Allen-Bradley 193-EC1AB Electronic Overload Relay

Allen-Bradley 193-EC1AB Electronic Overload Relay is a solid-state motor protection device in Rockwell Automation’s Bulletin 193 family that safeguards AC motors up to 600 V with an adjustable overload threshold of 1–5 A. It is designed for direct mounting to compatible Allen-Bradley contactors and wiring configurations, enabling a compact, integrated motor protection solution with common compatibility to Bulletin 300-A and several 100-C09/12/16/23 contactors. As part of the E3 Electronic Overload Relay line, the 193-EC1AB provides fast, reliable protection to help prevent motor damage by interrupting excessive current during overload conditions. Typical applications include fans, pumps, conveyors, and other industrial motors where reliable, space-efficient protection and straightforward installation are priorities.
