Schneider Electric 8501-G0-20 Industrial Control Relay

Schneider Electric's Square D 8501-G0-20 industrial control relay is a 8501-class AC control relay with two normally open contacts and a 120 V AC coil. The GO-20 configuration denotes a two-NO setup within the modular, cartridge-style 8501 platform, designed for plug-in replacements in control panels and automation cabinets. This lineage is built for rugged, general-purpose automation—Square D's 8501 relays are widely used in industrial control applications where energizing the coil closes the NO contacts to switch loads. The family emphasizes modular construction, allowing technicians to swap contact cartridges or tailor configurations without replacing the entire relay body, a design approach that supports compact control panels and straightforward maintenance. Availability of GO-20 variants in the market, including 120 V AC versions, reflects the broad adoption of 8501 relays in standard industrial control schemes.
