7SR4501-1GA10-1AA0/FF SIEMENS - REF

The 7SR4501-1GA10-1AA0/FF is a robust and reliable ARGUS non-directional overcurrent-time protection relay from Siemens, designed to safeguard electrical systems from overcurrent faults. Housed in a durable polycarbonate enclosure, it offers a compact and resilient solution for various protection applications. This relay utilizes four current transformer inputs to accurately measure current levels and detect overcurrent conditions. It features two binary inputs and two binary outputs, providing flexibility for control and signaling purposes. A pulse output is included for energy metering or other applications requiring pulse signals. The device incorporates nine LEDs for clear indication of relay status and fault conditions. The measuring input is configured for 1A, 50/60 Hz systems, and the relay is self-powered via the current transformer, eliminating the need for an external auxiliary voltage supply. A USB front interface allows for easy configuration and data retrieval. This particular model does not include any communication protocols or rear interface options and comes with a basic protection function package.
