ABB’s product information specifically identifies the 3BSE003387R1 as a power supply unit with AC 115 V input and DC 24 V, 10 A output. ABB also lists the 10 A spare fuse reference and identifies SA161M as the coated marine-classified version.
Product Introduction
The ABB 3BSE003387R1 is a dedicated power supply unit used in ABB Advant Master and related legacy control-system installations. Its primary function is straightforward: convert the available 115 VAC supply into 24 VDC power for electronic control equipment and associated system loads. With a 10 A output rating, it serves as a cabinet-level power source rather than a PLC CPU, I/O module, or communication interface.
The ABB 3BSE003387R1 is particularly relevant when maintaining older ABB DCS installations where the original power architecture must remain intact. The exact part number matters because the SA-series contains several different power-supply variants, including SA162, SA167, SA168, SA171, and SA172.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
Power-supply failures in legacy DCS cabinets are often misdiagnosed as controller or I/O failures. A marginal 24 VDC supply can cause multiple modules to reset, communication faults to appear intermittently, or field signals to become unstable. Before replacing a controller, the output voltage and loaded behavior should be checked.
Typical Applications
1. ABB Advant Master control cabinets
The provides the 24 VDC supply required by compatible control-system equipment.
2. Legacy DCS maintenance
It is useful as a direct maintenance spare where an existing cabinet was designed around the ABB SA-series power architecture.
3. Industrial control power distribution
The 24 VDC output can supply compatible electronic control loads within the unit’s 10 A rating.
4. Power-system refurbishment
During cabinet refurbishment, the can be retained where the original 115 VAC input and 24 VDC distribution arrangement remain part of the system design.
Technical Pitfalls
Verify the input voltage before replacement.
The is specifically identified by ABB as an AC 115 V / DC 24 V, 10 A power supply. Do not substitute another SA-series unit simply because its physical dimensions appear similar.
Check the complete DC load.
The 10 A rating is the supply capacity; the actual cabinet load, startup current, downstream distribution, and ambient conditions still need to be evaluated.
Inspect the 24 VDC distribution circuit.
If the repeatedly trips or its output collapses under load, check downstream wiring, terminal blocks, fuses, and connected modules before assuming the power supply itself is defective.
Do not confuse with SA161M.
ABB identifies SA161M 3BSE016211R1 as the coated marine-classified version. The two should not be treated as interchangeable without checking the environmental and certification requirements of the installation.
Check the fuse specification.
ABB lists a 10 A / 5672827-10 spare fuse for the . Using an incorrectly rated protective device can alter the intended protection of the power supply and downstream circuitry.
Do not confuse it with newer ABB power supplies.
The belongs to a legacy Advant Master architecture. Modern ABB control-system power modules are not automatically suitable substitutes even when they provide 24 VDC.
Watch for age-related degradation.
In long-service DCS cabinets, electrolytic capacitors, terminal connections, cooling paths, and insulation can degrade with time. An intermittent low-voltage condition can be more difficult to diagnose than a complete power-supply failure.

Procurement Note
For an ABB 3BSE003387R1 replacement, verify the 115 VAC input, 24 VDC output, 10 A rating, complete part number, fuse arrangement, and installed Advant Master cabinet configuration.
For used industrial automation inventory, inspect the input/output terminals, fuse holder, enclosure, PCB condition, signs of heat exposure, and output-voltage stability. A meaningful test should include both no-load and controlled-load checks; a supply that produces 24 VDC unloaded can still fail when the cabinet reaches normal operating current.
