Del City's Micro3 sub-miniature fuse and MCase Cartridge Fuse are designed for use in newer vehicles and take advantage of smaller dimensions in order to fit more fuses into tight spaces.

The Micro3 is available in 5, 7.5, 10 and 15 amp versions.

The MCase Cartridge is a cartridge-style fuse with female terminals for 2.8-millimeter male terminals. It is a time-delayed fuse that can handle in-rush currents with an interrupting rating of 1,000 amps at 32 volts DC. It comes in 15-, 20-, 25-, 30- or 40-amp fuses.

Del City also carries Maxi Fuses, ATC/ATO fuses and the Micro2 sub-miniature fuse. Del City is a direct supplier of electrical and transportation supplies including wire, fuses, terminals and switches.
