Allen-Bradley 193-EF1A Solid-State Overload Relay

Description

Allen-Bradley 193-EF1A Solid-State Overload Relay is a member of Allen-Bradley’s 193 series electronic motor protection devices. While specific technical data for this exact model is not available, based on comparable 193 series solid-state overload relays, it is designed to provide 3-phase motor protection against overcurrent conditions. Similar models in the line offer features like adjustable current ranges, selectable trip classes (typically 10, 10-30), and solid-state construction for reliable, fast-acting protection without moving parts. For reference, related 193 series models include the 193-ED1EB, a 3-phase solid-state overload relay with a 5.4-27A current range and trip class 10; the 193-EEEB Ser C E1 Plus, a 3-phase unit with a 5.4-27A range; and the 193-EEBB Ser. C, which covers a 0.2-1.0A range with trip class 10-30. These relays are engineered to monitor motor current continuously, triggering a trip to disconnect power if current exceeds safe levels, preventing motor damage from overheating due to overloads, phase loss, or unbalanced currents. They are suitable for use with industrial AC motors in manufacturing, automation, and machinery applications.
