HPDM SERIES POWER DISTRIBUTION MODULE
600 A • MEGA
®
Fuse • 2 Pole • Sealed • AssureLatch™
Description
The 2-Pole High Power Distribution Module (HPDM) is
designed for OEM and aftermarket applications in the
heavy truck and trailer industry. When connected to a
tractor / trailer’s electrical system it provides two high
current MEGA
®
fuse protected circuit outputs as well as
an un-fused output that can optionally be used to parallel
multiple modules or deliver power to circuits which do not
require circuit protection.

Features and Benefits
• Separate fuse compartment provides a seal that protects
the fuses and their terminations from harsh environments.
This allows for permanent cable connections that can be
dielectrically sprayed without affecting the fuse.
• Custom insert-molded studs for input/output cable
terminations and MEGA
®
fuse attachment, resulting in high
terminal torque capability and lower connection resistance.
• Designed to minimize bridging corrosion between positive
live metal surfaces and potentially grounded assembly
hardware or mounting surfaces.
• Metal inserts at the mounting holes allows for an increased
assembly torque without distorting the base material.
• Optional un-fused terminal for daisy chaining multiple
devices or providing power distribution to circuits which
cannot be fused.
• AssureLatch™ Technology positive-sealing latches keep the
cover securely in place while allowing for fast service.
• Cover label recess allows optional addition of application-
specific labels per end-customer requirements.
