What it is and where it fits
The Molex 387206202 is the 2-circuit member of the Beau 38720 series of barrier strip terminal blocks — a single-row, flange-mount block with a 0.375-inch (9.53 mm) pitch and screw-top entry on the wiring side, PC-pin through-hole termination on the board side. Rated 15 A per circuit at 300 V, it accepts 14–22 AWG wire at the screw clamp and mounts directly to the chassis or panel via through-hole legs. The PBT housing carries a UL94 V-0 flammability rating across an operating range of -40°C to 130°C, making it suitable for industrial control and power distribution panels where wire retention and panel-side solderability are both required.
Ratings that drive the selection
Rated 15 A per circuit at 300 V, the 14–22 AWG wire gauge range covers the common industrial panel gauge span. The dual-wall (2-wall) barrier construction adds mechanical robustness to the wire entry side, and the flange feature provides a secondary panel attachment point beyond the through-hole pins alone. Operating temperature to 130°C covers the hot-side of most enclosed panel environments. The zinc-clear-chromate terminal screw finish over steel provides corrosion resistance suitable for indoor industrial environments; for outdoor or chemically aggressive atmospheres a different screw finish would be needed — this is not stated on the listing, so confirm with the datasheet if the application is harsh.
