Schneider Electric SE 8501G0-40 Control Relay

Schneider Electric's Square D 8501G0-40 is an open-type, general-purpose NEMA control relay in the 8501 family. It operates from a 120/277 VAC coil and provides a 10 A switching capability for AC loads, making it suitable for energizing auxiliary devices, signaling circuits, or small contactors in electrical control panels. The 8501G0-40 configuration is designed for panel-mounted, open installations and is compatible with other 8501 accessories within the Square D lineup, enabling straightforward replacement or integration into existing control schemes. This model is commonly used in industrial automation to translate a low-current control signal into a higher-current circuit, supporting reliable operation in machines, conveyors, timers, and equipment controllers that require a robust, field-installable relay with global AC compatibility. By sticking to the established 8501 family footprint and ratings, the 8501G0-40 delivers predictable performance in standard environments where a compact, open-type relay is needed for control logic and interlock circuits.
