Fusible AC Disconnect Switch 240V 30A

The GE fusible disconnect switch is a three-phase pull-out unit rated for 240V AC and 30 amps. It uses Class H fuses for overcurrent protection in a galvanised steel NEMA 3R enclosure rated IP14. The switch is cUL and UL listed for outdoor air-conditioning circuits.

Installers wiring residential

This switch suits electricians fitting a 7 1/2 hp motor load on a 240V three-phase supply where local code requires a fusible disconnect. It will not suit single-phase equipment, loads above 30 amps, or installations that demand a non-fusible or higher IP-rated enclosure.

30 ampere current rating

The 30 A rating is the decisive figure: the switch must match the circuit breaker and conductor ampacity for the connected motor. Exceeding this value requires a different disconnect; a lower load can use this switch provided the fuses are sized correctly.

Questions about this item

What mounting depth does the galvanised-steel enclosure need?

The enclosure is 5 1/4 in deep, so allow at least that much clearance behind the mounting surface for the pull-out mechanism and wiring.

How do I install the pull-out fuse holder without damaging the contacts?

Align the pull-out block with the guide rails, push straight in until it seats firmly, then snap the handle down; forcing it at an angle bends the blade contacts.

Which fuse class and amperage must I keep on hand for replacement?

Use Class H fuses rated 30 A at 240 V AC; the disconnect is fusible-protected and cUL/UL listed for that exact class and rating.
