Commercial Vehicle Product Datasheet HPDM SERIES POWER DISTRIBUTION MODULE 600 A • MEGA® Fuse • 2 Pole • Sealed • AssureLatch™ Description Specifications Overview 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. Max Voltage: 48 Vdc Max Input Current: 600 A Max Current per Circuit: 300 A Fuse Hardware: Fuse Torque: 4x M8x1.25 (included) 15 Nm Input/Output Hardware: Input/Output Torque: 1x M8x1.25, 3x M10x1.50 (sold separately) 20 Nm (Max install 300 RPM) Features and Benefits Mounting Hardware: Mounting Torque: 2x M8 (sold separately) 30 Nm Operating Temp: -50°C to +105°C Ingress Protection: IP67, IP69K Flammability Rating: UL94-V0 Dimensions: 129 x 125 x 45 mm • 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.
