Schneider Electric 8501-LO20 AC Magnetic Relay

Schneider Electric's Square D 8501-LO20 AC Magnetic Relay is a general-purpose NEMA control relay engineered for energizing and switching circuits in industrial equipment. The LO20 variant specifies a 110/120 V AC coil, enabling direct operation from standard line-voltage control circuits without additional power supplies. As part of the 8501 family, this relay embodies the robust magnetic actuation typical of Square D NEMA relays and is suited for logic elements and power-switching tasks within control panels, automation sequences, and process or HVAC/R systems. Its coil rating and Square D/NEMA classification align with common industrial control practices, offering a compact, reliable solution for coordinating signals and loads in a wide range of applications.
