Description
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.
• Heavy-Duty/Medium-DutyTrucks
• Truck Upfitters
Features and Benefits
• 5-way fuse holder accepts 2 MEGA® and 3 MIDI®
bolt-down fuses rated between 30A and 500A (fuses
sold separately)
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.
• 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)
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.
• 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
