The TE Connectivity Buchanan 282900-3 is a 3-position, single-level PCB-mount terminal block on a 0.197" (5.00 mm) pitch. It terminates wire via a screw-driven rising cage clamp — the screw pushes a clamp plate down onto the conductor, not the wire itself, so stranded conductors are captured without damage. The block is rated 17.5 A at 300 V, with a wire range from 12 AWG down to 30 AWG. It is through-hole soldered to the board, and the horizontal wire entry (parallel to the PCB surface) keeps the wiring profile low inside an enclosure. The green housing is standard for PCB terminal blocks in industrial control, power supplies, and lighting ballasts — the colour helps identify ground or neutral circuits at a glance.
The 17.5 A per-level rating is the headline spec — this is a power terminal, not a signal block. The 12-30 AWG wire range means you can land a 12 AWG power feed and a 30 AWG sense wire in the same block, which is useful for mixed-gauge harnesses in power distribution. The specified screw torque of 0.79 Nm (7.0 Lb-In) is the clamp force needed to meet the current rating — under-torquing raises contact resistance and risks thermal runaway at 17.5 A.
Termination and Field Service
The rising cage clamp accepts solid or stranded wire. The M3 screw is brass with nickel plating, and the clamp plate is brass-nickel as well.
