The ABB PSM0004 2RCA025059A0001 Relion 615 Series Power Supply Module supplies the required operating power to compatible protection and control equipment within an electrical installation. Power supply modules support the operation of electronic protection devices by maintaining the electrical supply needed for measurement processing, protection logic, communication, and status indication.
In a substation or industrial power distribution cabinet, protection relays monitor electrical conditions and respond when configured operating limits are exceeded. Their control electronics require a suitable auxiliary power source to remain operational. A compatible power supply module forms part of this arrangement, supporting the relay’s normal functions and its integration with the wider protection system.
The PSM0004 designation and 2RCA025059A0001 part number provide specific identification for maintenance, spare-parts management, and replacement planning. When selecting a replacement, technicians should verify the installed relay model, auxiliary supply requirements, connection arrangement, and mounting configuration. Compatibility should be established for the complete protection device rather than assumed from the Relion 615 Series name alone.

A power supply module receives electrical energy from its designated input and provides the operating power required by the connected electronic equipment. Its internal circuitry conditions the incoming supply according to the electrical requirements of the supported system.
Within a protection and control installation, the supplied power supports the electronic circuits responsible for processing measurements, executing protection logic, managing communication, and presenting equipment status. These functions depend on the correct auxiliary supply and the integrity of the electrical connections.
For example, a protection relay monitoring a feeder must remain powered to evaluate measured electrical quantities and execute its configured protection functions. If the relay’s operating supply is interrupted or falls outside the permitted range, its availability and associated functions may be affected. The power supply module therefore forms part of the relay’s overall operating arrangement.
When investigating a power-related fault, technicians should distinguish between an input supply problem, a loose or damaged connection, and a failure within the module or host equipment. Verifying the auxiliary supply and checking relevant status indications can help identify the source before a replacement is installed.
Within a compatible Relion 615 Series installation, the PSM0004 Power Supply Module forms part of the electrical arrangement that supports the operation of the protection and control equipment. The wider system combines measurement inputs, protection logic, control interfaces, communication functions, and auxiliary power.

Verify the complete part number, host protection device, auxiliary supply requirements, terminal assignments, and mounting arrangement. The replacement must match the installed hardware configuration and electrical requirements.
Possible symptoms include loss of normal status indications, failure to start, unexpected resets, or unavailable protection and communication functions. These symptoms can also result from an external supply fault or wiring problem, so the input supply should be checked as part of the diagnosis.
Compatibility should not be assumed solely from the product family. The specific relay model, hardware configuration, and power supply arrangement must support the module.
Check the input supply, terminal connections, equipment status indications, and relevant protection-device functions. Confirm that the device starts normally and that any associated alarms or diagnostic indications are resolved before returning the installation to service.
