It is a fast-acting fuse, typically color-coded tan, and rated for 32 volts DC. When the current exceeds 70 amps, the fuse element melts to prevent damage to wiring and connected components. These fuses are commonly found in fuse blocks for fans, ABS systems, and power distribution modules, and should be replaced with a same‑rating 70A Maxi fuse if blown.
