Littelfuse LSRY – Frequently Asked Questions

1) Will the Littelfuse LSRY box cover fuse holder work on a 120V residential branch circuit?
Yes. The LSRY is rated 125VAC, which covers standard 120V residential and light commercial branch circuits, and it is sized at 15A for lighting and general-purpose circuits. Running it on anything above 125V or on a circuit needing more than 15A is outside its rating.
2) What kind of fuse goes in a Littelfuse LSRY box cover unit?
It takes standard plug-style fuses, the screw-in type used in older fuse panels. The holder itself is the mounting hardware; the plug fuse is a separate item you size to the circuit, up to the unit's 15A rating.
3) How does the LSRY mount, and do I have to rewire the panel?
It is a box cover mount unit, so it fastens directly onto a compatible fuse panel enclosure cover rather than being panel-interior hardware. That mounting method is what makes it a straight replacement path on existing plug-fuse installations without extensive rewiring.
4) Can I use a box cover plug fuse unit to replace missing fuse holder hardware on an old panel instead of changing the whole panel?
That is the main use case for the LSRY. It restores correctly rated overcurrent protection where the original plug fuse holder hardware has failed or gone missing, keeping the existing panel in service rather than forcing a full changeout. It only applies where the circuit is 125VAC or less and 15A, and where the panel accepts a box cover mounted plug fuse unit.
5) Does the Littelfuse LSRY have a blown-fuse indicator window?
No. The LSRY is a non-indicating unit, so there is no visual window telling you the fuse has opened. Maintenance staff have to pull or test the plug fuse to confirm it blew. If you want an at-a-glance indication on a legacy panel, you need an indicating-type holder instead.
6) Is a 15A plug fuse holder enough for an appliance or motor circuit?
Not likely. The LSRY is rated 15A at 125VAC, which suits lighting and general-purpose branch circuits. Appliance, air conditioning, and motor loads typically sit on higher-amperage or 240V circuits, and those need a holder rated for that circuit, not this one.
