UMC100.3
Main Power Lines
Voltage (three-phase systems) Max. 1000 V AC
Attention:
For an U
imp
of 8 kV and a voltage of 1000 V the device must be used according to
Annex H EN60947-1 in the range 600 V < U
e
<= 1000 V.
(IT Network) only for overvoltage category II. Otherwise overvoltage category
III applies.
Grounded networks: For voltages > 690 V isolated wires have to be used.
Ungrounded networks: For voltages > 600 V isolated wires have to be used.
Conductor holes in the current transformers Max. diameter 11 mm incl. cable isolation
Set current range for overload protection UMC alone: 0.24 - 63 A (three phase)
UMC alone: 0.24 - 20 A (single phase)
UMC with provided current transformer: 60 - 850 A
(see chapter 'Connecting External Current Transformers' )
For selecting the correct wire size see "Cross-section of wires"
Overload protection for three-phase and single-phase motors Acc. to EN/IEC 60947-4-1
Trip classes, selectable by parameter
For trip class 40E selecting the contactor and the protective elements
with special care! 5E, 10E, 20E, 30E, 40E (acc. to EN/IEC 60947-4-1)
Tolerance of tripping time (incl. total ranges of current, operational
temperature range, rated frequency) UMC alone: +/- 10 %
UMC with provided current transformer: +/- 14 %
Tolerance of phase imbalance +/- 10 %
Tripping time for phase loss Trip class:
5 approx. 1.5 s
10 approx. 3 s
20 approx. 6 s
30 approx. 9 s
40 approx. 12 s
Accuracy of current measurement
(range 50 to 200 % of I
e
with I
e
> 0.5A)
UMC alone 3%
UMC with provided external
current transformer: 4%
Load per phase: Approx. 30 m
Ω
Frequency range 50 / 60 Hz
Protection of frequency converters is not allowed.
Short-circuit protection Provided by external short-circuit protection device, e. g. MO, MCB, MCCB or
fuse. Refer also to ABB coordination tables available here:
http://applications.it.abb.com/SOC/Page/Selection.aspx
Cross-section of wires Acc. to the rated motor current referring
EN/IEC 60947-1 and the specific installation
condition in EN/IEC 60204 or VDE 298-4 resp.
Vibration according IEC 60068-2-6
Shock according IEC 60068-2-27
