The Bender IRDH 250 MYX is an insulation monitoring device from Bender, designed specifically for unearthed systems (IT systems). It continuously monitors the insulation resistance of three-phase AC main circuits and issues an alarm signal when the insulation value falls below a preset threshold, ensuring the continuity and safety of the power supply.
