Maximum DC 1500V / AC 1100V, supports system leakage capacitance up to 3000μF! Insulation monitoring for ungrounded circuits.
The ABB insulation monitoring relay for non-earthed circuits (CM-IWx series) monitors insulation degradation and immediately issues a warning when it falls below a set minimum threshold. This enhances system reliability and reduces downtime. It supports up to DC 1500V and AC 1100V. Additionally, thanks to its unique measurement technology, it considers system leakage capacitance of up to 3000μF. By using ABB's insulation monitoring relay, insulation monitoring becomes safer and maintenance smarter. 【Features】 ■ Prevents fires by detecting the aging degradation of insulation resistance ■ Easy adjustment of set values using the rotary switch located on the front of the device ■ Device status is displayed with easy-to-read and understand LEDs ■ Variants approved for railways and ships are available *For more details, please refer to the PDF document or feel free to contact us.
