The controller based over load relay (OLR) is
designed to protect three - phase motors, pumps, and industrial equipment from
overload, dry-run, and abnormal current conditions. The unit continuously
monitors motor current and disconnects the load when preset limits are
exceeded.
· Microcontroller-based protection logic
· Accurate current monitoring
· Overload trip protection
· Dry-run detection for pumps
· LED status indication
· Easy current setting button
