The Egis Mobile Electric 3493B MT Series is a sealed, connectorized marine fuse and circuit breaker block – an industry first. Instead of screw terminals, each output exits through integrated Deutsch™ / Amphenol™ power connectors, eliminating the assembly errors and corrosion failures common with traditional screw terminations during and after build. Its inputs are split into a 9-circuit group and a 3-circuit group, so two separate sources (for example, house and start, or switched and unswitched) can share one block.
It accepts ATM fuses or ATM Type III circuit breakers up to 30A while the sealing cover stays on, and carries a 250A integrated ground return bus under the cover. Sealed to IP66 / IP6K9K and ignition protected to SAE J1171, it links to Egis XD relays and high-amp fuse blocks with standard FLEX busbars.
Key Features:
- 12 ATM fuse / ATM Type III circuit breaker positions, up to 30A each
