Easy Installation Compact Heavy Duty Vehicle Ship Ignition Protected MRBF Marine Rated Battery Fuse 58V 300A

Easy Installation Compact Heavy Duty Vehicle Ship Ignition Protected MRBF Marine Rated Battery Fuse 58V 300A

The MRBF Fuse provides easy, weatherproof and economical circuit protection in tight space constraints. The fuse is installed between the positive battery terminal stud and the positive battery cable with the help of a special clamping fixture. Marine Rated Battery Fuses are a practical and economical method for safe operation of your power inverter.

A battery is an unlimited source of current. If there is a short circuit along the length of the cables that connect the battery to the inverter, thousands of amperes of current can flow from the battery causing shorting: a section of the cable can overheat, the insulation can melt and the cable can ultimately break. This interruption of high current can generate hazardous, high temperature, high energy arc accompanied by a high pressure wave that may cause fire, damage to nearby objects or injury. To prevent the occurrence of such hazards under short circuit conditions, an appropriate fuse should be used in the battery circuit with the required current interrupting capacity (Termed AIC – Ampere interrupting Capacity).

Designed for the most demanding environment to provide high current protection for the tightest space constraints. Suitable for main and auxiliary circuit protection such as alternator outputs, starter motor inputs, and accessory circuits. The breaking capacity meets the requirements of conventional vehicle batteries and 12V, 24V and 42V electrical networks.
