Arc Flash & Ground Fault Relay Model AFGF3
The AFGF Relay is a combination Overcurrent/Arc Flash and Ground Fault Relay with Fuse Conservation for switchgear and power distribution systems ranging from 400A–6000A. Designed for electrical equipment protection, not specifically for personnel protection. The Ground Fault section with proper CT/Sensors detects Ground Fault Current in a grounded AC power system.

- Designed for electrical equipment protection, not specifically for personnel protection.
- Arc Reduction section minimizes damage due to overcurrent/arc flash events.
- The Arc Flash/Overcurrent section is not designed to prevent the condition, but to minimize the incident energy release and damage due to current spikes.
- CT/Sensors are sold separately and produced under Electromagnetic Industries Instrument Transformers UL File E238872.
- Use of any other CTs voids the warranty and may result in damage to equipment and the relay.
