Egis 3911 Class T Fuse Block 110-200A, 80V Marine
Egis 3911 Class T Fuse Block 110-200A, 80V Marine — Product description
The Egis 3911 is a sealed, ignition-protected fuse block built to hold a Class T fuse rated 110 to 200 amps. Tin-plated copper busbar, glass-filled nylon housing, and stainless hardware make it a solid choice for high-current DC circuits on inverters, windlasses, and main battery feeds.
The Egis Class T Fuse Block gives you a sealed, ignition-protected home for a Class T fuse rated from 110 to 200 amps. It's built for the high-current DC circuits you find on inverters, windlasses, and main battery feeds, where a Class T fuse is the right call for its high interrupt rating.
What makes this one worth it? The busbar is tin-plated copper, so you get minimal voltage drop and clean current flow even under load. The housing is glass-filled nylon, which shrugs off heat, vibration, and the damp. Stainless steel self-locking hardware keeps your connections tight over the long haul, and separate stud connections let heavier-gauge cables land on their own studs instead of crowding the fuse tab.
It's ignition protected and rated IP66, IP67, and IP6K9K, so you can mount it in an engine bay or near LPG without worry. Max voltage is 80 Vdc. Four #10 (M5) and two 1/4-inch (M6) mounting holes anchor it down, and you torque the screws to 50 in-lbs. The Class T fuse itself is sold separately, so match it to your circuit. Backed by a 4-year warranty.
