Fox ESS AG-T Three Phase AirGate

The Fox ESS AirGate AG-T is a DIN-rail whole-home backup unit for three-phase Fox ESS hybrid and storage systems. It combines five functions in one device: a circuit breaker (MCB), an on-grid/off-grid changeover switch, energy metering, a bypass switch and current transformers. Rated at 63A, it supports whole-home backup of up to 43.5kW and is designed to cut backup (EPS) wiring and switchboard space.
