The KRM162B measures the insulation, directly in milliamps, of earthed AC systems. But it can also be used in IT-systems together with a constant impedance module type MML1501. The instrument is fed from a suitable Core Balance current transformer (CBCT see separate datasheet) Standard relay has a 0-150mA range with a factory set trip level of 100mA. Larger ranges and trip levels are available, typically ranges is 500mA, 0-1A, 0-2A, 0-5A and 0-10A. Special features: -Earth leakage relay for earthed AC systems -Non isolated analogue output (C-version) -"RCT" measuring principle Borna niroo karan company (Brnika) is Exclusive Representative of Megacon , in the purchase, sales, consulting and distribution and industrial equipment and measurement equipment, including earth fault monitoring is active .
