Our Hi-Amp style circuit breakers are the ultimate protection for dual battery systems or high DC current electrical circuits. These 100A rated units have an IP67 rating, which means they are sealed internally against moisture, dust and dirt and ignition protected. This makes them ideal for under bonnet applications where the vehicle is used for serious off road work. Other applications also include heavy industrial, agricultural and marine. Featuring trip indicator and manual trip button, these circuit breakers are easy to reset just by pushing the tab back in. They are well built with a sturdy surface mounting frame. Connection is via two 3/4 stainless steel studs, which ensure a rock solid termination point for your cables.
