Abstract: An environmentally sealed power distribution module is disclosed having a hybrid peripheral seal disposed around a power distribution panel and within an interface between a top housing and a base housing. The peripheral seal is comprised of a traditional o-ring type seal having an open segment and a gel pad type seal located within the open segment, thereby completing the peripheral seal. Plate-like power distribution bus bars are reliably sealed by the gel pad type seal as the bus bars exit the power distribution module. A sealed releasable cover is provided to access fuses and other electrical components of the power distribution module.
