Square D 8501XDO-20 AC Control Relay 120V 60Hz Coil

Square D 8501XDO-20 AC Control Relay is a NEMA-style machine-tool control relay from Square D (Schneider Electric). It provides two normally open contacts (2 Form A) and is driven by a 120 V AC coil rated for 50/60 Hz. The coil specification is 110/120 VAC, 50/60 Hz, aligning with common North American control circuits, while the contact rating is 10 A resistive at up to 600 VAC, enabling switching of light-to-moderate loads in control circuits for machinery and automation. The 8501XDO-20 variant belongs to the 8501 XDO family and is designed for use in control panels and machine-tool applications that require a two-form-A relay with a 120 VAC coil. Common applications include machine-tool control circuits and other automation tasks where a compact two-form-A relay with a 120 VAC coil is appropriate. This relay is manufactured by Square D (Schneider Electric), offering the rugged NEMA-style interface typical of the 8501 line and designed for interchangeability with related XDO relays in industrial environments.
