Remote operation: (1600AF/4000AF on the left, 2000AF/2500AF/3200AF/6300AF on the
right)
Release MX:
After the circuit breaker is stored with energy, the shunt coil can disconnect the
circuit breaker instantaneously under the specified power supply voltage, which
can be operated remotely
Rated control power supply voltage AC220 / AC230V / AC380V / AC400V /
DC110V / DC220V
Action voltage (0.7-1.1) us
breaking time:50±10ms
Closing coil XF:
After the circuit breaker is stored with energy, the closing coil can close the
circuit breaker under the specified power supply voltage, which can be operated
remotely
Rated control power supply voltage AC220 / AC230V / AC380V / AC400V /
DC110V / DC220V
Action voltage(0.85-1.1)Us
closing time:55±10ms
Undervoltage release MN:
Undervoltage coil can be divided into two types: undervoltage instantaneous
and undervoltage delay
After the circuit breaker is closed, when the voltage of the circuit breaker drops
to 70% - 35% of the rated voltage, it can act to make the circuit breaker open.
The circuit breaker can only be closed again after the supply voltage of the
undervoltage coil recovers to 85% of the rated voltage
Rated control power supply voltage AC220 / AC230V / AC380V / AC400V
Action voltage:(0.35-0.7)Ue
Reliable closing voltage:(0.85-1.1)Ue
no closing voltage:≤0.35Ue
delay time: 0.5s, 1s, 1.5s, 3S after disconnection (1600AF/4000AF support)
delay time: 1s, 3S, 5S after disconnection (2000AF/2500AF/3200AF/6300AF
support)
The maximum delay time is 7.5S, which can be set according to the actual
situation
Undervoltage delay coil MNR:
延时时间:0.5s、1s、1.5s、3s 后断开(1600AF/4000AF 支持)
延时时间:1s、3s、5s 后断开(2000AF/2500AF/3200AF/6300AF 支持)
Motor operating mechanism MCH:
The motor operating mechanism can automatically store energy to the circuit
breaker when the circuit breaker is disconnected and provided with power
supply, so as to open or close the circuit breaker under the action of shunt coil,
undervoltage coil and closing coil
When there is no power supply, the manual handle can be used to store energy
for the circuit breaker
