The new HWB60 sealed power distribution module (PDM), a compact PDM ideal for use in space-constrained vehicle battery compartments has a 60-slot HWB60. It accepts plug-in circuit protection components with a 280-style footprint, including Delphi MetriPack 280 connectors, terminals, cable seals, and cavity plugs. Standing up to road splash and salt spray, it provides robust protection to devices. With any combination of mini-fuses, relays, circuit breakers, and diodes, it handles the huge increase in added equipment used in today’s heavy-duty vehicles.
The compact sealed unit measures 113 x 52 x 82 millimeters (4.6 x 2.0 x3.2 in.) making it a perfect fit for accessory circuits, overflow circuits from the main PDM, or as a main module on smaller vehicles. The units are sealed to IP67 standards and can be installed virtually anywhere on the vehicle.
The elimination of internal bussing allows the user to customize circuitry with direct wire-to-component connections. In addition, the terminal position assurance (TPA) locks provide secondary locking protection for the wire leads, preventing them from being pulled out. TPAs snap onto the back after the wires are installed to ensure IP protection.
Being modular, the units can be dovetailed together to expand circuit protection capacity. They can also be interlocked to other Littelfuse PDMs and fuse holders, including FLEC, MEGA Flex holder, and MIDI Flex holder, to provide complete system protection.
