Power-pole adder kits
One single- or double-circuit power pole kit may be field added to a basic 2- or 3-pole Type S contactor or starter, Size 0–2, or a
30–60 A lighting contactor. The ratings for these power-pole adders correspond to the NEMA contact ratings found in the contactor
and starter section or lighting contactor section. A 2- or 3-pole contactor or starter will accept only one single- or double-circuit
unit. A power pole cannot be used on 4- or 5-pole devices or devices which are mechanically interlocked.
For adding a power pole to a Size 2 or 60 A device, a coil change is required. When adding Sizes 0 to 2 power pole kits to a Size 3
to 7 or 100 to 800 A device, an adapter bracket (9999 SBT 1) is required.
The Class 9999 Types SB 6 to SB 15 power pole kits are suitable for copper wire only. Types SB 21 to SB 25 are supplied with
lugs suitable for copper and aluminum wire.

Control circuit fuse holders
The control circuit fuse holder is designed to be used on Type S contactors and starters, Sizes 00 to 7, when either one or two
control circuit fuses, 600 V maximum, are required. The Type SF 3 and SF 4 fuse holders accept standard 600 V Bussmann Type
KTK or equivalent fuses (10 mm x 38 mm), 6 A maximum. Type SFR 3 and SFR 4 fuse holders accept Class CC 600 V Bussmann
Type KTK-R or equivalent fuses only.

Transient suppression modules
The transient suppression module is designed to be used where the transient voltage, generated when opening the coil circuit,
interferes with the proper operation of nearby integrated or solid-state control circuits. The module consists of a RC circuit and is
designed to suppress the coil voltage transients to approximately 200% of peak coil supply voltage. The module is wired across
the coil for Type S, Sizes 00 to 5 and is designed for coil voltages of 120 V only.
