The Egis Mobile Electric 3912 is a sealed Class T fuse block rated for 225–400 amps, engineered for high-current DC electrical systems in marine, RV, and powersports applications. Separate stud connections for cable mounting allow heavier gauge cables and their terminals to feed in and out of the fuse independently, rather than terminating directly on the fuse tab itself — enabling cleaner, more reliable high-amperage wiring.
Built for the harshest environments, the 3912 carries a triple ingress protection rating of IP66, IP67, and IP6K9K, providing comprehensive defense against water, dust, and chemicals. It is also fully ignition protected, making it safe for installation in potentially hazardous gaseous environments including LPG and gasoline-powered vessels.
