Undervoltage trip RM-250/400 ( RM-35/37 )

Descriere

RM undervoltage trip provokes MCCB shutting down when phase or line voltage at the input is lowered up to 70% from the rated value. It also helps to prevent MCCB actuation is the circuit voltage is less than 85% from the rated values. High speed operation and guaranteed instantaneous switch off when phase or line voltage is reduced. Compliance with current breakers: IEK_V0000043 Seal-in voltage range: (0,7-1,1)Ue Nominal rated voltage: 230 Mains frequency: 50 Range of actuation voltage: (0,85…
