Westinghouse AR4A Control Relay

The Westinghouse AR4A Control Relay (MPN AR4A) is a panel‑mounted device designed for control circuit switching in industrial automation and control systems. It provides a 10 Amp current rating with a 600 Volt voltage rating and is energized by a 120 Volt coil, delivering reliable relay action for automation sequences in industrial facilities. This relay is intended for installation in industrial control panels and motor control systems, making it well suited for motor control centers, conveyor systems, processing equipment, and factory automation machinery that require robust control signal management. Applications focus on control circuit switching and auxiliary control functions within industrial automation environments, supporting durable performance in commercial and industrial settings. For legacy or aftermarket replacements, common options listed include Eaton D7PR4A, Allen-Bradley 700-P, and Square D 8501, reflecting its role in updating or replacing older relays in panel assemblies. Westinghouse AR4A serves as a dependable control relay within industrial automation and control applications, offering panel-mounted design and compatibility with systems that rely on solid relay switching for reliable operation in industrial control panels and motor control systems.
