For high-powered commercial vehicle applications, where individual fuse holders may be inefficient or leave the fuse connections exposed to the elements, a sealed, multi-fuse holder like the MDB5 Series MEGA® & MIDI® Fuse Power Distribution Box may be a better, more cost-effective choice.

This 5-way power distribution box is designed with a sealed enclosure that protects the fuse connections from the corrosive conditions typically found in the battery box or under the hood. In addition, cable seals or plugs can be added to achieve IP67 and IP69K ratings, ultimately turning the fuse holder into a dust-tight and waterproof fuse box for use in the harshest environments.

With dual, configurable inputs, the MDB5 Series power distribution box enables flexibility between high- and low-current applications and up to 400A continuous current. To meet the requirements of both standard voltage vehicles and 48V+ applications, the MDB5 Series is available in configurations that accept 32V or 70V MEGA® and MIDI® bolt-down fuses.

Features and Benefits

  • 5-way fuse holder accepts 2 MEGA® and 3 MIDI® bolt-down fuses rated between 30A and 500A (fuses sold separately)
  • Dual, configurable inputs allow for up to 400A continuous current and for flexibility between high- and low-current applications
  • Models are available for both standard voltage (32V fuses) and 48V+ applications (70V fuses)
  • Sealed enclosure protects all of the fuse connections, enabling circuit protection installation in corrosive environments, such as the battery box or under the hood
  • IP67/IP69K waterproof, dust-tight rating can be achieved with the use of cable seals or plugs
  • Poke-Yoke mounting pattern for easy assembly

Applications
