Over Voltage  Under Voltage trip release Type Selection

MV: Over Voltage Trip Release (Uvo=270V)

MN: Under Voltage Trip Release (Uoe=170V)

MV+MN: Over and Under Voltage Trip Release  (Uoe=270V Uoe=170V)

MV+MN (Three phase): Over and Under Voltage Trip Release  (Uoe=460V Uoe=300V)

MV+MN (Three phase Four Lines): Over and Under Voltage Trip Release(Uoe=270V Uoe=170V)


Electric MNs Voltage Loss Trip Release : Under Voltage Uoe=170V,Loss Voltage Uoe= 0V (can Switch On MCB When Voltage is 0)

Electromagnetic MNs Voltage Loss Trip Release: Under Voltage Uoe=170V,Loss Voltage Uoe= 0V (cannot Switch On MCB When Voltage is 0)

Electromagnetic MNs Voltage Loss Trip Release (Solar): Under Voltage Uoe=170V,Loss Voltage Uoe= 0V (cannot Switch On MCB When Voltage is 0) With Delay

Electromagnetic MNs Over Voltage/Under Voltage/Voltage Loss Trip Release (Solar): Over Voltage Under Uvo=270V, Voltage Uoe=170V,Loss Voltage Uoe= 0V (cannot Switch On MCB When Voltage is 0) With Delay
