Square D 8501 GO-20 Industrial Electrical Control Relay

Square D 8501-GO-20 AC control relay from Schneider Electric is a compact, NEMA‑style device designed to energize and switch control circuits in industrial equipment. A member of the 8501 relay family, the GO‑20 variant is specified for 110/120 V AC control power with 50/60 Hz operation, aligning with common plant control supplies and machine-tool circuits. The relay uses a magnet coil to actuate its contacts, delivering dependable actuation in panel‑mounted or equipment‑mounted installations. Typical applications include relaying pilot signals, interlocks, and sequencing logic within industrial control panels and automation circuits, where a dedicated control relay is used to drive auxiliary circuitry without carrying heavy power loads through the same path. This model supports Square D accessory and socket ecosystems, helping streamline wiring, maintenance, and replacement in medium‑duty control schemes. In environments where standard Square D 8501 components are already in use, the GO‑20 variant provides a familiar, robust option for small‑to‑mid sized control tasks that rely on a readily available, widely supported relay platform.
