387206303 Beau 38720 Barrier Block, 3-Circuit, 0.375" Pitch, 15 A

The 387206303: The Beau 38720 barrier strip is a single-row, 3-circuit dual-wall terminal block rated 15 A per circuit at 300 V, with a 0.375-inch (9.53 mm) pitch. Wire entry is at the top via screw clamps accepting 14-22 AWG; the bottom terminates to PCB pins — the screw-top and pin-bottom pairing makes this suited for panel feed-through or single-sided board entry where the field wiring lands on the connector face and the board connection runs vertically down to the PCB. The housing is black thermoplastic rated UL94 V-0 with an operating range of -40°C to 100°C — solid for industrial panel environments where derating from thermal cycling is a design concern. Terminal screws are steel with a zinc clear chromate finish — adequate for the wire sizes this block accepts, though in corrosive environments a nickel-plated alternative in the same series would be worth confirming.
