The setting method of Huanyu Hi-tech's fee-controlled switch is as follows:
1. The fee-controlled switch is also called a fee-controlled circuit breaker. Its appearance is almost exactly the same as that of the circuit breaker. There are also One control terminal is connected to the electric meter charge control live wire. The electricity bill ran out, the bill control line was out of power, and the circuit breaker tripped.
2. Cost-controlled circuit breaker: The product has a signal line, one end of which is connected to the circuit breaker body and to the internal circuit board of the circuit breaker. One end can be plugged into the dedicated signal output socket of the prepaid electricity meter. When the precharged electricity in the meter is used up, the meter prepayment control module generates a trip control signal of no less than 220V and transmits it to the charge control circuit breaker through the signal line. The circuit breaker detects the source of the signal, analyzes whether the signal is normal or not, and then internally The partial excitation tripper operates, the circuit breaker delays tripping, and then cuts off the power.
