12 way, standard blade fuse holder with a protective cover. Comprises 2 independent positive busbars (e.g. for 1 permanent live busbar and 1 ignition-switched busbar) and 1 negative busbar:

  • Positive busbar A - 1 x common busbar and  6 x individual circuits protected by standard blade fuses
  • Positive busbar B - 1 x common busbar and  6 x individual circuits protected by standard blade fuses
  • Negative busbar -  1 x common busbar and 12 x individual connection blocks
The multi-connection negative circuit is particularly useful for marine applications where the ground returns from each circuit need to be 'commoned' for connection back to the battery -ve. Also useful in non-marine applications to bring all ground connections together, so if you suspect a bad earth all your terminals are in one place, making fault finding much easier.

All common buses have an M5 stud and nut terminal for connection. All other connections are via M4 screw terminals.

The cover is secured via a sprung rotary locking mechanism and incorporates two slots for storing spare fuses and moulded-in recesses to affix labels for easy circuit identification. The base contains 4 fixing holes for mounting the fuse box to a flat surface.

Accepts our range of standard blade fuses (including LED glow versions).

Sold individually (fuses and terminals not included).

Nice compact fuse box
Monday, 17 December 2018  |  John

Re-wired a T5 Camper yesterday and used this as the main fuse box to organise LED lighting, diesel heater, socket outlets, USB outlets and fridge. Easy to fit under the driver's seat and the two busbars made for a neat and structured install.

Excellent product

Installed a 12V PV and USB/12v socket system and this made it so easy to do a professional job - we'll worth it!

Just what I needed!

I have a big habit of putting gadgets in my Car I love gadgets! And with this it helps my battery not looking like a spaghetti junction and I dont have to undo the battery connectors to add more stuff only this junction box which I've hid inside the car. Found something similar like this before but not as good and with only the positive pole on it. This has both and although the price curled my eyes abit I dont regret buying it!!
