BREAKERS BUC730U20 Definite Purpose Contactor

BUC730U20 Definite Purpose Contactor, Breakers Unlimited, is a three‑pole device rated for 75 A full‑load amps with a 120 V AC coil, designed to switch AC motor and compressor loads in dedicated equipment. It is commonly used in applications such as HVAC units, pumps, and refrigeration systems where a compact, purpose‑built control switch is required for 120 VAC control circuits. In keeping with Bulletin 400 Definite Purpose contactors, this type supports field‑installable auxiliary contact blocks (up to two blocks, one on each side, four contacts max) and, for sizes 40 A and larger, box lugs are standard. For those seeking a compatible OEM replacement, ACC730U20 is listed as a replacement part for similar 75 A, 120 V DP contactors.
