What this block is
The Molex 387700116 is the 16-circuit member of the Beau 38770 barrier strip series — a dual-row, flange-mount terminal block built for chassis and panel wiring in industrial control and power distribution applications. It carries a 0.375" (9.53 mm) pitch between circuits and is rated 15 A per circuit at 300 V, with screw-top termination that accepts 14–22 AWG conductors across 32 wire entries (two per circuit).
What the ratings mean for the fit
The 15 A per-circuit rating at 300 V sits within the typical range for panel-wiring barrier blocks — pair it with 14–16 AWG for headroom on longer runs, and the screw clamp holds the full conductor cross-section without cold flow. The 0.375" pitch is the Beau series standard; it is not the same spacing as the 0.394" Eurostyle series (0391002012), so a panel cutout built around one will not accept the other without rework. The PBT housing carries a UL94 V-0 flammability rating — that is the flame-retardance level required in enclosed panel enclosures for industrial automation. The zinc clear-chromate screw finish resists corrosion in field conditions, and the flange mounting provides a secure reference face on the panel surface.
Lifecycle and compliance
The 387700116 is listed Active and ROHS3 Compliant — standard procurement posture for an in-production industrial terminal block. No official successor or cross-reference is on record for this exact circuit count in the Beau 38770 series.
