Beau 38720 — 4-Circuit Barrier Block
The Molex 387207204 is the 4-circuit member of the Beau 38720 series, a dual-wall barrier terminal strip rated 15 A per circuit at 300 V. The 0.375-inch (9.53 mm) pitch sets the footprint for single-row through-hole PCB mount; top termination is screws accepting 14–22 AWG wire, and the bottom terminates to a PC pin for wave or hand-solder into the board. The black thermoplastic housing carries a UL94 V-0 flammability rating and operates from -40°C to 100°C — wide enough for most control-cabinet environments. Nickel-plated brass terminal screws torque down on the conductor without the cold-flow creep that plagues unplated brass in vibration-prone panel runs. At 4 wire entries and 4 circuits in a single row, this is a compact distribution point for field wiring — the dual-wall barrier gives the creepage needed between adjacent live screws in a 300 V circuit without requiring an enclosed body.
