DESCRIPTION
New open box Bussmann LPJ-2-1/4SP Low-Peak dual-element time-delay Class J fuse, rated 2-1/4 A at 600 VAC with a 300 kA interrupting rating, and 300 VDC with a 100 kA interrupting rating. The label reads "Cooper Bussmann Low-Peak Ultimate Protection, Dual-Element Time-Delay Class J Fuse, LPJ-2-1-4SP," with UL Listed, CSA Type D, CE and UKCA marks and "Eaton, St. Louis, MO 63178, Assembled in Mexico." The fuse has not been installed. The label is readable with light handling marks. The copper end caps show tarnish from storage, as pictured.

The LPJ-SP is Bussmann's Low-Peak Class J time-delay fuse. It holds 500% of its rating for at least 10 seconds, so control transformer inrush and small-motor starting current pass without nuisance opening. Its current-limiting design gives a high level of protection. The 2-1/4 A rating is a common size for control power transformer primaries and small motor and control circuits. The Class J dimensions reject other fuse classes, so the wrong fuse can't be installed.
