ABB EF19-1.0 Electronic Overload Relay EF19-1.0

ABB EF19-1.0 Electronic Overload Relay (model 1SAX121001R1102) is a three‑pole motor-protection device designed for low‑voltage, three‑phase circuits. It provides electronic overload protection for motors up to 690 V AC and covers a current range of 0.3 to 1.0 A, making it suitable for small to mid‑size motor applications. The trip current is adjustable, allowing precise tuning to motor startup and running conditions, and the unit is intended for use with ABB AF‑style contactors in motor starter configurations. As part of the EF19 family, the EF19-1.0 delivers compact electronic protection within a 3‑pole package, enabling reliable protection against overloads in industrial drive and automation schemes.
