REM601AE446BB1BH

Protection Relay for Distribution Network, 24-265VAC. It is a compact, high-performance numerical relay intended for modern distribution networks. It supports a wide universal supply range of 24–265 V AC or DC and delivers a full suite of protection functions including overcurrent, earth‑fault, negative‑sequence, and thermal overload, enhanced by inrush and cold‑start stabilization. The unit also offers versatile digital I/O, programmable logic, and protocol options (Modbus RTU / IEC 60870‑5‑103, with IEC 61850 or DNP3 in selected variants). With preconfigured settings, USB data export, and selectable sensor interface (CT or Rogowski coil), REF601 simplifies commissioning and maintenance. Coil options include Rogowski for compact MV installations, while safety features like terminal shorting and self‑supervision boost reliability. Overall, this makes REM601AE446BB1BH a flexible, robust, and easy‑to‑deploy solution for feeder protection in utility and industrial distribution applications.
