Schneider Electric's Square D 8501 CO-2 AC control relay is an open-frame relay with DPST (two normally open) contacts designed to switch AC loads in control circuits. It uses a 120 V AC coil (60 Hz), enabling operation from standard 120 VAC control signals. This 8501-class device is suited for rugged industrial panel applications where a compact, reliable relay is required to energize auxiliary circuits.
