What it is
The Molex 387207502 is the 2-circuit member of the Beau 38720 dual-wall barrier strip series — a single-row, through-hole terminal block with a 0.375 inch (9.53 mm) pitch and a 300 V rating. Wire enters from the top through a captive screw plate that clamps conductors from 12–22 AWG without fraying strands; the bottom terminates to a PCB-ready PC pin for through-hole reflow or hand-solder assembly. The housing is black thermoplastic rated UL94 V-0, and the operating window spans -40 °C to 100 °C — wide enough for most panel and industrial control enclosures without derating the current below the 25 A per circuit ceiling. The terminal screws carry a zinc clear-chromate finish over steel, providing corrosion resistance in field-wired environments where the block sees repeated torque cycles during installation and maintenance.
Where it sits in the series
The Beau 38720 series uses a dual-wall (enclosed) barrier construction that contains arcing and spatter better than open-frame blocks — the 2-circuit count here is the series minimum, with larger circuit-count variants sharing the same 0.375 inch pitch, screw-top / PC-pin termination pattern, and wire gauge window. Because the full series shares pitch and mounting footprint, a panel cutout and PCB land pattern designed for any 38720 member accepts this 2-circuit block as a direct fit — useful when the BOM specifies a smaller circuit count than the original build and a panel re-layout is not an option.
