What this is
The Molex 387216706 is the 6-circuit member of the Beau 38721 barrier-strip series — a single-row, flange-mount terminal block rated 15 A per circuit at 300 V, with a 0.375-inch (9.53 mm) pitch that sets the spacing between wire entries.
What the ratings mean for panel fit
The 15 A per circuit rating uses the dual-wall barrier construction and steel screw hardware with zinc clear-chromate finish — the screw clamp is the current-carrying path, so torque specification matters during installation. The 300 V rating sets the creepage distance at the wire entry spacing; check this against your equipment's insulation class if the application runs close to line voltage. The flange feature provides a registered mounting face against a chassis or panel surface — the glass-filled PBT housing carries a UL94 V-0 flammability rating, which satisfies most industrial enclosure requirements for self-extinguishing plastic in end-use equipment. Operating temperature range of -40°C to 100°C covers the typical ambient extremes inside a sealed enclosure or on an open industrial panel; the PBT glass-filled body resists moisture absorption better than unfilled nylon in long-term field service.
Termination and wire gauge
Top termination is screw-clamp accepting a single 14-22 AWG conductor per circuit — the six number of wire entries matches the six circuits, so each position is a dedicated single-wire entry with no commoning jumpers built in. Bottom termination is a Quick Connect (0.187-inch) insulated tab, which provides a fast-field-disconnect option for the load side without disturbing the panel wiring on the screw side. The 14-22 AWG range covers the lighter end of industrial control wiring — conductors at the lower end of the range work within the 15 A per-circuit rating; verify against the applicable derating curve if the enclosure runs hot.
