This is a through-hole mounted block that sits vertical to the board, making it a straightforward fit for power distribution and control wiring on a PCB — the kind of block you see in industrial power supplies, HVAC controllers, and panel-mounted I/O boards. The 17.5 A per-position rating and 300 V voltage rating put it in the power-termination class, not signal-level. ## Termination and wire handling The rising cage clamp is the workhorse termination here — you strip the wire, insert it into the clamp opening, and tighten the M3 screw to 0.79 Nm (7.0 Lb-In). The clamp pulls the cage up against the wire, trapping it against the current bar. No crimp terminal, no ferrule required, though a ferrule helps with stranded wire in the 12-30 AWG range. The screw and clamp are brass with nickel plating, the contact bar is brass with tin plating — tin is standard for this class of block and holds up fine under the screw pressure. The interlocking side feature means multiple blocks can be ganged side-by-side on the same PCB without gaps, which is useful when you need more than 8 positions in a row.","metaTitle":"1546073-8 Buchanan Terminal Block, 8 Pos, 5.08mm, 17.5 A","metaDescription":"1546073-8 Buchanan PCB terminal block, 8 positions, 5.08 mm pitch, 17.5 A, 300 V, screw rising cage clamp, active production, ROHS3.
