Molex Bus Bar


Hot-Pluggable, High-Current Bus Bar Connector (BBC) Provides An Easy Blind-Mate Connection

The BBC is a compact, high current connector for direct mating of two perpendicular power bus bars typically found in power supply or switching power supply applications. Rated up to 320A, the BBC offers over 20% more current than competing products. The higher current provides increased power or safety factor for customer applications. The high performance, contact design offers true hot pluggability. The parallel contacts free-float within the BBC housing to facilitate blind mating with the bus bar tab. The BBC's mounting dimensions are identical to competing connectors for easy second sourcing opportunities.


  • Top entry of the connector mates with a standard 25.40mm (1.000") wide by 3.18mm (.125") thick bus bar tab
    • Facilitates mating with de facto output blades for typical power supply applications 
  • Rated up to 320A
    • For high-current applications
  • Isolated left and right contacts
    • Provide option for power feed and return when BBC is mounted to a laminated bus bar
  • Rated for current interruption (Safety agency approvals pending)
    • Matches true hot-plugging requirements
  • Low-voltage drop
    • For minimal heat generation
  • Float-mount design
