The part — what it is and where it sits in Beau 38720
The Beau 38720 series is a line of single-row barrier terminal strips — the kind of block engineers reach for when they need a wire-to-board or panel interconnect that a screwdriver can terminate without a crimp tool. The 387207506 is the 6-circuit member of that series, finished in black, with a 0.375-inch (9.53 mm) pitch and through-hole PC-pin tails for PCB mounting. Each circuit is rated 25 A at 300 V — the kind of headroom that covers most industrial control, lighting, and power-distribution wiring without needing to step up to a higher-voltage terminal block. Wire entry accepts 12-22 AWG solid or stranded conductors, and the top termination uses screws with a captive plate that holds the wire in place under vibration without the plate walking out of the slot as the screw is tightened.
What the ratings mean for the installation
The 2-wall (dual) barrier construction is the meaningful difference between this and a single-wall open strip. The enclosing side walls reduce the risk of accidental shorting between adjacent circuits during field wiring or in tightly bundled panels — important when the block sits near motor leads or other Class I wiring. The housing is thermoplastic rated UL94 V-0, so it holds in a panel enclosure fire scenario. Operating temperature range is -40°C to 100°C, which is wide enough for cold-storage control panels and equipment rooms alike. The terminal screws use zinc with clear chromate plating — adequate for indoor industrial environments; for outdoor or high-humidity installations the spec table does not show an enhanced corrosion option, so confirm the end-use environment before committing. Six wire entries match six circuits (one per circuit), so there is no multi-wire entry per circuit option on this position count. For a 6-circuit block carrying branched feeders, the 12-22 AWG wire gauge range gives enough flexibility to land heavier motor leads on the high-current circuits and lighter control wiring on the same block without mixing gauge inappropriately.
