Iso monitoring relay 1-100kOhm - Insulation-/earth fault relay CM-IWS.2P

Iso monitoring relay 1-100kOhm - Insulation-/earth fault relay CM-IWS.2P – ABB – 1SVR740670R0200 – 4016779852654: Iso-monitoring relay 1-100kOhm CM-IWS.2P Design of the electrical connection spring-loaded connection, rated control supply voltage Us at AC 50 Hz 24 ... 240V, rated control supply voltage Us at AC 60 Hz 24 ... 240V, rated control supply voltage Us at DC 24 ... 240V , type of voltage for actuation AC/DC, function for AC networks, rated voltage 0 ... 400V, rated frequency 15 ... 400Hz, system leakage capacitance 10µF, response value impedance 1 1 ... 100kOhm, error storage possible, number of contacts as opener 0, number of Contacts as NO contacts 0, number of contacts as changeover contacts 1, width 22.5mm, height 85.6mm, depth 103.7mm The high reliability of IT systems is ensured by continuous insulation monitoring. Insulation monitoring detects developing insulation faults and reports immediately that the value has fallen below the minimum. This prevents an interruption in operation due to a second, more serious insulation fault. ABB has developed a completely new range of insulation monitoring devices for AC, DC or AC/DC IT systems up to 690 V AC or 1000 V DC. Most standard applications can be operated with only 4 devices. In addition, a version for solar applications with increased discharge capacity has been added.
