Value
Depending on the frequency of the measured current: f
Differential voltage U = ±0.5% of the measured value or ±0.005 × U
d
measured voltages <2.0 × U )
n
Operation value = ±1.5% of the U

(at theoretical B in range of 1.1...5.0)
Also note fixed minimum operate time (IDMT) 1 s
Typically 0.80 (1.20)
Typically 0.96 (1.04)
