ABB LIMITED 2/12

AF 50 ... AF 750 3-pole Contactors

a.c. / d.c. Operated - Large Voltage Range

Electronic Coil Interface

Control circuit with

electronic coil interface.

Control inputs (AF

400 ... AF 750)

Application

AF 50 ... AF 750 contactors are mainly used for controlling 3-phase motors and generally for controlling power circuits up to 690 V a.c. or

220 V d.c. / 600 V d.c. The contactors can also be used for many other applications such as bypass, capacitor switching, lighting, d.c. power

circuits...

The AF... contactors are fitted with an electronic coil interface which accepts a wide control voltage range, on a.c. 50/60 Hz or d.c. supplies.

The same contactor can accept various supply voltages according to different countries where the final machine will be used or some

fluctuation in the control voltage due to the local supply or network.

The AF... contactors are also fully suitable for operation in a.c. or d.c. control circuit liable to voltage interruptions or voltage dip risks.

Description

The AF 50 ... AF 750 3-pole contactors are of the block type design.

• Main poles and auxiliary contact blocks

– 3 main poles,

-AF50 ... AF110 front and side mounted add on auxiliary contact blocks

–AF145 ... AF750 1 N.O. and 1 N.C. auxiliary contact block (fitted on the left side).

A maximum of 4 auxiliary contact blocks can be fitted on each contactor.

• Electronic control:

The contactors are fitted with an electronic interface that very precisely controls the voltage to the coil. The electronic control circuit always

works using d.c. current through the coil and in a.c. operation the current is rectified before being applied to the coil. To achieve the levels of

the currents required for making and holding respectively, the voltage is pulsed across the coil with the aid of a transistor. The pulsing also

implies that the current in the coil can be optimally regulated all the time relatively independently of the voltage level. The function is controlled

by a specific integrated circuit developed by ABB.

• Advantages

–Wide voltage range, e.g. 100 ... 250 V a.c. and d.c.,

– Can manage large voltage variations,

– Reduced power consumption,

– Very distinct closing and opening,

– Noise free,

–Can withstand voltage interruptions or voltage dips in the control supply (< 20 ms).

• Control inputs

The large sizes AF 400 ... AF 750 are as standard equipped with low voltage inputs for control, for example by a PLC (+ see drawing below).

•Accessories: a wide range of accessories is available.

Star-Delta Starting

of Three-Phase Asynchronous Motors

General

When starting, the motor has to overcome the load torque and inertia of the driven machine. During this phase, current must

remain within the limits acceptable by the mains.

Inertia, load torque and mains are commonly fixed data.

Although the type of starting reduces the inrush current as required, it also reduces the torque supplied by the motor. The result is a starting

time that varies according to the starting process used.

Star-delta starting

Technical Data

When starting:

– inrush current is reduced to a third of direct starting current,

– motor torque is reduced to a third or even less of direct starting

torque.

Transient currents are commonly read during star-delta switching.

Utilization

During the initial starting phase ("star" connection), the resistive torque

of the driven machine must remain, irrespective of speed, less than the

"star" motor torque until "star-delta" switching occurs.

This starting mode is therefore ideal for machines with no-load starting:

– machine-tools,

– centrifugal compressors,

– wood working machines, etc.

In order to prevent a high current peak, at least 80 - 85 % of

nominal speed must be reached before switching from star to

delta.

Precautions

Motor nominal voltage in delta connection must be equal to that of the

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" contactor by the use of

TE5S timer. This prevents short circuit between "star" and "delta".

Note: When AF... contactor types are used as delta and star contactors or an A... contactor as star contactor with an AF... contactor as delta contactor, the use of a timer including a

dwelling time (or transition time) e.g. TE5S or similar is not necessary. A timer set for the starting duration in star connection is enough. 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.

Contactors for Capacitor Switching

AC-6b Utilization Category according to IEC 60947-4-1

Capacitor Transient Conditions

In Low Voltage industrial installations, capacitors are mainly used for reactive energy correction (raising the power factor). When these

capacitors are energized, overcurrents of high amplitude and high frequencies (3 to 15 kHz) occur during the transient period (1 to 2 ms).

The amplitude of these current peaks, also known as "inrush current peaks", depends on the following factors:

• The network inductances.

•The transformer power and short-circuit voltage.

•The type of power factor correction.

There are 2 types of power factor correction: fixed or automatic.

Fixed power factor correction consists of inserting, in parallel on

the network, a capacitor bank whose total power is provided by

the assembly of capacitors of identical or different ratings.

The bank is energized by a contactor that simultaneously

supplies all the capacitors (a single step).

The inrush current peak, in the case of fixed correction, can

reach 30 times the nominal current of the capacitor bank.

Fixed power factor correction

An automatic power factor correction system, on the other hand,

consists of several capacitor banks of identical or different ratings

(several steps), energized separately according to the value of the

power factor to be corrected.

An electronic device automatically determines the power of the

steps to be energized and activates the relevant contactors.

The inrush current peak, in the case of automatic correction,

depends on the power of the steps already on duty, and can

reach 100 times the nominal current of the step to be energized.

Automatic power factor correction

Steady State Condition Data

The presence of harmonics and the network's voltage tolerance lead to a current, estimated to be 1.3 times the nominal current Inof the

capacitor, permanently circulating in the circuit.

Taking into account the manufacturing tolerances, the exact power of a capacitor can reach 1.15 times its nominal power.

Standard IEC 831-1 Edition 04/97 specifies that the capacitor must therefore have a maximum thermal current ITof:

IT= 1.3 x 1.15 x In= 1.5 x In

Consequences for the Contactors

To avoid malfunctions (welding of main poles, abnormal temperature rise, etc.), contactors for capacitor bank switching must be sized to

withstand:

•A permanent current that can reach 1.5 times the nominal current of the capacitor bank.

•The short but high peak current on pole closing (maximum permissible peak current Î ).

ABB offers 3 contactor versions according to the value of the inrush current peak and the

power of the capacitor bank
