What it is
The Molex 386608805 is the 5-circuit member of the Beau 38660 Tri-barrier block family — a through-hole panel-mount terminal block rated 45 A per circuit at 600 V, with a 0.500-inch (12.70 mm) pitch that positions five screw-terminal entries on a single row. Wire entry accepts 8–18 AWG via top screws with a captive plate that retains the conductor under vibration and thermal cycling — the plate keeps the wire seated without cold-flow creep that plain clamp screws develop over long field service. Bottom termination is a PCB pin designed for through-hole reflow or wave-solder into a backplane or control-card header — making this a board-edge barrier block rather than a pure panel-chassis block.
Ratings that decide the fit
The 45 A per circuit rating governs bus-bar and distribution-panel duty; the 600 V rating covers most AC and DC industrial control rails up to that ceiling — these two figures together define whether this block handles the power trunk or a branch tap. The 3 Wall Tri-barrier geometry provides double-creepage protection between adjacent circuits — relevant when bare conductors or uninsulated ring terminals sit under the screws in high-voltage panel runs. Operating temperature range is -40°C to 110°C; the PBT housing material sets the upper limit, so a panel ambient above 110 °C rules this part out regardless of current. Terminal screws carry a zinc yellow chromate finish — adequate for indoor industrial environments; for salt-mist or outdoor exposure a nickel-plated or stainless alternative from the same series should be evaluated.
Lifecycle and compliance
marks this part Active with ROHS3 Compliant status — no last-time-buy signal on record, and no declared obsolescence or NRND notice in the ledger. ROHS3 is the only third-party compliance certification on record for 386608805; no UL, VDE, or IEC type-certification entry appears in the current listing — if a standards-stamped panel certificate is required, confirm with the manufacturer before specifying.
