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.
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).
Our MRBF
fuses are available in 100 amps, 200 amps and 300 amps.
Features:
- Clamping Fixture Bar (CFBAR) has a base plate for connecting to the battery stud (with a hole
to accommodate battery stud of up to stud size 3/8" / M10) and a stud (size M-8) for connecting the
fuse MRBF and the battery cable.
- Stainless Steel nut (thread size M8, will require ½" or 13 mm wrench for tightening), Flat Washer and
Spring Washer
- An Insulating Cap slides over the base plate of CFBAR and is used to insulate the exposed
stud and the nut of the CFBARs
