The Molex Beau 38770 387700124 is a 24-circuit, dual-row barrier strip with a 0.375" (9.53 mm) pitch, designed for chassis or panel mounting in power distribution and control panels. It uses screw top termination and a closed bottom, accepting 14-22 AWG wire. The housing is black PBT rated UL94 V-0, and each circuit is rated 15 A at 300 V. This is the highest circuit-count member in the Beau 38770 series at 24 positions, giving you 48 wire entries in a dual-row layout. The flange on each end provides a secure bolt-down mount to a panel or chassis — no DIN rail adapter needed.
Ratings That Matter for the Fit
The 0.375" (9.53 mm) pitch is wide enough to give solid creepage for the 300 V rating — you won't have tracking issues between adjacent terminals even in a humid cabinet. The 15 A per circuit is a continuous rating; with 14 AWG wire landed under the zinc-plated steel screws, that current is limited more by the wire than the block. The dual-wall barrier design (2 Wall) physically separates each terminal pair, reducing the chance of a stray strand bridging circuits during wiring. The closed bottom means the screw terminals are only accessible from the top — no exposed conductors underneath the block.
The 387700118 is the 18-circuit version of the same Beau 38770 series — same 0.375" pitch, same 15 A / 300 V rating, same flange mount and screw termination. The only difference is the circuit count: 24 circuits here versus 18 on the 387700118.
