The Molex 0387206212 is a 12-circuit barrier terminal block from the Beau 38720 series, built for panel-mount or through-hole power distribution. The dual-wall barrier (2 Wall (Dual) construction) separates adjacent terminals with a molded PBT wall on both sides of the screw, which prevents wire strands from bridging between positions during termination.
Wire Range and Termination — What Actually Connects
Top termination is screw-clamp — the steel screw with zinc clear chromate finish bears directly on the wire. Wire acceptance is 14-22 AWG, which covers the common range for 15 A branch circuits in control wiring and power distribution. The 12 wire entries match the 12 circuits exactly — one wire per position, no shared terminals. The flange feature on each end provides a screw-down mounting point to the panel, taking mechanical strain off the solder joints.
