Siemens ARGUS 1 Non-Direct O/C Relay 7SG1114-3EA21-0DA0
Siemens ARGUS 1 Non-Direct Overcurrent Protection Relay.
The Siemens ARGUS 1 relay, part number 7SG1114-3EA21-0DA0, is a non-directional overcurrent protection relay. It features a 4-pole relay case size E6 (4U high) and is designed for 110/220V DC auxiliary power. The relay includes 48V binary inputs and has a nominal current rating of 1/5A for its current transformers (CTs).
This relay offers protection elements for phase-fault and earth-fault conditions. It provides flexible I/O configuration with 9 binary inputs and 7 binary outputs (including 3 changeover contacts). Communication capabilities are available via a fiber optic interface (ST-connector) supporting IEC 60870-5-103 or Modbus RTU protocols, enabling integration into modern substation automation systems.
