3. Technical parameters of overvoltage, undervoltage, overundervoltage and undervoltage trip units

 

Attachment Name	Rated control power supply Voltage Ue	Trip voltage	Function
Overvoltage trip unit MV(iMSU)	AC230V	Overvoltage value :270V±5%	When the power supply voltage rises to 270V±5%, the circuit breaker is tripped to achieve overvoltage protection for the circuit.
Under-voltage trip unit MN(iMN)	AC230V	Under-voltage value :<160V±5%	When the power supply voltage drops below 160V, the circuit breaker is tripped to achieve undervoltage protection for the circuit.
Overvoltage and undervoltage trip unit MV+M N(iMNV)	AC230V	Overvoltage value :270V±5% Under-voltage value :<160V±5%	When the power supply voltage rises to 270V±5% or drops below 160V, the circuit breaker is tripped to achieve line protection.
Three-phase overvoltage and undervoltage + phase loss MV+MN (iMNV)	AC380V	Overvoltage value :460V±15V Under-voltage value :300V±15V	When the power supply voltage rises to 460V±15V or drops below 300V±15V, the circuit breaker is tripped to achieve line protection.
Three-phase four-wire overvoltage and undervoltage MV+MN(iMNV)	AC230V	Overvoltage value :270V±5V Undervoltage value:<160V±5%	When the power supply voltage rises to 270V±5V or drops below 160V±5V, the circuit breaker trips to achieve line protection.
Electronic undervoltage trip unit MNS (iMNS)	AC230V	Under-voltage value :170V±5% Undervoltage value :0 tripping	When the power supply voltage drops to 170V±5% or there is no electricity, the circuit breaker trips to achieve undervoltage protection of the line (the circuit can be closed during power failure).
Electromagnetic undervoltage trip unit MNS (iMNS)	AC230V	Under-voltage value :35% to 75% Undervoltage value :0 tripping	When the power supply voltage drops to 35% to 75% or there is no electricity, the circuit breaker trips to achieve undervoltage protection of the line (the circuit cannot be closed during a power outage).
Electromagnetic undervoltage trip unit MNS (iMNS)(For photovoltaic use)	AC230V	Under-voltage value :35% to 75% Undervoltage value :0 trip (with delay)	When the power supply voltage drops to 35% to 75% or there is no electricity, the circuit breaker (delayed) trips to achieve undervoltage protection of the line (the circuit cannot be closed during power failure).
Electromagnetic overvoltage and undervoltage tripping Instrument MNVS(iMNVS (For photovoltaic use)	AC230V	Overvoltage value :270V±5% Under-voltage value :35% to 75% Undervoltage value :0 trip (with delay)	When the power supply voltage rises to 270V±5V or drops to 35% - 75% or there is no electricity, the circuit breaker (delayed) trips to achieve overvoltage and undervoltage undervoltage protection of the line (the circuit cannot be closed during power failure).
