Rated insulation voltage [Ui ]	The following settings are required in order to ensure correct tripping: The fast-response release will take longer to respond when used for DC applications. Because of this, the setting on the trip block inscription, which is specified for AC currents, must be set to a lower value for DC currents. DC correction factor for instantaneous release response value: o NZM1: 1.25 o NZM2: 1.35 o NZM3: 1.45 Example: NZM3 Ie = 500A. Desired DC tripping current: 10 * Ie = 5000A. Calculation: • Desired DC value / correction factor = AC setting on trip block • 5000A / 1.45 = 3448 A ~ 7 * Ie = Value that needs to be set on the trip block Permitted circuit configurations:
