Product Overview

The ABB 1SBL143061R5510 combines the TAL9-30-10 contactor design
with a specific DC coil configuration. The TAL9-30-10 designation
identifies a three-main-pole contactor with one normally open
auxiliary contact. The R5510 ordering-code configuration identifies
the 50-90 V DC operating range of the electronic coil.

TAL contactors are used primarily for controlling three-phase
motors and power circuits. They can also be incorporated into
circuits for isolation, capacitor switching, lighting control,
and other applications that fall within the relevant electrical
utilization categories. The exact application should always be
evaluated against the electrical ratings and installation
requirements.

Model Identification

The complete product ordering code is
1SBL143061R5510, while the corresponding type
reference is TAL9-30-10. The final part of the
ordering code is important because different TAL9-30-10 versions
are available with different DC coil voltage ranges.

For this particular ordering code, the control coil operates over
a 50-90 V DC range. This distinguishes 1SBL143061R5510 from other
visually similar TAL9-30-10 variants. For example, other ordering
codes in the same product family can specify 17-32 V DC,
25-45 V DC, 36-65 V DC, 42-78 V DC, 77-143 V DC, or other coil
ranges. The complete ordering code should therefore be retained
when selecting or replacing the contactor.

Electrical Characteristics

ABB TAL9-30-10 has an AC-1 rated current of 25 A and an AC-3
rated current of 9 A at 415 V. The corresponding AC-3 motor power
rating at 415 V is 4 kW. These ratings describe the contactor’s
suitability for different categories of electrical loads and
should be considered together with the actual motor current,
voltage, starting characteristics, and switching frequency.

The main circuit contains three power poles, allowing the device
to control the three phases of a three-phase load. The auxiliary
circuit provides one normally open contact that can be incorporated
into control logic, status indication, electrical interlocking,
or motor starter holding circuits.

Technical Specifications

DC Coil Operation

One of the defining characteristics of ABB 1SBL143061R5510 is its
50-90 V DC electronic control coil. The wide operating range allows
the contactor to be integrated into DC control systems where the
available control voltage falls within the specified range.

The control terminals must be connected according to the applicable
ABB wiring instructions. Because this is a DC-operated contactor,
coil polarity should be respected. The control circuit should be
checked before energization to confirm that its voltage is suitable
for the 50-90 V DC coil configuration.

Selecting a different TAL9-30-10 coil variant solely because the
mechanical dimensions are similar is not recommended. The coil
voltage is part of the electrical identity of the contactor and
must correspond to the control system.

Main Contact Configuration

The TAL9-30-10 provides three main poles for switching a three-phase
electrical circuit. When the control coil is energized, the main
contacts close and allow current to flow through the controlled
circuit. When the coil is de-energized, the main contacts return
to their normal state.

This configuration is commonly used in motor starter circuits.
Appropriate short-circuit protection, overload protection, and
control equipment should be selected separately according to the
motor and installation requirements. The contactor itself should
not be considered a substitute for the complete motor protection
system.

Auxiliary Contact Function

The built-in normally open auxiliary contact provides a secondary
switching path for control functions. In a conventional motor
starter, it can be used as a holding contact to maintain the
contactor command after a momentary start signal.

In an automated machine, the same auxiliary contact can provide a
feedback signal to a PLC, relay, indicator, or control circuit.
It may also be used for electrical interlocking when several
contactors must operate according to a defined sequence.

Industrial Applications

ABB 1SBL143061R5510 can be applied in industrial control panels,
machine automation systems, motor starters, pump control systems,
ventilation equipment, conveyors, compressors, packaging machinery,
and material-handling equipment.

Its three-pole configuration makes it suitable for three-phase
loads, while the 50-90 V DC electronic coil provides compatibility
with suitable DC control systems. The 9 A AC-3 rating should be
compared with the actual motor operating current rather than
selected only according to motor power.

Other possible applications include switching power circuits,
lighting systems, capacitor-related circuits, and electrical
control assemblies when the relevant utilization category and
electrical characteristics are appropriate.

Installation Considerations

Installation should be performed by qualified electrical personnel
and in accordance with the applicable installation standards.
Before wiring, verify the complete ordering code, main circuit
voltage, load current, control voltage, auxiliary contact
arrangement, and terminal identification.

Particular attention should be given to the 50-90 V DC coil.
Applying a control voltage outside the specified operating range
can result in improper operation or damage to the control circuit.
The polarity of the DC coil terminals should also be observed.

The power circuit should use conductors and protective devices
appropriate for the connected load. Connections should be properly
secured, and the contactor should be installed in an enclosure
with environmental conditions suitable for the equipment.

Replacement and Selection

When ABB 1SBL143061R5510 is used as a replacement for an existing
contactor, the complete ordering code should be compared with the
original device. The TAL9-30-10 family contains multiple coil
configurations, and the coil range is not interchangeable simply
because the contactor has the same type reference.

A replacement should therefore be checked for three main poles,
one normally open auxiliary contact, 9 A AC-3 current rating,
4 kW motor rating at 415 V, and the required 50-90 V DC coil range.
Mechanical dimensions and terminal arrangements should also be
confirmed when the contactor is installed in an existing control
cabinet.

Maintenance

Regular inspection of a contactor installation should include the
main power connections, control terminals, auxiliary circuit,
mechanical movement, and the condition of the surrounding
equipment. Power should be isolated before inspection or
maintenance.

Abnormal noise, excessive heating, inconsistent contact operation,
or unexpected switching behavior can indicate an issue with the
contactor, load, wiring, or control circuit. The DC control voltage
should be checked whenever coil operation appears abnormal.

The condition of the complete motor starter should also be reviewed,
including overload protection and short-circuit protection. Proper
coordination between these components is important for reliable
operation of the overall electrical system.

Conclusion

ABB 1SBL143061R5510 is a TAL9-30-10 three-pole DC-operated
contactor with a 50-90 V DC electronic control coil. It provides
three main power poles, one normally open auxiliary contact, a
25 A AC-1 rating, and a 9 A AC-3 rating at 415 V. The corresponding
AC-3 motor power rating at 415 V is 4 kW.

The complete ordering code is important when identifying this
contactor because the TAL9-30-10 family contains multiple DC coil
voltage configurations. For ABB 1SBL143061R5510, the specified
50-90 V DC coil should be matched with the control system before
installation. With its three-pole switching arrangement and
integrated normally open auxiliary contact, the device is suited
to a wide range of three-phase motor control and industrial
electrical applications.
