Protect small to medium motors with the EOCR‑SS Electronic Over Load Relay (0.5–6.5A). The wide adjustable range (0.5–6.5A) covers many fractional‑HP and compact three‑phase motors, making it perfect for OEM panels and maintenance retrofits.
The EOCR‑SS offers accurate electronic protection with adjustable trip time, start delay, and selectable auto/manual reset. It typically detects phase loss and unbalance to guard against wiring faults and supply issues. Clear LEDs show RUN/TRIP status, and front dials make setup fast and repeatable. Use the relay output (C/O) to interrupt the contactor coil for safe, reliable shutdowns.
