What it is
The Beau 386907602 is a 2-circuit barrier block in the Beau 38690 series — a single-row, flange-mount terminal strip sized for 12–22 AWG wire. The top termination uses screws with a captive plate that retains the wire against vibration and repeated torquing without the plate walking out of the housing. The bottom termination is a PC pin designed for through-hole board mount. The 0.325" (8.26 mm) pitch, 20 A per circuit, and 300 V rating place this block in the mid-range of industrial power-distribution terminal strips.
What the ratings mean
The 20 A current rating is per circuit, and the 12–22 AWG wire-gauge range tells you the block is intended for power bus wiring within a panel — not signal-level interconnect. At 300 V it covers industrial bus voltage levels. The operating temperature limit of 110 °C is set by the thermoplastic housing; the block is UL94 V-0 rated. The 3-wall (tri) barrier construction adds mechanical isolation between adjacent circuits beyond what an open-barrel strip provides — the side walls reduce the chance of a tool or stray strand bridging two circuits during field termination. The flange gives a mounting point for a screw or bolt to secure the block to a panel face or DIN-rail adapter plate.
Where this class is used
Barrier blocks like the 386907602 are the workhorse of industrial panel power distribution — they appear on the input side of contactors, as bus-tap points for branch circuits, and at the field-termination interface of panel-built equipment. The screw-top accepts ring or fork terminations and survives field torquing in a way that spring-cage or push-in blocks sometimes cannot in high-vibration environments.
Sourcing and compliance
The 386907602 carries an Active lifecycle status and is ROHS3 Compliant. It ships in tray packaging. No official successor or cross-reference is on record for this MPN — the Beau 38690 series itself is the reference family for alternate sources within that series.
