Littelfuse HWB Hard-Wired Power Distribution Modules
Littelfuse HWB Hard-Wired Power Distribution Modules (PDMs) offer designers a variety of improvements in dealing with electrical system design challenges. HWB modules are available to accommodate from 3 (HWB6) to 30 (HWB60-AL) mini (2.8mm) plug-in circuit protection components. Littelfuse HWB PDMs are small enough to be installed almost anywhere the flow of electrical power must be protected or controlled.
All Littlefuse HWB sizes are waterproof to protect the components inside from corrosion due to road splash, salt spray, and dust intrusion. HWB6, HWB12, HWB18 and HWB60-AL have Ingress Protection ratings of IP67 (total protection from dust and protected from temporary liquid immersion) and IP69K (proven to resist ingress of high temperature and pressure wash). Each unit except HWB18 has two AssureLatch™ yellow positive-sealing latches that open easily to remove the cover for component replacement. The latches combine with the unit’s gasket to keep the cover sealed securely against water and dirt intrusion. Thee hard-wired PDMs also accomodate a varied mix of circuit protection components.
