Bussmann SSU Box Cover Unit, Single Receptacle Fuse Holder with Switch

The Bussmann SSU Box Cover Unit is a single-receptacle fuse holder with switch control, engineered to accept plug fuses in a compact handy box configuration. Rated 15A at 125V, this box cover unit measures 4.44 IN long, 2.78 IN wide, and 2.03 IN high, weighing just .39 LB, making it a straightforward retrofit for standard handy boxes that need switched, fused receptacle protection. The single-receptacle design pairs a plug fuse holder with an integral switch, so a technician can de-energize the circuit at the fuse location before servicing, replacing the fuse, or resetting the connected load without having to trace the circuit back to a distribution panel.

  • Compact Dimensions: 4.44 IN long x 2.78 IN wide x 2.03 IN high, weighing only .39 LB for easy handling, shipping, and installation in tight electrical enclosures.

Bussmann SSU – Frequently Asked Questions

1) Will the Bussmann SSU box cover unit fit a standard handy box?
Yes. The SSU is a handy box cover unit, so it mounts directly to a standard handy (utility) box in place of a blank or duplex cover. Overall it runs 4.44 in long, 2.78 in wide and 2.03 in high, so allow for that 2.03 in depth clearance above the box face where the fuse holder and switch body project.
2) What kind of fuse does the Bussmann SSU box cover unit take?
Plug fuses, the screw-in Edison-base type. It is not built for cartridge fuses. Rating is 15A at 125V, so size the plug fuse to the circuit and conductor, up to that 15A ceiling.
3) Can I use this fused receptacle unit on a 240V circuit?
No. The SSU is rated 125V, which makes it a single-pole, 120V-class device only. A 240V load needs a two-pole fused disconnect rated for that voltage, not this cover unit.
4) I'm replacing an old plug fuse holder on a machine or appliance circuit. Is the SSU a direct retrofit?
It is built for exactly that job. The SSU is intended for handy box retrofits needing switched fuse protection and for replacing legacy plug fuse holders on single-circuit installs. Confirm your existing box is a standard handy box and that the load draws 15A or less at 125V.
5) Does the Bussmann SSU give me a local disconnect so I don't have to shut off the panel?
That is the point of the switch. The SSU pairs the plug fuse holder with an integral switch, so a tech can kill the circuit right at the fuse to change the fuse or service the connected load, without tracing back to the distribution panel or disturbing upstream wiring.
6) Is this a single or duplex receptacle?
Single. The SSU carries one fused receptacle, not a duplex pair, so it is meant for one dedicated load per box. If you need two outlets at that location you are looking at the wrong device.
7) Does the Bussmann SSU come with a fuse in it?
The SSU is the box cover unit itself, an Edison-base plug fuse holder with switch. Order the plug fuse separately and match its rating to the branch circuit, not exceeding the unit's 15A rating.
