactors.
NOTE: When adding a power pole to the left-hand side of an existing Size 0–2 three-pole reversing
Type SM1
contactor, a new mechanical interlock must also be installed. When added to the right-hand side
only, the power pole will not be mechanically interlocked with the left-hand contactor.
Type S Sizes 3–4: The mechanical interlock is separate from the mounting pan on Sizes 3–4. Cams
on the mechanical interlocks are operated by the contact carrier of each contactor. The mechanical
interlock is attached to the underside of the two contactor baseplates on Sizes 3–4.
Table 65: Mechanical Interlock for Two Contactors
The following mechanical interlock kits can be used to interlock 2–5 pole contactors. Mechanical
interlocks for horizontal and vertical arrangement are listed in various pole arrangements.
