It is a single-row, through-hole component with a 0.438\" (11.12 mm) pitch, designed for wire-to-board power distribution in industrial control panels, power supplies, and HVAC equipment. The dual-wall barrier construction provides physical isolation between adjacent circuits, reducing the risk of accidental shorting during field wiring or maintenance. Rated 25 A at 600 V, this block handles motor starter feeds, lighting contactor circuits, and similar branch-level loads where a single-row, low-circuit-count termination point is needed. The 12-24 AWG wire range covers most field-installed power and control conductors, and the screws with captive plate top termination clamp the wire without damaging stranded conductors. The 0.438\" (11.12 mm) pitch is a standard spacing for barrier blocks in this current class. It gives enough room between PC pins for routing board traces and for a screwdriver to comfortably reach the terminal screws without bridging adjacent positions. The through-hole PC pin bottom termination means the pins drop into the board and are wave-soldered — no press-fit or SMT reflow.","metaTitle":"Molex Beau 386307803 Barrier Strip, 3 Circuits, 0.438\" Pitch, 25 A","metaDescription":"Molex Beau 38630 barrier strip terminal block, 386307803, 3 circuits, 0.438\" pitch, 25 A, 600 V, through hole, PC pin, black PBT, RoHS3.

The 386307804 has 4 circuits versus the 386307803's 3, and the PC pin footprint is one position longer. The pitch, current rating, and voltage rating are identical, so it will work electrically if the extra position is acceptable in your panel layout."},{"question":"Where can I buy the 386307803 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
