Table 329: HAEFPTOC Technical data
Characteristic Value
Operation accuracy Depending on the frequency of the current
measured: fn ±2 Hz
±5 % of the set value or ±0.004 x In
Start time
1)2)
Typical 77 ms
Reset time < 40 ms
Reset ratio Typical 0.96
Operate time accuracy in definite time mode ±1.0% of the set value or ±20 ms
Operate time accuracy in IDMT mode
3)
±5.0% of the set value or ±20 ms
Suppression of harmonics -50dB at f= fn
-3dB at f= 13 x fn
1) Fundamental frequency current = 1.0 x In. Harmonics current before fault = 0.0 x In, harmonics fault
current 2.0 x Start value. Results based on statistical distribution of 1000 measurement.
2) Includes the delay of the signal output contact
3) Maximum Start value = 2.5 x In, Start value multiples in range of 2 to 20
