The Egis Mobile Electric 3913B is a sealed single Class T fuse block for fuses from 450–600A. Separate stud connections let heavy-gauge cables land on dedicated studs instead of on the fuse tabs, giving a stronger, more reliable joint and making fuse changes easy.
Tin-plated copper busbars keep voltage drop to a minimum, stainless self-locking hardware holds torque, and the glass-filled nylon base with clear break-away cover is sealed to IP66, IP67 and IP6K9K. It is ignition protected for gas boats and LPG installations, and is height compatible with other Egis FLEX system components for busbar linking.
