Barrier Block for Power Distribution
The Molex Beau 38720 387207512 is a 12-circuit barrier terminal block built for panel and equipment power distribution. It carries 25 A per circuit at 300 V across a 0.375" (9.53 mm) pitch — the pitch is wide enough to handle the 12 AWG wire at the heavy end of its 12-22 AWG range without crowding adjacent terminals. The dual-wall barrier design physically separates each circuit, which reduces the chance of an accidental short when a screwdriver slips or a stripped wire strand bridges two positions. Top termination uses screws with captive plates — the plate stays under the screw head, so the wire wraps around the screw shank rather than pulling out from under a loose washer. Bottom termination is PC pin, meaning the block solders directly into the PCB through holes.
