Safety disconnect switch for indoor maintenance

The Eaton DG321UGB is a non-fusible safety switch rated at 30 A and 240 V for three-pole single-throw operation. It provides a visible means to isolate power during equipment servicing or emergency shutdowns in commercial and light-industrial settings.

NEMA 1 enclosure limits outdoor and wet use

The NEMA 1 rating protects against falling dirt in indoor locations but does not guard against water, oil, corrosive agents or external ice formation. Installations exposed to weather, wash-down areas or hazardous atmospheres require a higher-rated enclosure.

30 A 240 V 3PST rating determines circuit fit

The switch carries a maximum of 30 amperes at 240 volts AC across three poles, so it suits loads within that current and voltage envelope. Circuits exceeding 30 A or requiring fused protection need a different device.

Questions about this item

Should I choose the 30 A version for a 240 V circuit?

The DG321UGB is rated 30 A at 240 V, so it matches that circuit directly.

How does the 30 A rating hold up under continuous load?

The 30 A rating is the maximum AC current the switch can interrupt; actual performance varies with load and ambient conditions.

What does the NEMA 1 enclosure limit in practice?

NEMA 1 suits indoor general-duty use, protecting against dust and light water contact but not outdoor or wash-down environments.
