KRM162x Series![]() Brand: Megacon
Model: KRM162x - Earth Leakage AC Trip Relay
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. Relay is fail-safe and energises when powered. Link terminal 6 and 10 to make a non-latching relay. All current carrying conductors must pass through the core balance CT. Metal sheaths or braiding on any cables must NOT be passed through the CBCT. |
