ABB AF63-30-00 100-250V 50Hz AC/DC Contactor 65A 30kW 1SBL377001R7000

ABB AF63-30-00 Product Overview

ABB AF63-30-00 is designed as a three-pole contactor for switching and controlling
electrical loads in industrial installations. Its AF technology replaces the
conventional wide range of individual AC coil variants with electronically controlled
coil technology. ABB states that the AF contactor platform uses a broad control-voltage
range to cover standard network voltages, helping simplify product selection and system
configuration.

The AF63 designation identifies the contactor size, while the 30-00 configuration
describes the main contact arrangement and auxiliary-contact configuration. The
contactor has three main poles and is supplied without built-in auxiliary contacts.
Additional auxiliary contact accessories can be incorporated when the electrical control
circuit requires feedback, interlocking, signaling, or sequencing functions.

The complete product number, 1SBL377001R7000, is an important identification reference.
ABB offers AF contactors with different contact arrangements, control-voltage ranges,
connection configurations, and accessories. Using the complete product number helps
distinguish the AF63-30-00 100-250V version from related AF63 variants.

100-250V AC/DC Electronic Coil

One of the defining characteristics of the ABB AF63-30-00 is its electronically
controlled coil. The specified control-voltage range is 100–250 V for AC operation
at 50/60 Hz and also 100–250 V DC. This design provides a considerably wider operating
range than a traditional contactor with a fixed single-frequency coil.

The electronic control system rectifies the AC or DC control voltage and applies an
appropriate DC voltage to the operating coil. This architecture allows the same
contactor configuration to accommodate different control supply conditions within the
specified range. It is particularly useful for industrial systems where control
voltages can vary between equipment installations.

ABB also identifies integrated surge suppression as one of the characteristics of AF
contactors. The electronic coil design contributes to controlled operation and reduced
coil energy consumption compared with conventional contactor technologies. ABB states
that AF technology can reduce coil energy consumption by up to 80 percent, depending on
the applicable operating conditions.

65A AC-3 Rating and Motor Applications

The AF63-30-00 is rated at 65 A for AC-3 operation at 400 V. AC-3 is the utilization
category commonly associated with squirrel-cage motor starting and switching. Under
this category, the contactor is designed to handle the electrical conditions associated
with starting a motor and interrupting the motor current during normal operation.

At 400 V, the AF63 contactor corresponds to a motor power rating of up to 30 kW under
the applicable AC-3 conditions. The actual suitability of the contactor depends on the
motor characteristics, operating voltage, load behavior, starting method, switching
frequency, ambient conditions, and applicable electrical standards.

The 65 A value should therefore not be interpreted as a universal load rating for every
possible application. Different utilization categories have different electrical
requirements. Engineers should select the contactor according to the actual load type
and application conditions rather than relying only on the nominal current value.

Technical Specifications

Main Contact Configuration

The ABB AF63-30-00 incorporates three main normally open contacts. These three poles are
used to establish or interrupt the three-phase power circuit when the contactor is
energized or de-energized. The arrangement is suitable for three-phase electrical loads
and is commonly used in motor control circuits.

The -00 configuration does not include built-in auxiliary contacts. This provides a
straightforward three-pole main-contact arrangement for applications where additional
auxiliary switching is not required as part of the standard contactor configuration.

When auxiliary signaling or control functions are needed, compatible ABB auxiliary
contact blocks can be selected according to the system design. These accessories can
provide additional normally open or normally closed contacts for electrical control,
indication, interlocking, and sequencing.

AF Technology and Voltage Flexibility

ABB AF contactors are distinguished by their electronically controlled coil system.
Instead of requiring a separate contactor coil for every conventional control voltage,
the AF platform uses a wider voltage range. For the AF63-30-00, the 100–250 V range
covers both AC and DC control applications within the specified operating limits.

This approach can simplify electrical system design where different installations use
different control-voltage standards. A single AF contactor configuration can be applied
across a broader range of control environments, provided the control voltage remains
within the specified limits.

The electronic coil also helps the contactor maintain operation across certain voltage
disturbances. ABB identifies AF technology as capable of bridging voltage drops and
sags, supporting reliable contactor operation in industrial electrical networks.

Industrial Motor Control

The ABB AF63-30-00 can be used in industrial motor-control systems where a three-phase
contactor with a broad AC/DC control-voltage range is required. Typical system
architectures can include motor starters, control panels, machinery, pumps, fans,
compressors, conveyors, and other electrically driven equipment.

In a conventional motor starter, the contactor provides the main switching function,
while an overload relay or electronic motor protection device can provide protection
against overload conditions. The contactor and protection components are selected
according to the motor’s rated current, voltage, power, starting characteristics, and
required protection strategy.

For a 400 V motor application under AC-3 conditions, the AF63-30-00 is associated with
a 30 kW motor rating. However, the final selection should consider the actual motor
nameplate information and the requirements of the complete starter or control system.

Electrical System Integration

Proper integration of the AF63-30-00 requires separate consideration of the main circuit
and the control circuit. The main three-phase circuit carries the controlled load, while
the electronic coil receives the specified 100–250 V AC/DC control signal.

Because the coil accepts both AC and DC within the specified range, the control system
can be designed around either type of supply. Nevertheless, the control voltage must
remain within the manufacturer’s specified operating range and must be connected
according to the applicable ABB wiring instructions.

The installation should also account for conductor sizing, terminal arrangement, cabinet
space, environmental conditions, thermal requirements, short-circuit coordination, and
the characteristics of the connected load. These factors determine the complete electrical
performance of the contactor installation.

Product Identification and Selection

Accurate identification is important because ABB provides multiple AF63 contactor
configurations. The AF63-30-00 100–250 V version is identified by ABB product number
1SBL377001R7000. Related products can have different coil voltage ranges or auxiliary
contact arrangements while retaining a similar basic product designation.

The distinction between AF63-30-00 and AF63-30-11 is especially important. The -00
configuration has no built-in auxiliary contacts, whereas the -11 configuration includes
an auxiliary contact arrangement. Checking the complete product designation prevents
confusion when preparing electrical documentation or selecting a corresponding component.

Conclusion

ABB AF63-30-00 100-250V is a three-pole AF series contactor identified by ABB product
number 1SBL377001R7000. Its electronic coil accepts 100–250 V AC at 50/60 Hz as well as
100–250 V DC, providing a broad control-voltage range for industrial electrical systems.

At 400 V under AC-3 conditions, the AF63-30-00 provides a 65 A rated operational current
and is associated with motor applications up to 30 kW. The main contact configuration
consists of three normally open poles, while the standard -00 version has no built-in
auxiliary contacts.

The combination of electronic coil technology, broad AC/DC control capability, three-pole
switching, and industrial motor-control characteristics makes the ABB AF63-30-00 a
versatile component for compatible electrical control systems. Correct selection should
always consider the motor or load characteristics, utilization category, operating voltage,
control voltage, environmental conditions, and the requirements of the complete electrical
installation.
