Bussmann LP-CC-4 – Frequently Asked Questions
1) Will a Bussmann LP-CC-4 fit my existing Class CC fuse holder?
Yes, if the holder is a Class CC rejection-style holder. The LP-CC-4 is a Class CC ferrule-end fuse measuring 1.5 inches long by .41 inch diameter, which is the standard 13/32 x 1-1/2 inch Class CC envelope, and it uses rejection-style construction so it will not seat in a holder built for a non-rejection midget fuse. Both ends are ferrule, so the block must be a ferrule clip type rather than a bolt-in.
2) Can I use a 4A LP-CC fuse on a 480V or 600V control transformer primary?
The LP-CC-4 is rated 600 Vac, so it covers 480V and 600V primary circuits as well as anything below. On DC it is rated 150 Vdc. Interrupting capacity is 200 kAIC at 600 Vac and 20 kAIC at 150 Vdc, which covers the available fault current on most industrial services. It is a dual-element time-delay fuse, so it rides through the inrush a control transformer draws on energizing instead of opening on it.
3) Will a 4A LP-CC hold on motor starting inrush, or should I use a fast-acting fuse?
It holds. The LP-CC-4 is a dual-element time-delay design that carries 200 percent of rating for 12 seconds before opening, which is what lets it sit through motor starting current and short-term overloads while still clearing a short circuit fast. A fast-acting Class CC fuse of the same 4A rating would nuisance-open on that same inrush. Use fast-acting only where the load has no inrush, such as straight resistive or some electronic supplies.
4) Does the LP-CC-4 have a blown fuse indicator I can see in the panel?
No. The LP-CC-4 is a non-indicating fuse, so there is no pop-up pin or window to tell you it has opened. In a control cabinet you will need to check it with a meter or use a fuse holder with its own blown-fuse indication. If a technician needs visual status at the door, plan on an indicating holder rather than expecting it from the fuse.
5) What does current-limiting actually get me in a control panel?
A current-limiting fuse opens within the first quarter cycle of a high fault and cuts off the peak before it develops, so the let-through energy reaching downstream contactors, relays and electronics is far lower than a non-current-limiting device would pass. On the LP-CC-4 that is paired with a 200 kAIC rating at 600 Vac, which is what allows it to be applied on services with high available fault current and supports series and selective coordination work.
6) How do Bussmann LP-CC fuses ship, and can I buy a single one?
LP-CC-4 fuses are packed in standard cartons of 10. That is the usual buy for anyone stocking a control panel spares kit, where you want matched fuses on the shelf for every 4A circuit in the cabinet.
7) Is the LP-CC-4 body suitable for a hot industrial enclosure?
The fuse body is a melamine tube, which is the standard thermoset barrel used on Class CC fuses for control panel duty and handles the heat inside a loaded cabinet. The whole fuse weighs .15 lb.
8) Does the LP-CC-4 carry any certification marking for an export or international panel build?
It is CE marked, so it can go into equipment built to European marking requirements. Class CC construction also means it meets the dimensional and current-limiting requirements that define that fuse class.
