Allen-Bradley 592-A2CA is a manual-reset, eutectic-alloy thermal overload relay for protecting small motors in NEMA starter assemblies, offering a 0.32–1.0 A full-load current adjustment range. It is designed for installation on Starter Size 00 configurations and is part of Bulletin 592’s family of eutectic overload relays. The relay uses a temperature-sensitive eutectic element to trip when motor current exceeds the set point and requires a manual reset after a trip, providing straightforward, field-serviceable motor protection in compact control panels.
