relationship of make-break operations and tripping current. The two vertices of this characteristic in a double
logarithmic scale are decisive for the setting of addresses 260 to 263:
Point P1 is determined by the number of permitted make-break operations (parameter 261 OP.CYCLES AT
Ir) for rated operational current Ιr (parameter 260 Ir-52)
Point P2 is determined by the maximum number of make-break operations (parameter 263 OP.CYCLES Isc)
for rated fault tripping current Ιsc (parameter 262 Isc-52).
For the procedure to operate correctly, the time response of the circuit breaker must be specified in parame-
ters 266T 52 BREAKTIME and 267T 52 OPENING.
2 t-Procedure
Ι
The Ι t-procedure is activated via configuration parameter 172 52 B.WEAR MONIT. The square fault current
2
integrals are referred to the squared device nominal current. For purposes of determining the arc time, the
device must be informed of the CB tripping time T 52 BREAKTIME as well as the CB opening time T 52
OPENING of the circuit breaker. For recognition of the last zero crossing (arc deletion) of the currents after
tripping, the "Current-zero" Criterion is required.
