Square D CO-6 is a Class 8501, Type CO-6 power relay (contactor) used to switch small single‑phase loads in control circuits. The CO6V20 variant is a 120 V AC coil, rated up to 30 A with 1‑pole SPST normally open contacts and panel‑mount operation. The CO6V04 variant uses a 277 V AC coil with the same general 30 A rating and a single‑pole, normally open configuration. The CO6V24 variant provides a 24 V coil and SPDT contacts (1 NO and 1 NC), also rated to 30 A at up to 300 VAC, making it suitable for switching small motors, heaters, and other light loads.
