This product supports the use of a three-phase circuit breaker and three independent single-phase circuit breakers (1p/2p), with a rated current of 80A per phase. If single-phase circuit breakers are required, please enable the separate phase mode in the Tuya APP using the "Separate e.." switch. The "Separate e.." switch controls whether the three relays are separated. When "Separate e.." is open, it provides three independent single-phase over/under voltage protection. When "Separate e.." is closed, it operates in combined mode.
