A modular DC bus bar, with locations for four DC fuses. It will monitor the status of each fuse, and indicate its condition with a LED on the front. Part of the modular Lynx distribution system.
This unit is an alternative to using separate positive and negative bus bars for your 12 volt DC distribution and also integrates fusing. By combining both of these functions you simplify your electrical system wiring for about the same cost as buying all the bus bars and fuses/circuit breakers.
