Description
The EOCRSS‑60S is a compact electronic protection relay engineered for overcurrent monitoring and motor protection in both single‑phase and three‑phase systems. Unlike traditional thermal overload relays, this EOCR uses electronic sensing to measure the actual current and trip rapidly when fault conditions occur, improving safety and reducing equipment damage.
This device typically supports an adjustable current range of 5 A to 60 A, allowing users to set the threshold according to motor or load requirements. It also provides adjustable operating time delay to prevent nuisance tripping during normal motor startups. The relay detects several fault conditions including overcurrent/overload, phase loss, locked rotor (when current is significantly higher than normal), and phase unbalance.
The unit includes LED indicators for real‑time status, fault display, and operational feedback, and it integrates easily into control systems with screw terminal connections and DIN‑rail mounting. Reset options often include manual or remote reset, giving flexibility depending on the application.
It is widely used in industrial motor control panels, pumps, compressors, conveyors, HVAC systems, and other industrial automation applications where motor protection and reliable current monitoring are crucial.
