Panel Wiring: 2-Circuit Barrier Block for Control Cabinets
The Molex Beau 38720 0387206202 is a 2-circuit barrier terminal block designed for panel-mounted wiring in industrial control equipment. It carries a 15A current rating at 300V, with a 0.375" (9.53mm) pitch that gives enough terminal spacing to accept 14-22 AWG wire comfortably. The dual-wall barrier between circuits reduces the risk of flashover in dirty or humid cabinet environments. Termination is straightforward: field wires land under the screw clamp on top (steel screw with zinc clear chromate finish), and the circuit connects to the PCB through a PC pin on the bottom. The flange on each end lets you bolt the block to a chassis or panel — useful when the wiring sees vibration or when the screw torque needs a solid anchor. This is the smallest circuit count in the Beau 38720 series — a two-position block for a single power feed or a fused disconnect pair.
Wiring and Torque: What the Screw Termination Expects
For 14 AWG stranded wire, tighten the screw until the conductor is clamped firmly; the dual barrier walls keep the screwdriver from bridging to the adjacent terminal.
RoHS compliance is standard for current-production Molex barrier blocks; the PBT housing and zinc-plated steel hardware meet the directive. No separate UL or CSA listing number is stated in the spec, but the UL94 V-0 rating on the insulation material is a common requirement for equipment inside a UL 508A industrial control panel.
