Product Overview

ABB 1SBL143061R5810 corresponds to the TAL9-30-10 contactor with a
42-78 V DC control coil. The TAL9 range is intended for three-phase
circuit switching and motor control. The 30-10 designation identifies
the three-main-pole configuration together with one normally open
auxiliary contact.

The contactor is rated at 9 A for AC-3 utilization at 415 V and has
a motor power rating of 4 kW at 415 V. Its AC-1 general-purpose
current rating is 25 A. These ratings make the TAL9-30-10 suitable
for compact motor starters, control panels, machinery, pumps, fans,
compressors, conveyors, and other industrial loads where a
three-pole contactor is required.

Model Identification

The complete ordering code is 1SBL143061R5810.
The corresponding ABB type designation is
TAL9-30-10. The ordering-code structure belongs
to ABB’s TAL contactor family, where the coil voltage is represented
by the code section before the final auxiliary-contact designation.

For this specific product, the R5810 ordering code identifies a
42-78 V DC electronic coil configuration. This voltage range is
important when matching the contactor to a PLC output, control
transformer arrangement, DC control circuit, or other command
source. The control voltage should always be checked against the
actual control circuit before installation.

Main Electrical Characteristics

The ABB TAL9-30-10 provides three main contacts for switching a
three-phase load. Its AC-3 rated operational current is 9 A at
common supply voltages including 380/400 V and 415 V. At 415 V,
the associated AC-3 motor power rating is 4 kW. The contactor also
has an AC-1 general-purpose rating of 25 A.

The auxiliary contact arrangement is one normally open contact.
This auxiliary circuit can be used for electrical interlocking,
contactor status feedback, holding circuits, PLC input signals,
control logic, or indication. The auxiliary contact is electrically
separated from the main power path and provides an additional
control function within the starter or automation circuit.

Technical Specifications

Three-Pole Switching Function

The three main poles of the TAL9-30-10 allow simultaneous switching
of the three phases of a three-phase motor or other compatible
electrical load. When the control coil is energized within its
specified DC operating range, the main contacts change state and
connect the controlled circuit. When the coil is de-energized, the
contactor returns to its normal position.

This operating principle allows the contactor to be integrated into
conventional motor starter circuits and automated control systems.
A PLC, relay output, push-button station, or other control device
can provide the command signal, provided that the control circuit
is compatible with the 42-78 V DC coil requirements.

Auxiliary Contact Function

The built-in normally open auxiliary contact provides an additional
signal path for control and monitoring. In a conventional motor
starter, it can be used as a holding contact so that the contactor
remains energized after a momentary start command. In automated
equipment, the same contact can provide an electrical status signal
to a PLC or relay logic circuit.

The auxiliary contact can also participate in interlocking
arrangements where several contactors must operate according to a
defined sequence. Correct contact numbering and circuit design
should be verified from the applicable ABB documentation before
wiring.

Industrial Applications

ABB 1SBL143061R5810 can be used in industrial motor control panels
and machine automation systems where a compact three-pole contactor
with a DC control circuit is required. Typical applications include
pumps, ventilation equipment, conveyors, compressors, machine
tools, material handling systems, packaging equipment, and general
motor starter assemblies.

The 9 A AC-3 rating and 4 kW motor rating at 415 V make this
contactor particularly applicable to smaller three-phase motors.
Application selection should consider the motor nameplate current,
supply voltage, utilization category, starting conditions,
switching frequency, ambient temperature, and the complete
protection arrangement.

Installation Considerations

Installation should be carried out by qualified personnel using a
control circuit and power circuit designed for the applicable
electrical ratings. Before energizing the device, verify the
ordering code, coil voltage, main circuit voltage, load current,
auxiliary contact requirements, and conductor connections.

The 42-78 V DC coil specification is especially important. A
control source outside the permitted operating range should not
be connected to the coil. Incorrect control voltage can prevent
reliable operation or cause damage to the control circuit.

Power conductors should be selected according to the installation
standard and the actual load. Terminal connections should be
tightened according to the applicable ABB installation instructions.
Adequate spacing, enclosure conditions, temperature, and ventilation
should also be considered when the contactor is installed in a
control cabinet.

Selection and Replacement

When replacing an existing TAL9 contactor, the complete ordering
code should be compared rather than selecting a device only by
appearance or nominal current. The 1SBL143061R5810 designation
identifies a specific TAL9-30-10 configuration with a 42-78 V DC
coil and one normally open auxiliary contact.

A replacement contactor should therefore be checked for the same
number of main poles, auxiliary contact arrangement, coil operating
range, AC-3 current rating, motor power rating, mounting
requirements, and terminal arrangement. Other TAL9 variants may
have different coil ranges or auxiliary contact configurations even
though their mechanical appearance is similar.

Maintenance

Periodic inspection should focus on the condition of the main
terminals, control connections, contact surfaces, mechanical
movement, and surrounding installation. The contactor should be
isolated from the power source before inspection or maintenance.

If abnormal heating, contact wear, mechanical noise, inconsistent
operation, or control-circuit problems are observed, the complete
application should be checked. Particular attention should be paid
to the DC control voltage and the load current because unsuitable
operating conditions can affect contactor performance and service
life.

Conclusion

ABB 1SBL143061R5810 is the TAL9-30-10 three-pole DC-operated
contactor configured with a 42-78 V DC electronic coil. It provides
a 9 A AC-3 rating and a 4 kW motor rating at 415 V, together with
one normally open auxiliary contact. These characteristics make it
suitable for three-phase motor switching and industrial control
applications where a DC-operated contactor is required.

For system integration or replacement work, the complete ordering
code should be used to confirm the exact configuration. Particular
attention should be given to the 42-78 V DC control range, three
main poles, one normally open auxiliary contact, and the applicable
AC-3 load rating.
