ABB TC10323R – Frequently Asked Questions

1) Can I use this ABB double throw switch as a manual generator transfer switch?
That is exactly what a double throw switch is for. The ABB Spec-Setter double throw safety switch moves a load between two sources, normal utility and a standby generator, by throwing the handle from one position to the other. It is a manual transfer device, not an automatic transfer switch, so someone has to be at the switch to make the change. Rated 120/240V, and the NEMA 3R enclosure lets it sit outdoors next to the meter or the generator pad.
2) Does the ABB Spec-Setter double throw switch take fuses?
No. It is a nonfusible switch, so there are no fuse clips inside and no fuses to buy. Overcurrent protection has to come from somewhere else in the system, typically the upstream breaker on the utility side and the generator's own breaker on the standby side. If your drawing calls for fused disconnect duty at this point, you need a fused double throw instead.
3) What amperages does the ABB TC series double throw switch come in?
Two: 100 amp (ABB part TC10323R) and 200 amp (TC10324R). Both are 2-pole, 120/240V, nonfusible, in the NEMA 3R outdoor enclosure. Size it to the service or the feeder it is transferring, not to the generator alone, since the same switch carries utility power in the normal position.
4) Will a 2-pole 120/240V double throw switch work on a 3-phase 208V or 480V system?
No. This is a 2-pole switch rated 120/240V, which suits single phase 3-wire residential and light commercial services. A 3-phase feeder needs a 3-pole switch rated for that system voltage. For 3-phase unfused disconnect duty ZenSupply carries the Square D VisiPacT Heavy Duty Unfused Safety Switch in NEMA 1, though note that is a single throw disconnect, not a transfer device.
5) What should I use instead of the ABB NEMA 3R switch in a washdown or coastal environment?
NEMA 3R, which is what the ABB TC10323R and TC10324R carry, is rain-tight for ordinary outdoor exposure but is not the rating for hose-down, chemical, or salt-air service. The Square D VisiPacT VH324NDSGL is built in a NEMA 4X stainless steel enclosure, which is the rating specified for washdown areas, food processing, and corrosive coastal installations. Note the trade in function: the VisiPacT VH324NDSGL is a fused single-throw switch, not a double throw, so it disconnects a feed rather than transferring between two sources.
6) Can this switch be mounted outside on an exterior wall?
Yes. The enclosure is NEMA 3R, which is the outdoor rain-tight rating used for exterior wall and pad-mounted disconnects. Keep the knockouts you use on the bottom or use rain-tight fittings on the top so water cannot track in. If the location is a washdown or coastal corrosive area, a 3R painted enclosure is not the right choice there, a stainless NEMA 4X such as the Square D VisiPacT in 4X stainless handles that duty.
7) How is the ABB double throw different from the Eaton K-series double throw switch?
Both are non-fused double throw switches for source transfer, but the enclosure is the deciding difference. The ABB Spec-Setter TC comes in NEMA 3R for outdoor mounting, while the Eaton Heavy-Duty Double-Throw Non-Fused switch we stock is a painted steel NEMA 1, which is indoor dry-location only. If the disconnect lives outside at the meter or generator, the 3R is the one that can go there.
8) Does a double throw switch switch the neutral too?
Not on this one. It is a 2-pole switch, so it breaks and transfers the two ungrounded conductors of a 120/240V single phase service. The neutral runs through solid and is not switched. If your generator installation requires a switched neutral because of how the generator is bonded, a 2-pole device will not satisfy that, you need a 3-pole switched-neutral arrangement.
9) What is the ABB part number for the 100 amp NEMA 3R double throw switch?
TC10323R. That is the 100A, 2-pole, 120/240V nonfusible double throw in the NEMA 3R outdoor enclosure from ABB's Spec-Setter line. The 200A version in the same family is TC10324R.
10) Is the Eaton K-series double-throw switch the same thing as the ABB Spec-Setter double throw switch?
They perform the same switching job but they are different product lines. The ABB unit is part of the Spec-Setter line, offered at 120/240V with 100 ampere and 200 ampere ratings under part numbers TC10323R and TC10324R, in a NEMA 3R enclosure. The Eaton is a K-series heavy-duty double-throw non-fused switch in a painted steel NEMA 1 enclosure. Because the enclosure ratings differ, they are not drop-in equals across installations - confirm whether the mounting location is indoor or exposed before cross-ordering, and note that enclosure footprints and conduit entry differ between manufacturer lines, so an existing backplate or conduit stub-up may not line up.
11) I manage a building and need a disconnect I can lock open for service, does this do that?
A double throw safety switch has three handle positions, source one, off, and source two, so yes it can isolate the load entirely in the center position. Where it differs from a plain disconnect is that it also feeds an alternate source, which is why it is used at generator hookups rather than as a simple single-source disconnect. If you only need to kill power to one piece of equipment and never transfer it, a standard single throw safety switch is the simpler and more appropriate part.
