The Molex 0387244903 is a 3-circuit terminal block from the Beau 38724 series, a barrier strip family designed for point-to-point wiring in power distribution and control panels. It uses a 3-wall (tri) barrier design to isolate adjacent terminals, reducing the risk of accidental shorting between circuits. Rated 25A at 300V, it handles motor branch circuits, industrial relay outputs, or field-wired sensor power where a single-row, low-circuit-count block is sufficient. The 0.375" (9.53mm) pitch gives enough spacing for 12-22 AWG wire termination without crowding adjacent terminals. The PBT insulation also provides the flame retardance expected for equipment installed inside a UL-listed panel.
Termination and Field Wiring
This is a practical detail for a technician landing multiple wires in a panel: no loose washers to retrieve from the bottom of the cabinet. Wire range is 12-22 AWG, covering the most common power and control wiring sizes. The three wire entries match the three circuits — one wire per position, no daisy-chaining through the block itself.
