High Current Fuses protect against overcurrent of heavy-gauge cables. These fuses bolt onto Mega Fuse Holders for a consistent connection to the circuit with a secure hold that resists movement from vibrations. This fuse has a rating of 60 Amps and 32 Volts. Fuses are a necessary component in an electrical circuit because they offer an essential protection by acting as the weakest point in a circuit. When a current is too strong, the fused element inside a fuse will heat up and break so that the current can no longer complete the circuit.
