Bus Bar Connector (BBC) FEATURES AND SPECIFICATIONS 45711 Vertical Mount Hot-Pluggable, High-Current Bus Bar Connector (BBC) Provides An Easy Blind-Mate Connection New telecommunication and high-end computing equipment require increasing amounts of current from power supplies. To meet this challenge, Molex is pleased to expand its product offering of high-current connector solutions with the BBC. The BBC is a compact, high current connector for direct mating of two perpendicular power bus bars in a power supply or switching power supply application. Rated up to 320.0A, 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 freefloat 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. Perpendicular bus bars Molex Bus Bar Connector (BBC) Features and Benefits ■ Top entry of the connector mates with a standard 25.40mm (1.000”) wide by 3.18mm (.125”) thick bus bar tab which facilitates mating with de facto output blades for typical power supply applications ■ Rated up to 320.0A 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) to match true hot-plugging requirements ■ Dimensionally compatible with competitive connectors assures drop-in replacement for second source opportunities ■ Low-voltage drop for minimal heat generation ■ Float-mount design provides up to 6° of misalignment to blind-mate with bus bar tab ■ Mounts to a bus bar via two, 4.32mm (.170”) diameter holes using customer supplied (8”x32” thread) machine screws providing screw-mount design for secure fastening to bus bar SPECIFICATIONS Reference Information Packaging: Bag UL File No.: Pending CSA File No.: LR 19980 TUV File No.: Pending Mates With: 25.40mm (1.000”) x 3.18mm (.125”) Thick Bus Bar Tab Designed In: Inches Electrical Voltage: 600V Current: 320.0A max. per contact set Contact Resistance: 20 milliohms max.
