A wrap around bus bar that provides battery power (also referred to as B+ power) to components within a power distribution device for a vehicle electrical system, such as a hybrid-type power distribution box (PDB). The power distribution device routes or distributes power throughout a vehicle electrical system and may include a lower cover, a wrap around bus bar, a relay block assembly, a module with a printed circuit board (PCB), an array of relays and fuses, and an upper cover. Battery power is provided from a vehicle battery and/or alternator to a terminal connection, from the terminal connection to the wrap around bus bar, and from the wrap around bus bar to the relay block assembly, the module and potentially other components within the power distribution device.

A fuse header includes a housing with cavities and terminals mounted in the housing adjacent the cavities. Fuses can be mounted removably in the cavities so that the fuses connect to the terminals in the respective cavity. Ends of the terminals opposite the fuses have widths that are narrowed substantially and may equal the thickness of the terminals. The narrow widths impede a flow of heat from the fuse to large conductive regions on a circuit board that could function as a heat sink. Thus, the fuses will provide more reliable protection for components downstream of the fuses.

A switchable socket assembly () permits a power source to be changed. The switchable socket assembly () includes a switch guide () that communicates with a linear array of terminal fittings that include an output terminal fitting () and first and second input terminal fittings () on opposite respective sides of the output terminal fitting (). A switch () is slidable in the switch guide () and can be moved between first and second positions. In the first position, the switch () permits a fuse () to connect to the output terminal fitting () and the first input terminal fitting (). In the second position, the switch () permits the fuse () to connect to the output terminal fitting () and the second input terminal fitting ().

A fuse and relay block assembly () for an automotive vehicle includes a lower cover () and an upper cover () mounted in substantially opposed relationship to one another. A relay block () is mounted between the lower cover () and the upper cover () and can receive electrical devices (R, F) mounted along a mounting direction (MD). A relay module assembly () is mounted between the lower cover () and the upper cover () and can receive electrical devices (R, F) mounted along a transverse direction (TD) substantially perpendicular to the mounting direction (MD). Thus, a greater density of electrical devices (R, F) can be mounted within a smaller footprint.
