Eaton DG321UGB-CSA – Frequently Asked Questions

1) Does this Eaton 30A general duty switch take fuses, or is it just a disconnect?
It is non-fusible, single-throw. There are no fuse clips inside, so the switch only opens and closes the circuit, it provides no overcurrent protection. Branch protection has to come from the upstream breaker or a separate fused disconnect. If you need local fuse protection at the equipment, choose a fusible general duty switch such as the ABB TG-Series Spec-Setter instead.
2) Will a 3-pole 240V safety switch work on a 480V three-phase motor?
No. The Eaton DG321UGB is rated 240V maximum, so it cannot be used on a 480V system. For 480 or 600V three-phase work, step up to a 600V rated unit such as the ABB TC-72367 heavy duty fusible switch or the ABB THN3365A, both rated 600V.
3) Can I mount this Eaton safety switch outdoors or in a wash-down area?
No. The enclosure is NEMA 1 painted steel, which is indoor only, protecting against dust and incidental contact but not rain, hose-down, or corrosion. For outdoor or wet locations pick a NEMA 3R or, for corrosive and wash-down duty, a stainless NEMA 4X unit like the Square D VisiPacT VH324NDSGL.
4) Can the Eaton DG321UGB 30A safety switch be used outdoors or in a wet location?
No. The DG321UGB uses a NEMA 1 painted steel enclosure, which is an indoor rating that guards against dust and incidental contact only. For outdoor, washdown, or corrosive environments, step up to a sealed enclosure such as the Square D VisiPacT heavy duty fused safety switch, which is supplied in a NEMA 4X stainless steel enclosure. Match amperage, voltage, and fusing to your circuit when you change enclosure types.
5) What is the closest unfused safety switch alternative to the Eaton DG321UGB if a heavy duty switch is required instead of general duty?
The Eaton DG321UGB is a general duty safety switch, non-fusible and single-throw, rated 30A at 240V with three poles in a NEMA 1 painted steel enclosure. When a specification calls for a heavy duty unfused disconnect in the same indoor NEMA 1 enclosure type, the Square D VisiPacT heavy duty unfused safety switch is the direct counterpart - it is also an unfused switch in a NEMA 1 enclosure, built to the heavy duty construction class rather than general duty. Confirm the amperage and voltage of the Square D unit matches the branch circuit before substituting.
6) I need fuse protection in the disconnect, not just a disconnect - what should I order instead of the Eaton DG321UGB?
The Eaton DG321UGB is non-fusible, so it opens the circuit but carries no fuses and provides no overcurrent protection of its own. If the design requires fuses inside the disconnect, the ABB TG-Series Spec-Setter is the general duty equivalent in a fusible configuration, keeping the same general duty construction class. For a heavy duty fusible switch, the ABB TC-72367 Spec-Setter is a 3-pole fusible switch rated 600V AC in a NEMA 1 enclosure, and the Square D VisiPacT fused switch comes in a NEMA 4X stainless enclosure for washdown or corrosive areas.
7) My drawing calls for a 600V disconnect - will the Eaton DG321UGB 3-pole switch satisfy it?
No. The DG321UGB carries a 240V rating, so it cannot be used on a 480V or 600V class system. For a 600V AC three-pole switch, the ABB TC-72367 Spec-Setter heavy-duty fusible switch is rated 600V AC in a NEMA 1 enclosure, and the ABB THN3365A is a 400A, 3-pole, 600V heavy-duty switch for larger feeders. Choose between them based on the ampacity your feeder requires and whether the design wants fuses in the switch.
8) How much wall space do I need for the Eaton DG321UGB 30A disconnect?
The enclosure measures 10.69 by 6.38 by 6.88 inches (height, width, depth) and weighs 6 lb. That footprint drops easily onto a stud or unistrut next to a rooftop or mechanical room unit, and the light weight means no special backing is needed. Leave the NEC working clearance in front of the handle.
9) Is a general duty switch good enough for my application, or do I need heavy duty?
General duty switches like this Eaton 30A are built for light commercial and residential-type loads at 240V or less, in clean indoor locations. Heavy duty is what you specify for industrial plants, higher fault duty, and 600V systems. If your spec calls for heavy duty, look at the Square D VisiPacT unfused NEMA 1 switch or the ABB Spec-Setter heavy duty line instead of this one.
10) Does this switch include a neutral bar for the grounded conductor?
The DG321UGB is a 3-pole, 3-wire switch, so it switches three ungrounded conductors and does not come with a neutral provision. If your circuit carries a neutral, or the switch is being used at the service entrance, you need to add a neutral kit.
11) Is the Eaton DG321UGB certified for installation in Canada?
It is CSA Certified, which is what an inspector looks for on Canadian jobs. Both orderable packs, DG321UGB and DG321UGB-CSA, are the same 30A 3-pole 240V general duty non-fusible switch.
12) Can I use this 30A switch as the disconnect within sight of a rooftop AC unit?
Yes, provided the unit is 240V or less, draws no more than 30A, and the location is indoors or inside a weatherproof enclosure. It is a non-fusible single-throw disconnect, so it satisfies a within-sight disconnecting means but adds no fuse protection. A rooftop in the weather needs a rain-tight enclosure, not this NEMA 1 box.
13) What is the difference between the Eaton DG321UGB and the ABB TG-Series Spec-Setter safety switch?
Both are general duty safety switches. The split is fusing: the Eaton DG321UGB is non-fusible and single-throw, rated 30A, 240V, three-pole, 3-wire, in a NEMA 1 painted steel enclosure, while the ABB TG-Series Spec-Setter is a general duty fusible switch, meaning fuses are carried inside the enclosure. Specify the DG321UGB where overcurrent protection sits upstream and you only need a local disconnecting means, and the TG-Series where the disconnect itself must hold the fuses.
14) Is the ABB THN3365A a substitute for the Eaton DG321UGB 30A disconnect?
No - they serve very different loads. The THN3365A is a 400A, 3-pole, 600V heavy-duty switch sized for large feeders, while the Eaton DG321UGB is a 30A, 240V, three-pole general duty switch in a NEMA 1 painted steel enclosure weighing about 6 lb with a 10.69 in by 6.38 in by 6.88 in footprint. A 400A frame will not fit the same wall space or conduit entries as the 30A unit, and the DG321UGB is not approved for service entrance unless a neutral kit is installed.
