Description
Product details
The N22-EFR/d senses total current passing from the DC system on Positive or Negative BUS & calculate leakage current passing through earth if any. The relay operates when the leakage current goes above the range selected on dial provided on front. It has Fault level setting from 1% to 10% of rated current sensor, for e.g. for Sensor A (25A) it shall be=250mA-2.5A with resolution in 10 steps. It also has time delay setting from 1 to 10 sec for delay in relay operation after fault occurs. The relay has one change over set of contacts.
