What this block is, and where it sits
The Beau 386608802 is a single-row, 2-circuit barrier strip from the Beau 38660 series — a through-hole power-distribution terminal designed to bring line and neutral (or two independent conductors) from a panel or DIN rail feed onto a PCB. The 0.500" pitch and PC-pin bottom make it a through-hole PCB-mount part; the captive-plate screw tops handle field wiring from 8-18 AWG without a ferrule. The 45A current rating at 600V is the headline number for this 2-position block — enough to handle a full branch circuit feed in a control panel or industrial power module. The rating applies per circuit, so both positions independently carry 45A simultaneously within the housing's thermal ceiling. The black PBT housing covers -40°C to 110°C, and the 3-wall (Tri) barrier construction between positions provides the required creepage and clearance for 600V service — a meaningful differentiator for high-voltage panel wiring over open-style terminal blocks.
Ratings that decide the fit
Wire gauge range 8-18 AWG covers heavy harness wiring down to relay-level signal gauge. The screw-head finish is zinc yellow chromate on steel — adequate for copper conductors, not a precious-metal plating, so no issue with galvanic compatibility for standard wire. Contact plating is not specified as a precious metal grade — this is a tin/steel termination system, which is appropriate for its class. If the application demands gold-plated contacts for frequent mating cycles or low-level signal, this is not that part.
What it is not — a note on the comparison candidates
The 0391002502 is a 2-circuit Eurostyle 39100 block — same circuit count, but 0.591" pitch, 63A rating, and chassis/panel mounting. The 386608802 is a 0.500" pitch through-hole PCB-mount block rated 45A. The pitch and mounting styles are fundamentally different; neither is a direct drop-in replacement for the other — they serve different mounting topologies.
Compliance and sourcing
The 386608802 carries ROHS3 Compliant status — the one compliance entry on this listing. No UL, VDE, or IEC certification appears on this specific part record.
