Typical Application Scenarios

Oil & Gas Upstream & Midstream: Feeder circuits in hazardous-area substations demand zero-compromise protection. The 350-E-P5-G5-H-E-E-N-N-SN-D-N provides ANSI 50/51/50N/51N overcurrent and ground fault protection, minimizing arc flash risk and unplanned downtime in wellhead and pipeline facilities.

✅ Power Plants & Utilities: Utility-grade feeder protection with auto-reclose (ANSI 79) and voltage/frequency supervision (27/59, 81O/U) enables coordinated fault isolation across distribution networks, reducing outage scope and restoration time.

✅ Heavy Manufacturing & Industrial Automation: In automotive, steel, and chemical plants, this relay integrates seamlessly into existing Industrial Automation and PLC System environments via RS485 Modbus RTU or Ethernet IEC 61850, enabling centralized SCADA monitoring without costly rewiring.

✅ Water & Wastewater Treatment: Continuous-process facilities benefit from the relay’s robust EMI immunity and wide operating temperature range (-40°C to +70°C), ensuring stable protection even in chemically aggressive or high-humidity environments.

✅ Renewable Energy & Grid Interconnection: Solar farms and wind installations require precise islanding detection and power quality monitoring. The 350 series relay supports these requirements with built-in metering and configurable protection logic.
