Key Features and Engineering Advantages
Comprehensive Protection Suite:Integrated logic to protect against thermal overload, three-phase overcurrent, and sensitive earth faults, ensuring the safety of feeder cables and connected equipment.
Plug-in Construction:The "draw-out" design simplifies commissioning and maintenance, as the relay can be replaced or tested without rewiring the terminal blocks.
Advanced Communication:Native support for multiple protocols allows the relay to act as a data node for SCADA systems, providing remote access to metering and fault records.
High-Accuracy Metering:Real-time monitoring of phase currents and neutral current provides essential data for load management and system diagnostics.
Industrial Durability:With an operating range down to -40°C, this relay is built to perform in extreme environments, from arctic utilities to offshore marine vessels.
Sequence of Events (SOE):Records fault data and event logs internally, facilitating rapid forensic analysis after a trip occurs.
