Overview
The Allen-Bradley 592-EEDC is an electronic solid-state overload relay from the Bulletin 592 series. This E1 Plus model provides dependable thermal-based motor protection by detecting overcurrent conditions and interrupting power before motor damage occurs. When coordinated with proper short-circuit protection, the 592-EEDC safeguards motors, motor controllers, and power wiring against overheating due to excessive currents.
