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.","metaTitle":"Molex Beau 38724 0387244903 Barrier Block, 3 Circuit, 25A","metaDescription":"Molex 0387244903 Beau 38724 series 3-circuit barrier block, 0.375\" pitch, 25A, 300V, screws with captive plate, PC pin termination, through-hole, black PBT","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Terminal Blocks"],"specifications":{"Color":"Black","Pitch":"0.375\\\" (9.53mm)","Series":"Beau 38724","Features":"-","Packaging":"Bulk","Wire Gauge":"12-22 AWG","Part Status":"Active","Barrier Type":"3 Wall (Tri)","Manufacturer":"Molex","Mounting Type":"Through Hole","Number of Rows":"1","Voltage Rating":"300V","Top Termination":"Screws with Captive Plate","lifecycle_stage":"unknown","Bottom Termination":"PC Pin","Number of Circuits":"3","Base Product Number":"038724","Terminal Block Type":"Barrier Block","Current Rating (Amps)":"25A","Material - Insulation":"Polybutylene Terephthalate (PBT)","Operating Temperature":"-40°C ~ 100°C","Terminal Screw Finish":"Zinc, Clear Chromate","Number of Wire Entries":"3","Terminal Screw Material":"Steel","Material Flammability Rating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch and circuit count for 0387244903?","answer":"The pitch is 0.375\" (9.53mm) and it has 3 circuits in a single row.
