The TE Connectivity Buchanan 1-1546073-0 is a 10-position, single-level PCB-mount terminal block on a 0.200" (5.08mm) pitch. It terminates wires via a screw-driven rising cage clamp — the screw turns to lift a clamping plate that grips the conductor against the current bar, giving a gas-tight connection that holds up under thermal cycling. Rated 17.5 A at 300 V, it handles power distribution inside industrial control panels, HVAC equipment, and machinery junction boxes where field wiring needs to be landed and re-landed without replacing the block.
The rising cage clamp accepts 12 AWG to 30 AWG wire. The M3 screw has a torque spec of 0.79 Nm (7.0 Lb-In).
Through-hole mounting with 0.200" (5.08mm) pitch — the hole pattern and pad size follow the standard footprint for this pitch class. The interlocking side feature lets you gang multiple blocks side-by-side on the same pitch to build a multi-position strip without gaps, sharing the same screw-down centres. The black PA66 housing is UL94 V-0 rated by material class, though the specific rating isn't listed here — the nylon 6/6 construction is the standard flame-retardant grade for panel-mount terminal blocks.
