Insulation monitor RN 5897/010 The insulation monitor RN 5897/010 of the VARIMETER IMD family is a solution for optimal insulation monitoring of modern IT systems. The device can be used in the most flexible way for AC, DC and AC/DC systems even with large leakage capacity to earth (PE). The adjustment of the setting values is simple and user friendly done on 2 rotary switches on the front of the device. Via display and LEDs the measured value, device parameters and device status are indicated easy to read. With a sealable transparent cover the device is protectet against manipulation. Advantages . Preventive fire and system protection . Detection of symmetric and asymmetric insulation faults . Quick fault localisation through selective earth fault detection to L+ and L- . Universal application in non-earthed AC, DC, AC/DC networks up to AC max. 250 V or DC max. 300 V . With connection facility of an external coupling device: RL 5898 for voltages up to AC 400 V / DC 500 V RP 5898 for voltages up to AC 690 V / DC 1000 V RR 5898*) for voltages up to AC 1000 V / DC 1500 V .
