B-LINE DH322FDK – Frequently Asked Questions
1) Will the Eaton DH322FDK 60A safety switch work on a 480V system?
No. The DH322FDK is rated 240V maximum, so it's only suitable for 120/240V single-phase or 240V three-phase circuits. For 480V service you need a 600V-rated heavy duty switch instead.
2) Does the DH322FDK come with fuses, and what fuse class does it take?
Fuse clips in the DH322FDK are set up for Class H fuses at 60A, three-pole. Fuses are a separate order, and the switch is the fusible-without-neutral configuration, so there is no neutral assembly in it either.
3) Can I use this 60A Eaton disconnect as a service entrance disconnect?
Yes, but only once you add hardware. The DH322FDK is suitable for service entrance use with a neutral or ground lug kit installed. It ships as a three-pole, three-wire fusible switch without neutral, so the lug kit is a separate line item on the order.
4) Is the DH322FDK safety switch rated for outdoor mounting?
The enclosure is NEMA 12/3R in painted galvanized steel. To get the 3R rainproof performance outdoors, you open the factory provided drain hole in the bottom of the can, which is a field modification described by Eaton. Left unopened, it serves as an indoor NEMA 12 dusttight, driptight enclosure.
5) What size motor can I run through a DH322FDK disconnect?
Max horsepower on the DH322FDK is 3 hp single-phase and 7.5 hp three-phase with standard fuses, 10 hp and 15 hp respectively with time delay fuses, and 10 hp on 250 Vdc. Fuse type you pick changes the hp you get, so specify time delay if you are near the top of that range.
6) What wire size will the lugs on this Eaton 60A switch accept?
Line and load terminals take #14 through #2 AWG, copper or aluminum. That covers the usual 60A copper and aluminum feeder sizes without a reducing lug.
7) How much wall space do I need for the DH322FDK, and how heavy is it?
Plan on an enclosure measuring 20 x 9.5 x 8.5 inches and 22 pounds. At that weight, mount it to studs or use anchors rated accordingly, and leave working clearance in front per your local code.
8) Should I pick a fusible safety switch or a non-fused disconnect for my rooftop unit?
A fusible switch like the DH322FDK gives you both the local disconnecting means and overcurrent protection in one enclosure, which is what you want when the equipment nameplate calls for fuse protection or the branch circuit isn't already protected at the right size. A non-fused disconnect only breaks the circuit and relies on upstream protection. Note this one is fusible without neutral, so a neutral or ground lug kit is needed if you're landing a neutral.
9) Is the DH322FDK a three-phase disconnect or can it be used single-phase?
It's a three-pole, three-wire switch, so it's built for 240V three-phase, and you can also use it single-phase by landing on two of the three poles. Horsepower ratings are published for both: 3 hp at single-phase and 7.5 hp at three-phase with standard fuses.
