ABB TGN3321R – Frequently Asked Questions

1) Can the ABB Spec-Setter TGN safety switch be mounted outdoors next to a condenser?
Yes. The Spec-Setter TGN series comes in a NEMA 3R enclosure, which is the outdoor rating for protection against rain and falling water, so it is suited to an AC condenser or heat pump disconnect on an exterior wall or pad. It is a general duty switch intended for residential and light commercial work, not an industrial heavy duty application.
2) What amperage sizes does the ABB TGN non-fusible safety switch come in?
Four sizes: 30A (TGN3321R), 60A (TGN3322R), 100A (TGN3323R) and 200A (TGN3324R). All four are 3-pole, non-fusible, 240V general duty switches in a NEMA 3R enclosure. Size the switch to the equipment's nameplate load and the upstream overcurrent protection, since a non-fusible switch provides no overcurrent protection of its own.
3) Does a non-fusible disconnect like the ABB TGN protect the circuit, or do I still need fuses or a breaker?
It does not protect anything. The TGN is a non-fusible switch, so it only opens and closes the circuit for service isolation and lockout. Overcurrent protection has to come from the upstream breaker or a fused disconnect. If the equipment nameplate calls for maximum fuse size rather than maximum breaker size, you want a fused switch instead.
4) Can I use the ABB TGN 3-pole switch on a 208V or 240V three-phase motor?
Yes, within its ratings. It is a 3-pole switch rated 240V, which covers 240V and 208V three-phase systems. It is not rated for 480V; a 480V three-phase disconnect needs a 600V-class switch such as the Square D VisiPacT heavy duty line. On single-phase 240V loads you simply land the two hot legs on two of the three poles.
5) I need a non-fused disconnect but the switch is going inside a mechanical room, not outdoors. Is there an alternative to the ABB TGN?
The ABB Spec-Setter TGN series is a general duty non-fusible switch in a NEMA 3R outdoor enclosure, which is built to shed rain on exterior walls. For an indoor mechanical room where weather exposure is not a factor, the Square D VisiPacT heavy duty unfused safety switch VHU361N is a NEMA 1 enclosure unfused switch. Both give you a straight on/off isolation point with no fuses to stock or replace; the difference is the enclosure environment and the heavy duty versus general duty construction class.
6) My spec calls for overcurrent protection at the disconnect. Does the ABB TGN cover that, and what do I use if not?
No. The ABB Spec-Setter TGN is non-fusible, meaning it isolates the circuit but carries no fuses and provides no overcurrent protection of its own, so upstream protection has to come from elsewhere. If the drawing requires fuses in the disconnect itself, the Square D VisiPacT VH324NDSGL is a fused safety switch, and its NEMA 4X stainless steel enclosure suits washdown or corrosive locations rather than the standard outdoor duty the TGN 3R enclosure covers.
7) Will the ABB Spec-Setter TGN work as a generator transfer switch?
No. The Spec-Setter TGN is a single-throw 3-pole disconnect that simply opens and closes one set of line and load connections, so it cannot select between two sources. For a manual source-selection application you want a double-throw device such as the Eaton K-series double-throw non-fused safety switch DT-223UGK, which is also non-fused but is housed in a painted steel NEMA 1 enclosure and so is intended for indoor mounting rather than the outdoor exposure the TGN 3R enclosure handles.
8) What is the difference between a general duty switch like the ABB Spec-Setter and a heavy duty safety switch?
General duty, which is what the Spec-Setter TGN is, is built for residential and light commercial loads at 240V. Heavy duty switches are the industrial class, with higher voltage ratings and more enclosure choices. If you are feeding a plant motor, a 480V service, or a washdown or coastal location, look at heavy duty instead, for example the Square D VisiPacT unfused NEMA 1 switch for indoor industrial use or the NEMA 4X stainless VisiPacT fused switch for corrosive and washdown areas.
9) I need a disconnect that transfers between utility and generator. Will the ABB TGN do that?
No. The TGN is a single-throw on/off disconnect, not a transfer switch. For a manual changeover between two sources you want a double-throw switch such as the Eaton K-series heavy duty double-throw non-fused safety switch. Note that the Eaton unit is a NEMA 1 enclosure, so it is an indoor location only unless you house it.
10) Is a NEMA 3R switch okay for a coastal or washdown location?
NEMA 3R handles rain and outdoor exposure, but it is not a corrosion or washdown rating. For salt air, chemical exposure, or hose-down cleaning, go to a stainless 4X enclosure such as the Square D VisiPacT NEMA 4X stainless steel fused switch.
11) For a rooftop condenser at a coastal property, is the ABB TGN 200A the right disconnect or should I step up?
The ABB Spec-Setter TGN in NEMA 3R is a general duty switch rated 240V and sized to 200A at the top of the range, and it is intended for residential and light commercial outdoor equipment disconnects including HVAC and motor loads. On a salt-air coastal roof where the enclosure itself is the wear item, a stainless steel NEMA 4X switch such as the Square D VisiPacT VH324NDSGL is the heavier corrosion answer, though it is a fused heavy duty switch rather than a non-fusible general duty one, so the circuit design has to account for the fuses.
12) What is the closest equivalent to the ABB TGN3321R 30A switch from another brand?
The ABB TGN3321R is the 30 ampere version of the Spec-Setter 3-pole non-fusible NEMA 3R line. The nearest unfused equivalent among other brands is the Square D VisiPacT VHU361N unfused safety switch, with two differences to check against your spec: it is a heavy duty rather than general duty switch, and it comes in a NEMA 1 enclosure, so it is an indoor substitution only. If the disconnect is mounted outdoors, stay with the 3R-rated TGN.
13) Can I standardize on the ABB TGN across a portfolio of apartment HVAC units?
It is a reasonable fleet standard for that use. All four sizes, 30A through 200A, share the same general duty 240V 3-pole non-fusible design and NEMA 3R outdoor enclosure, so the mounting approach and the lockout procedure are consistent across the properties and only the ampere rating changes by unit size.
