Bussmann Fuse 175A for Crown – ANN-175

A Bussmann ANN-175 very fast acting limiter fuse rated at 175 amps, with the ANN series rated for 125 volts AC and 80 volts DC. It is a bolt-down flat limiter, roughly 3-3/16 inches in body length, made by Bussmann under the Eaton brand and used to protect electrical circuits on lift trucks and similar equipment against overcurrent.

The very fast acting design means it clears a fault quickly, limiting the energy that reaches downstream components, which is why this style is chosen for protecting motors, controllers, and battery circuits. The 175 amp rating is the continuous current it is sized to carry, and the bolt-down flat body mounts directly to bus terminals rather than clipping into a holder. A fuse is a one-time protective device: once it opens on a fault or fatigues from repeated high-current cycling, it is replaced with the same rating. Match the amperage and body style to the fuse being replaced so the circuit protection stays correct.
