The TE Connectivity Buchanan 796740-3 is a 3-position PCB terminal block from the Buchanan series, designed for wire-to-board power connections in industrial control panels, HVAC equipment, and power supplies. It uses a screw-driven rising cage clamp to secure 10-24 AWG wire against a brass-nickel plated clamp, delivering a rated 30 A at 300 V per position. The 0.250 inch (6.35 mm) pitch gives enough spacing between adjacent terminals to handle the 300 V rating without tracking across the board surface. The green polyamide 6/6 housing is standard for the Buchanan family and provides UL94 V-0 flame resistance for equipment inside an enclosure.
Wire termination is by screw rising cage clamp — the M3 screw is torqued to 0.79 Nm (7.0 Lb-In), which lifts the cage to clamp the conductor against the current bar. This gives a gas-tight connection that resists loosening under thermal cycling. The mating orientation is horizontal with the board, meaning the wire entry is parallel to the PCB surface — useful when the board is mounted vertically in an enclosure and wires run along the backplane. Through-hole mounting with the interlocking side feature lets you snap multiple blocks together side-by-side to build a multi-position strip without separate jumpers.
