Appleton ACP3044BC Powertite Pin and Sleeve Clamping Ring Plug

Appleton ACP3044BC Powertite Pin & Sleeve Clamping Ring Plug delivers a rugged 30 A, 600 VAC pin‑and‑sleeve connection in a 4‑pole, 4‑wire configuration for industrial power delivery. As part of the Powertite Series, this metallic clamping ring plug is built to mate with compatible receptacles for portable or fixed equipment in harsh environments, and is documented as a replacement for AEP3451 in some harnesses. The plug supports 50–400 Hz operation with a 250 VDC rating and accommodates conductors sized to 10–6 AWG (10–8 AWG for extra‑flex applications), making it suitable for heavy‑duty power applications. Grounding Style 1 configurations are typical for this style, and the assembly remains NEMA 4X rated when the clamping ring is fully tightened on the connector body, yielding reliable protection against dust, water, and corrosion. Common applications include powering motor generators, welders, pumps, compressors, and cellular relay stations, where a durable, four‑wire power connection is required in demanding industrial settings.
