Product details

Barrier Strip for Panel and Chassis Wiring

The Molex 387203803 is a 3-circuit barrier strip from the Beau 38720 series, designed for panel or chassis mounting where a reliable, screw-terminated power distribution point is needed. The 0.375" (9.53 mm) pitch gives adequate spacing for 300 V working voltage and 25 A per circuit, with the dual-wall barrier providing physical isolation between adjacent terminals.

Top termination uses screws with a captive plate. Bottom termination is a solder turret, insulated. Wire range is 12-22 AWG. Terminal screws are steel with a zinc clear chromate finish.

Frequently asked questions

What is the pitch on the 387203803?

The pitch is 0.375" (9.53 mm) between centers.

Will the 387203803 drop into a panel cutout for the 387203204?

Yes — both share the same flange mount, dual-wall barrier, and 0.375" pitch, so the panel cutout and mounting pattern are identical. The 387203803 is 3 circuits; the 387203204 is 4 circuits, so the strip length differs by one position.

Where can I buy the 387203803 and how is it quoted?

The 387203803 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock-holding claim is made here.
