Egis Mobile Electric 3911 Class T Fuse Block 110-200A Sealed

The Egis Mobile Electric 3911 is a sealed Class T fuse block designed for high-current DC electrical systems in marine, RV, automotive, and powersports applications. Rated for fuses from 110 to 200 amps at up to 80 volts DC, it provides robust overcurrent protection for inverters, battery banks, and other high-draw electronics. The fully sealed, IP66/IP67/IP6K9K-rated enclosure makes it suitable for use in wet, dusty, and chemically challenging environments.

Key Features:

• Ignition protected — safe for installation in potentially hazardous gaseous environments, including LPG-equipped vessels and gasoline-powered boats
• Fully sealed to IP66, IP67, and IP6K9K — provides protection against water ingress, dust, and chemicals
• Separate stud connections for cable mounting — allows heavier gauge cables and ring terminals to connect directly to the block, bypassing the fuse tab and accommodating larger wire gauges
• Tin-plated copper busbars — deliver superior electrical conductivity with minimal voltage drop
• Stainless steel self-locking hardware — ensures robust, long-lasting connections that resist vibration and corrosion
• Glass-filled nylon housing — provides bulletproof durability in demanding environments
• Includes protective transparent cover with break-away tabs for easy cable access and visual fuse inspection without full disassembly
• Height compatible with Egis Flex System components — integrates seamlessly into modular electrical panel builds
• Mounting holes: 4x #10 (M5) and 2x 1/4" (M6)
• Mounting screw max torque: 50 in-lbs (5.5 N-m)
• 4-year manufacturer warranty
