What are MIDI fuses?

MIDI® Fuses are a cost-effect, space saving protection solution for high current wiring. MIDI® Fuses are common standard circuit protection devices for automobiles and trucks. Tin plated contacts on the MIDI® Fuses provide excellent corrosion resistance to keep the fuse protected and performing.

What are the dimensions of a MICRO2 fuse?

Micro2 – Also known as APT or ATR, these fuses have ratings from 5 up to 30 amp. Measurements are 9.1l × 3.8w × 15.3h mm Micro3 – Also known as ATL, these 14.4 × 4.2 × 18.1 mm fuses run from 5 to 15 amp LP-Mini/APS/ATT – Fuses measure 10.9 × 3.81 × 8.73 mm, and are rated from 2 to 30 amp.

What kind of Fuse is used for a starter?

MRBF/ZCASE – This is a single MEGA type fuse that is used for very high current application, most commonly the starter. It is mounted with a single bolt. Fuse ratings range from 40 to 250 amp. Class-T – commonly used for EV and hybrid vehicles, the class-T fuse is a high voltage fuse.

What are the dimensions of slow blow fuses?

These slow blow fuses measure 10mmx 41mm. ANL – These fuses measure 20 x 82 mm and cover a range from 20 to 500 amp. Unlike the other bolt-down fuses, this design has slotted ends, so the bolts do not have to come out completely. ANL fuses are also used for high-current applications, and can go up to 500 amps.

What kind of Fuse is used on AGU battery?

This AGU fuse is a 40 amp, notes on the side. The high-amp glass fuses can melt the solder before the actual fuse pops. Bosch – Used in older European vehicles, these plastic barrel fuses have exposed metal fuse link. They install similar to a AA-type battery between two flat springs.
