  • Displays the earth-leakage current.

  • Trips the installation protection circuit breaker through an MN or MX voltage release if the earth-leakage current exceeds the alarm threshold >I2 for a time greater than the time delay ton2.

  • Implements two earth-leakage current thresholds, one corresponding to a pre-alarm and another to an alarm.
