Buchanan 10-Position PCB Terminal Block with Rising Cage Clamp
The TE Connectivity Buchanan 1-282851-0 is a 10-position, single-level PCB terminal block with a 5.08 mm pitch, designed for top-entry wire termination via a rising cage clamp mechanism. The green polyamide (PA66) housing is rated for 300 V and 17.5 A per position, with an M3 screw torqued to 0.79 Nm (7.0 Lb-In) to secure wires from 12 to 30 AWG. The interlocking side feature allows multiple blocks to be ganged side-by-side without additional hardware, creating a continuous terminal strip for multi-circuit power distribution.
Rising Cage Clamp Termination and Wire Range
The rising cage clamp termination pulls the wire up against a brass, nickel-plated clamp plate as the M3 screw is tightened, providing a gas-tight connection that resists loosening under thermal cycling. The 12-30 AWG wire range covers both heavy power conductors and fine signal wires, making this block suitable for control panels, power supplies, and industrial I/O modules. The brass, tin-plated contact material ensures reliable conductivity for the 17.5 A rating at the rated 300 V.
Interlocking Side Feature for Multi-Block Ganging
The interlocking side feature allows the 1-282851-0 to be mechanically linked to adjacent Buchanan blocks of the same pitch, forming a continuous terminal strip without gaps. This is useful when the circuit count exceeds 10 positions — simply add another block and snap the interlock. The 5.08 mm pitch remains consistent across the ganged assembly, maintaining uniform PCB hole spacing.
