The Allen-Bradley 193‑EA5DB overload relay is a Series B electronic overload relay designed to work with Allen‑Bradley 193‑series motor starters to protect motors in control-circuit applications. This Ser B variant sets to a current range of 1.0 to 2.9 amps, enabling precise protection for small to mid-range motors. As part of the 193 EA/EB/ES family, it integrates with the associated control circuitry via the overload trip contact arrangement and is wired in the control path to interrupt operation when an overload is detected.
