Protect your motors with the EOCR‑SS Electronic Overload Relay (5–70A). This smart motor protector continuously monitors current and trips your contactor before damage occurs—ideal for pumps, compressors, conveyors, fans, and general machinery. With a wide adjustable range (5–70A), it fits many motor sizes, making it perfect for maintenance teams and OEMs.
The EOCR‑SS provides stable electronic overload protection with adjustable trip time, start delay, and manual/auto reset options. Many models also detect phase loss and unbalance to protect three‑phase motors from wiring faults and low‑voltage issues. Clear LEDs show run and trip status, while front dials make setup quick and repeatable. Use the relay output to open your contactor coil for safe, reliable shutdowns.
