What is the Earth Fault Relay, and how does it work?
The Earth Fault Relay (EFR 100) detects earth faults in electrical systems and automatically disconnects power to prevent further damage. It provides real-time monitoring and fault detection for enhanced safety.
How is the trip current set on the Earth Fault Relay?
The trip current is programmable, ranging from 30mA to 30A, allowing flexibility for various applications and ensuring appropriate protection.
Can the Earth Fault Relay be used in industrial applications?
Yes, the EFR 100 is ideal for industrial applications, providing protection to machinery, transformers, and control panels in high-power environments.
Does the Earth Fault Relay provide remote monitoring?
Yes, the EFR 100 supports remote monitoring via IoT integration, RS485 MODBUS RTU, and Wi-Fi options, allowing real-time feedback and control.
What is the maximum load that the Earth Fault Relay can handle?
The EFR 100 can handle up to 80A for resistive loads and 50A for inductive loads, making it suitable for a wide range of applications.
