Bussmann Fuse 500A 125VAC/80VDC for Crown – ANN-500

Rated to clear a 500 amp fault at 125VAC and 80VDC, this Bussmann very fast acting current limiter protects the highest-current circuits on an electric lift truck from short circuit and overload. It opens before the heavy wiring, contactors, or motor controllers it guards can sustain damage, interrupting the fault in a fraction of a cycle rather than at the slower response of a time delay fuse.

A fuse this large sits in the main battery or motor power circuit, the heaviest current path on the truck, where an unchecked fault can cause serious damage almost instantly. When the limiter opens, it has already interrupted that fault current fast enough to protect the components downstream, and the circuit stays dead until the fuse is replaced.

Cataloged for Crown equipment, this Bussmann limiter is a direct replacement; match both the 500 amp rating and the 125VAC/80VDC voltage rating to the fuse being replaced, since a limiter that differs in either will not protect the circuit the same way.
