Eaton DH Series Heavy-Duty Fused Safety Switch, 3-Pole, NEMA 1

The Eaton DH Series heavy-duty fused safety switch family, including the DH323FGK and DH366FGK models, delivers a rugged, enhanced visible blade single-throw disconnect for manual overcurrent protection in industrial and commercial power distribution systems. Housed in a painted steel, NEMA 1 enclosure for indoor use, these three-pole, three-wire switches are fusible without neutral and accept Class H fuses for coordinated circuit protection; ratings vary by model, with the DH323FGK rated 100A at 240V and offering maximum horsepower ratings of 7.5, 15/15, and 30/20 Hp. As part of Eaton's heavy-duty safety switch line, this family is well suited for panelboards, motor control centers, and equipment rooms where a visible, lockable disconnect is required.

Key Features

  • Enhanced Visible Blade: Single-throw visible blade mechanism lets technicians confirm open/closed disconnect status at a glance.
  • Durable Construction: Painted steel enclosure resists wear and supports long-term indoor service across the DH Series family.
  • NEMA 1 Enclosure: General-purpose indoor enclosure rating shared by both the DH323FGK and DH366FGK models.
  • Fusible Design: Fusible without neutral configuration accepts Class H fuses for coordinated overcurrent protection.
  • Three-Pole, Three-Wire: Configuration rated for reliable branch-circuit and motor disconnect service.
  • Manual Disconnect Operation: Single-throw switch mechanism provides straightforward on/off control for maintenance and lockout/tagout procedures.
  • Model-Specific Ratings: The DH323FGK is rated 100A at 240V with maximum horsepower ratings of 7.5, 15/15, and 30/20 Hp; consult Eaton documentation for DH366FGK ratings.

Eaton DH323FGK – Frequently Asked Questions

1) What amperage sizes does the Eaton DH Series fused safety switch come in?
Two: the DH323FGK at 100A and the DH366FGK at 600A. Both are three-pole, three-wire fusible switches without a neutral. The 100A DH323FGK is rated 240V; pick the 600A DH366FGK where the feeder or motor load needs the larger frame.
2) What fuse class do I need to order for an Eaton DH fusible disconnect?
Fuses are not supplied with the switch, and the DH fusible design accepts Class H fuses. Size them to the branch circuit or motor load you are protecting. The switch itself is fusible without neutral, so there is no neutral kit in the box either if your circuit needs one.
3) Will this Eaton DH switch work as a motor disconnect, and what horsepower will it carry?
Yes, it is intended for industrial motor disconnect duty. The 100A DH323FGK carries maximum horsepower ratings of 7.5, 15/15 and 30/20 Hp. The visible blade mechanism lets an electrician confirm the blades are open before working on the motor, which is what makes it usable for lockout/tagout.
4) Is the Eaton DH323FGK rated for a 480V or 600V system?
The DH323FGK is rated 100A at 240V, so it is not the part for a 480V or 600V feeder. For 600V class work, look at a 600V heavy-duty switch such as the ABB TC-72367 Spec-Setter 3-pole 600V AC NEMA 1 or the ABB THN3365A 400A 3-pole 600V unit.
5) What should I use instead of the Eaton DH Series NEMA 1 safety switch for a wet or washdown outdoor location?
The NEMA 1 painted steel enclosure on the Eaton DH Series is a general-purpose indoor rating. For a washdown or corrosive location, the Square D VisiPacT VH324NDSGL is a heavy duty fused safety switch in a NEMA 4X stainless steel enclosure, which is the rating and material suited to hosedown and corrosion exposure. Both are fused heavy duty switches, so the protection scheme carries over.
6) Does the Square D VHU361N work as a substitute for an Eaton DH366FGK?
Not directly. The Square D VHU361N is a heavy duty unfused safety switch in a NEMA 1 enclosure, while the Eaton DH366FGK is part of the DH Series fusible line that accepts Class H fuses for overcurrent protection. The enclosure rating matches, but an unfused switch provides disconnect only. Use the VHU361N when overcurrent protection is handled upstream and you only need a lockable disconnecting means.
7) What is the closest cross-brand equivalent to the Eaton DH323FGK fused safety switch?
The ABB TC-72367 Spec-Setter is the nearest match in another brand: it is a heavy-duty fusible safety switch, 3-pole, with a NEMA 1 enclosure, the same basic configuration as the Eaton DH Series switch, which is a 3-pole heavy duty fusible safety switch in a NEMA 1 painted steel enclosure. The ABB unit is rated 600V AC, so confirm your system voltage against the Eaton rating of 240V for the 100A DH323FGK before swapping.
8) I need a 400A 600V heavy-duty disconnect and the Eaton DH switches are 100A and 600A. What else fits?
The ABB THN3365A is a 400A, 3-pole, 600V heavy-duty safety switch, which lands between the two Eaton DH Series amperages of 100A and 600A. All three are 3-pole heavy-duty disconnects; note that the Eaton DH Series switches here are fusible units accepting Class H fuses, so verify the fusing arrangement matches your protection scheme.
9) What is the difference between a heavy-duty and a general duty fusible safety switch?
Heavy duty switches like the Eaton DH Series are built for industrial service, with a painted steel enclosure and a visible blade single-throw mechanism for motor control centers, panelboards, and equipment rooms. A general duty unit, such as the ABB TG-Series Spec-Setter fusible switch, is the lighter-service alternative for residential and light commercial loads. If the disconnect is feeding a motor or sits in an industrial room, stay with the heavy duty frame.
10) Can I use this three-pole Eaton switch on a circuit that needs a neutral?
Not as supplied. The DH Series switch here is a three-pole, three-wire fusible unit without neutral, so there is no neutral landing provided. If your circuit carries a neutral through the disconnect, specify a switch with a factory neutral assembly.
11) How does a maintenance tech verify this disconnect is actually open?
The DH Series uses an enhanced visible blade, single-throw mechanism, so the open or closed position of the blades can be confirmed by eye rather than trusting the handle alone. That, plus a lockable handle position, is why these get specified for facility lockout/tagout points.
