The fuse and breaker protect your cabling from overheating (and potentially catching fire) and protect your equipment. This 125 Amp Bussman Fuse with mounting bracket mounts to the positive battery post, and the positive cable hooks to the top of the fuse, then runs directly to the power inverter.
Use this fuse with 1000 Watt power inverters. A fuse between the battery and power inverter is highly recommended for safety and protection of the equipment. The correct cable size is also important. Your power inverter’s User Manual should provide the recommended cable size.
75 Amp Bussman Fuse also available.
