Cooper Bussmann offers a heavy duty modular fuse panel called the LMI “Little Block”. The LMI is connected with a large fused main battery connection branch with primary fuse or circuit breaker at the battery end (sold separately) feeding the input module and branches out via the busbar to accept two up to six individual outgoing industry standard Midi/AMI fuses.

On our webstore you can buy all of these componants individually as follows:

  • LMI Input Module
  • LMI Midi Fuse Holder
  • Busbar - available in 3 hole to 7 hole configuration depending on the number of fuse holders you need
  • Midi fuses for each outgoing circuit

The Input Module has 1 x large 5/16 (M8) single stud with nut for the incoming cable connection from the battery. You then add as many Fuse holders as required (2-6) with the input module and busbar to connect them. These fuse holders clip together to make a modular busbar arrangement.  Best practice is to install the input module in the centre of the block with the highest current output circuits closest to the input module.

Fuse holders have 2 x 3/16" (M5) studs with nuts.  You will need cable lugs with 5 or 6mm hole size max.  These are ideal for inline fuse protection for a single circuit or for a multi circuit fuse block/busbar set up with the following components:
• 1 x Input Module (single bolt input)
• 2 to 6 outgoing Fuse holder circuits connected to the input module by busbar
• 1 x busbar (1 hole for input module and 1 hole per fuse holder)
• 2 to 6 midi fuses

If you don't want the input module and busbar setup and just want multiple separate fuse holders, then you can purchase individual fuse holders seperately.

These can be used for any DC circuit protection up to a total busbar current of up to 400 amps and max of 200 amps per fuse holder. They will take any standard midi/AMI fuse and can be used for (but not limited to) the following applications:

  • Dual battery installations
  • Inverter cabling
  • DCDC charger
  • Solar installations
  • Marine power supplies

Midi fuses are available in 30, 40, 50, 60, 70, 80, 100, 125, 175 and 200A sizes which you can find here

The LMI provides efficient power distribution suitable for many applications such as:

  • 4WD/Caravan
  • Marine
  • Construction
  • Agriculture
  • Heavy Trucking
  • Bus
  • Specialty Vehicles
