Schneider Electric SE 8501C07V20 Power Relay

Square D 8501C07V20 is a general‑purpose, open‑frame power relay from Schneider Electric’s Square D line, with a 120 VAC coil that switches AC loads in control circuits. It uses a DPST (2 Form A) contact arrangement—two normally open contacts—and is rated for 30 A of resistive current up to 300 VAC, suitable for medium‑duty switching in panels and automation equipment. The 8501C07V20 is the SER.B variant designed for through‑panel mounting with a six‑pin base and compatibility with standard Square D open‑frame sockets. Coil voltage is 120 VAC at 50/60 Hz, and the device measures roughly 2.5 in wide by 2.49 in high by 2.25 in deep, making it straightforward to tuck into control panels where space is at a premium.
