The Allen-Bradley 592-A1CA SMP-1 solid-state overload relay provides precise overload protection for 3‑phase NEMA starters in Starter Size 00 configurations, with a full-load current adjustment range of 0.32 to 1.0 A. It uses a manual reset mechanism and delivers Class 10 trip performance to interrupt motor current when overload is detected. As part of the 592 SMP family, the A1CA model is designed to accompany Allen-Bradley NEMA starters to safeguard small- to mid-size motors from overload conditions in light-industrial applications.
