Bussmann KLM-30 – Frequently Asked Questions

1) Will a Bussmann KLM-30 fuse fit a standard midget fuse holder?
Yes. The KLM-30 is a midget-format fuse with ferrule end x ferrule end termination, so it drops into standard midget-style fuse blocks and holders. If your holder is a class CC type with a rejection feature, a KLM will not seat in it, because midget fuses have plain ferrules without the CC rejection collar.
2) Can I use the KLM-30 on a DC circuit, not just AC?
Both. The KLM-30 carries a 600 Vac and 600 Vdc rating, with an interrupting rating of 100 kAIC at 600 Vac and 50 kAIC at 600 Vdc. That dual rating is why it gets specified on DC bus and battery-side circuits as well as AC control panels.
3) Is a fast-acting KLM-30 the right choice for a motor circuit, or do I need a time-delay fuse?
The KLM-30 is a fast-acting, non-indicating fuse. It clears quickly on overcurrent, which suits semiconductor, control, and resistive loads and branch circuits where inrush is minimal. A motor with locked-rotor inrush will likely nuisance-open a fast-acting fuse at the same amp rating, so for motor starting duty you want a time-delay midget instead of the KLM.
4) What amperage and voltage is the Bussmann KLM-30 rated for?
30 amps at 600 Vac and 600 Vdc. The amp rating is the number at the end of the part number, so KLM-30 is the 30A member of the KLM series. Order by the full MPN KLM-30 to get that rating.
5) Will the KLM-30 hold up in a high fault-current service or a damp panel?
Its interrupting rating is 100 kAIC at 600 Vac and 50 kAIC at 600 Vdc, which covers available fault current on most industrial services where the panel short-circuit current rating is the limiting factor. The body is a melamine tube with nickel-plated bronze ferrules, so the end caps resist corrosion in humid or industrial environments.
6) I need to standardize fuses across control panels in several buildings. Where does the KLM series fit?
The KLM is a 600 Vac/600 Vdc fast-acting midget, so one fuse type covers both AC control circuits and DC circuits in the same panel, which cuts the number of part numbers an MRO stockroom has to carry. Because the amp rating is carried in the suffix, you can stock a range of KLM ratings that all share the same body style and the same midget holders. Confirm each circuit's required amp rating before swapping, since a fast-acting fuse is not a drop-in for a time-delay application.
7) Does the KLM-30 have a blown-fuse indicator?
No. The KLM-30 is non-indicating, so there is no pop-out pin or visual flag to show it has opened. On a panel where techs need to spot an open fuse at a glance, you either need an indicating fuse type or a holder with an open-fuse indicator light.
