The TE Connectivity Buchanan 796689-3 is a 3-position, single-level PCB terminal block on 5.00 mm pitch. It terminates solid or stranded wire from 12 AWG up to 30 AWG using a rising cage clamp — the screw tightens a brass clamp that pulls the wire against the current bar, giving a gas-tight connection without crimp lugs or ferrules. The 35° wire entry angle lets you route conductors at a shallow angle off the board, useful when the enclosure lid or adjacent components limit vertical clearance. Black polyamide (PA66) housing, rated 17.5 A at 300 V.
The Ratings That Matter for Your Fit
The 17.5 A per-position rating is the maximum at the rated temperature. The M3 screw with a specified torque of 0.79 Nm (7.0 Lb-In) is tighter than many mini-blocks. Wire range 12-30 AWG covers most control and power wiring in industrial panels. The rising cage clamp accepts both solid and stranded.
Ganging Multiple Blocks with Side Interlocking
The interlocking (side) feature lets you snap multiple 3-position 796689-3 blocks together into a longer assembly — 6, 9, 12 positions, and so on — without a separate jumper bar for the mechanical rail. The interlock keys align the blocks and prevent them from separating under vibration. If you need more than 3 positions in a single BOM line, stacking these is the intended method rather than ordering a single wider block.
