Arc Flash / Overcurrent / Ground Fault Relays – Electromagnetic Industries
Description
The AFGF Relay is a combination Arc Flash, Overcurrent and Ground Fault Relay (with fuse conservation) for switchgear and power distribution systems ranging from 400A to 6000A.
Arc Flash & Overcurrent Relay Section: The Arc Flash/Overcurrent section is designed to minimize damage due to overcurrent & arc flash events. It features Inverse Time Delay to provide overcurrent and fuse protection while minimizing nuisance trips due to inrush and transients.
Ground Fault Section: These Class 1 Ground Fault relays with the proper CT/Sensors, are used for detecting Ground Fault Current in a grounded AC power system.
• Meets NEC service entrance equipment standards.
• Power Indication
• Maintenance Mode Select Switch (w/ connections for a remote switch)
• Maintenance Mode Indication
• Test Selection (Select Push to Test between Ground Fault and Overcurrent)
• Separate Ground Fault and Overcurrent trip contacts
• Operates with molded case power circuit breakers, bolted pressure switches, or fusible disconnect switches.
Note: The AFGF system is designed for electrical equipment protection, not specifically for personnel protection.
