5.6.2. LIMIT VALUE EXPLANATION
There are five possibilities to select the limit prospective short-circuit current I
SC LIM
, which is the bases
for final evaluation.
STD
- no verification.
No limit is used in this case meaning test result is not evaluated and is therefore always considered as
neutral (displayed in white colour).
kA
- verification if short-circuit current is lover than breaking capacity of involved over-current protection
device.
Measured I
SC MAX
must be lower or equal than entered breaking capacity Ib of involved over-current
protection device, where breaking capacity Ib can be selected among the following values:
-
Ib (breaking capacity)
1, 1.5, 3, 4.5, 6, 10, 15, 16, 20 or 25 kA
I
2
t
- verification if over-current protection device reacts before wires are overheated and thus damaged.
On bases of measured I
SC MAX
and entered over-current protection device (PROTECTION) and
nominal current of the over-current protection device (In) trip out time of the over-current protection
device (t) is calculated. See the evaluation equation in the table “PROSPECTIVE SHORT-CIRCUIT
CURRENT CALCULATION” below. Entered parameters can be selected among the following values:
-
PROT (type of protection)
MCB B, MCB C, MCB D, MCB K, FUSE gG or FUSE aM

TRIP CURRENT
- verification if over-current protection device reacts within set time at measured short-
circuit current.
On bases of measured I
SC MIN
and entered over-current protection device (PROTECTION) and nominal
current of the over-current protection device (In) trip out time is calculated which must be lower than or
equal to entered Tset. Entered parameters can be selected among the following values:
