ELR-CH16 Multi-channel Earth Leakage Relay

Information

Blue Jay ELR-CH16 is a high-integration multi channel earth leakage relay supporting up to 16 independent monitoring channels, engineered for TT and TN-S grounded power systems. This 96×96 panel-mounted unit supports flexible sensor collocation schemes: full 16 leakage CT inputs, 8 leakage + 8 temperature hybrid channels, or 4 leakage + 4 temperature mixed channels. Equipped with a backlit LCD display, it accepts zero-sequence current transformers and temperature probes simultaneously, featuring 20–1000mA adjustable leakage thresholds and 50–120°C temperature alarm limits, perfectly replacing multiple single-channel leakage monitors to simplify cabinet wiring and cut overall project costs. This 16-channel multi channel earth leakage relay provides all-round electrical safety protection by real-time tracking residual current and cable/equipment temperature across all 16 circuits. It triggers visual LED indicators, built-in buzzer and dual relay trip outputs once leakage or overtemperature exceeds preset values, and stores up to 100 timestamped fault records for troubleshooting. Integrated isolated RS485 Modbus-RTU communication enables remote parameter configuration and data upload to SCADA platforms. Widely deployed in EV charging stations, new energy power plants, petrochemical, mining and large commercial distribution systems, it prevents electric shock, cable aging and electrical fires caused by insulation degradation.
