The TE Connectivity Buchanan 1546551-3 is a 3-position PCB-mount terminal block with a 0.138" (3.50mm) pitch, designed for wire-to-board termination using a screw-driven rising cage clamp. It accepts 16-28 AWG wire and is rated 12 A at 300 V, with a single-level, horizontal-with-board wire entry orientation. The green polyamide (PA66) housing is standard for ground/earth identification in panel wiring conventions, and the -40°C to 110°C operating range suits it for industrial control cabinets, HVAC equipment, and outdoor telecom enclosures where a reliable, field-serviceable screw termination is preferred over a crimp connector.
Key Ratings and Termination Detail
The rising cage clamp termination uses a nickel-plated copper alloy screw and clamp. The 16-28 AWG range covers most signal and low-power control wiring.
