Unbalanced Load-Stage: If set to “Alarm”: The function operates as a supervision function, i.e. a fault generates
neither alarm nor trip, but an »Alarm« signal gets issued instead. If set to “Trip”: The function operates as a
protection function, i.e. trips the breaker in case of a fault.

The Threshold setting denes a minimum operating current magnitude of I2 for the 46 function to operate, which
ensures that the relay has a solid basis for initiating a current unbalance trip. This is a supervisory function and not a
trip level.
