Description click to view larger image 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. Specifications: Input Power Options: 120 Vac Frequency: 50/60 Hz Ground Fault: Trip currents ranges available: 100-1200A, 200-1200A and 300-1200A Input Withstand: 200,000 Amperes RMS for 3 cycles, 50/60 Hz. Ambient Temperature Range: -30 Deg C. to 60 Deg C. Contact Ratings: Normally open, Dry Type, 120Vac, 5A (Make and Carry 0.2 sec, 30A) Order corresponding CT separately. See datasheet for dimensions.
