Description
The EVR-1P22 is an electronic voltage protection relay from Schneider Electric’s EOCR (Samwha) range, designed to safeguard single-phase electrical systems and equipment from overvoltage and undervoltage conditions. It’s a unified AC/DC design that replaces the older separate EOVR and EUVR model lines, simplifying selection by covering both overvoltage and undervoltage protection — and both AC and DC supplies — in a single reference.
Operating across a wide 100–240V AC/DC supply range, the relay continuously monitors the connected circuit and trips its output contacts the moment voltage moves outside the configured window, protecting downstream equipment from damage. It includes selectable reset modes — manual, electrical, or automatic — giving flexibility in how the system recovers after a fault clears. Two LEDs (green PWR, orange TRIP) provide clear at-a-glance status indication. With a compact footprint (62 × 89.5 × 75mm), DIN-rail or screw mounting, and CUL, CE, CCC, and RoHS certifications, the EVR-1P22 is well suited for protecting single-phase control circuits, instrumentation, and general equipment in industrial, commercial, and marine control panels.
