Star-delta starting of three-phase asynchronous motors
Contactor selection
General
Star-delta starting is the most common method to reduce the starting current of a motor. This system can be used on all the
squirrel cage motors, which are normally used in delta connection.
In this type of starting, it is recommended to choose motors having high starting torque i.e. much higher than the resistive
torque in order to reach sufficient high speed when the motor is connected in star.
Star-delta starting
3
I
/In T
/Tn Technical Data
7 When starting:
I = current; In = nominal current –– inrush current is reduced to a third of direct starting current
T = torque; Tn = nominal torque –– motor torque is reduced to a third or even less of direct
6
starting torque.
I (delta)
Transient current is generated when switching from star to delta con-
5
nection.
Utilization
4 During the initial starting phase ("star" connection), the resistive torque
of the driven load must remain, irrespective of speed, less than the
"star" motor torque until "star-delta" switching occurs.
3 This starting mode is therefore ideal for machines having low starting
torque such as:
T ( m ot –– pumps
2 or
) –– centrifugal compressors
I (sta
r) –– wood-working machines, etc.
1 In order to prevent a high current peak, at least 85 % of nominal
T (motor) speed must be reached before switching from star to delta.
Tr (resistive torque)
Precautions
0 20 40 60 80 100 Motor nominal voltage in delta connection must be equal to that of the
Motor speed (%) mains.
Example:
A motor for 400 V star-delta starting must be designed for 400 V in "delta" connection. Its usual designation is "400 V / 690 V
motor". The motor must be constructed with 6 terminal windings.
Sequence
Starting is a three-stage process:
1st stage - "Star" connection
Press the "On" button on the control circuit to close the KM2 "star" contactor. The KM1 "line" contactor then closes and the
motor starts. Countdown of programmed starting time (normally 6 to 10 s) then begins.
2nd stage - "Star" to "Delta" switching
When the programmed starting time is over, the KM2 "star" contactor opens.
3rd stage - "Delta" connection
A transition time (or dwelling time) of 50 ms is fixed between opening of the "star" contactor and closing of the "delta" contac-
tor by the use of TE5S timer. This prevents short circuit between "star" and "delta".
Note: An electrical interlock between star and delta is mandatory such as VE 5 or through auxiliary contacts.
Furthermore, in open transition, the current interruption may reach up to 95 ms: it shall be checked that this duration is compatible with the application i.e. mainly if the decreasing
in rotation speed is acceptable during the starting phase.

Electronic timer for star-delta starters
Description
When used in star-delta starters, the TE5S lags the star connection and provides a lapse of 50 ms before
the switch over to delta connection.
According to the type of device chosen, the electronic circuit has a 24 V AC / DC, 110 to 120 V AC,
1SBC575582F0302
220 to 240 V AC or 380 to 440 V AC supply. An output relay with reversing contact ensures high current
switching. A two-position switch allows selection of one of the two time delay ranges: 0.8 to 8 s or 6 to
60 s. The 0.1 to 1.0 graduated button allows an initial setting without steps within the previously selected
range which can then be adjusted using a chronometer.
3 Note: We recommend that you allow for temperature drift for the final adjustment of the time delay setting.
Drift: -0.2 % per °C.
TE5S...
For example, a setting made at 20 °C will yield a time delay shorter by 7 % at 55 °C in a c ubicle (-0.2 %
per °C i.e. -0.2 x 35 = -7 %).
Regardless of these settings the TE5S provides a fixed "lapse" of 50 ms between the opening of contact
15-16 and the closing of contact 15-18. This time delay prevents from arc short-circuit during star to delta
switching.
Operation
On energization, the green U indicator light (voltage applied) comes on. Contact 15-16 then immediately
U
moves to the closed position.
15-16 Count-down of the programmed time immediately commences. When the time delay has elapsed, contact
15-16 opens and at the same time the 50 ms lapse, t2, begins after which contact 15-18 moves to the
E0719D1
R
15-18 closed position. The yellow R indicator light comes on.
t1 t2 (t2 = 50ms) On de-energization, the U and R indicator lights go out and, after the 250 ms resetting time, the device is
ready for a new cycle.

Surge suppressors for contactor coils
(V) Description
1000
The operation of inductive circuits causes overvoltages, in particular on opening of the contactor coil.
T (µs)
0 100 The electromagnetic energy stored in the coil during contactor closing is restored on opening in the form of
1000 surges, the slope and amplitude of which may rise to several kilovolts. A number of drawbacks are observed
ranging from interference on the electronic devices to breakdown of insulators and even destruction of cer-
0 100
tain sensitive components.
The graph opposite reproduces the oscillogram showing voltage discharges at the terminals of a 42 V /
A 884D
50 Hz coil without peak clipping. The coil was switched by 8 series-connected poles of a contactor relay.
3 Following a burst of discharges with a very steep slope a damped oscillation emerges with a peak value of
3500 V.
Overvoltage Factor
The overvoltage factor k is defined as the ratio of the maximum overvoltage peak value Ûs to the peak value
Ûc of the coil rated control voltage Uc:
Ûs max. Ûs max. Ûs max.
1SBC574001F0301
k = in DC: k = or in AC: k =
Ûc Uc Uc√2
3500
RV5/50 For example the following is obtained for the above graph: k = ≈ 60
42 √2
To reduce the harmful effects of these overvoltages, ABB has developed a range of surge suppressors de-
signed to reduce the k factor defined above and to limit or even completely eliminate the high pre-damping
voltage frequencies.
Each case is different, but the technical data tolerances and the generous sizing of parts have enabled us to
reduce the number of variants.
We have chosen the following solutions: transil diodes, varistors and RC blocks.
1SBC573891F0301
Note: A varistor is a resistor whose value decreases to a very large extent when a certain voltage is applied
at its terminals.

Interface relays
Description
1SBC101005F0014
RA5-1 interface relay is designed to receive 24 V DC signals delivered by PLC’s or other sources with a
low output power and to restore them with sufficient power to operate the coils of the relevant A9 ... A110
contactors.
RA5-1 interface relay is made up of a miniature electromechanical relay equipped with a N.O. contact and
with a low consumption 24 V DC coil.
The interface relay coil is controlled by the PLC while the N.O. contact ensures switching of the power contactor.
RA5-1
3 Coil switching gives rise to overvoltages which have adverse effects on the electronic devices, insulators and,
more generally, on component lifetime. The RA5-1 is equipped with surge suppressors:
–– on the 24 V DC relay coil via a diode,
–– on the power contactor coil via a varistor.
Furthermore, the RA5-1 is protected against relay pole reversal by a diode inserted between the E1 and E2
input terminals.
