Get a quote
The Samwha EOCR-3EZ is a digital over-current relay designed for comprehensive motor protection and monitoring. It features a current range of 0.5 to 60 A and a clear 7-segment LED display acting as an integrated ammeter. This relay guards industrial equipment against multiple fault conditions by providing adjustable parameters for over-current, under-current, phase loss, phase unbalance, phase reversal, stall, locked rotor, and ground fault protection. It operates on a control voltage of 110 VAC or 220 VAC at 50 to 60 Hz. Built for flexible installation, the EOCR-3EZ supports 35 mm DIN rail or panel flush mounting. Output contacts include a 1-SPST overload contact and a ground fault relay rated at 3A / 250 VAC resistive. It functions reliably in ambient operating temperatures ranging from -20 to 60 degrees C.
