PRODUCT DESCRIPTION
REF542 PLUS 76A3NDNN36ESU31 Configured feeder protection and control terminal
ABB REF542 PLUS 76A3NDNN36ESU31 is a configured feeder protection and switchbay-control terminal in the REF 542plus family. Its type code selects the basic Ethernet mainboard, a wide-range DC supply and one BIO3 binary I/O board for normal-operation applications.
The documented code positions specify measurement combination 36, comprising three phase CT inputs, three VT inputs, one additional CT input and one additional VT input. The D binary-board option uses an 88–132 V DC input class with a 72 V threshold. Communication option E provides IEC 61850/Modbus TCP through RJ45, and enclosure option S identifies the normal base unit.

SYSTEM INTEGRATION
Integrate REF542 PLUS 76A3NDNN36ESU31 configured feeder protection and control terminal
Map the four current-transformer and four voltage-transformer measurement paths to the configuration selected by analog input code 36. The additional 4–20 mA I/O option is N, so this selection does not include that optional current-loop board.
The first binary I/O slot is D, followed by two empty slots. That BIO3 board provides 14 binary inputs, six power outputs, two signal outputs and one watchdog output. Its voltage class must be matched to the station auxiliary signaling circuits. The E communication option must be engineered with the selected IEC 61850 or Modbus TCP project settings.
The documented code positions specify measurement combination 36, comprising three phase CT inputs, three VT inputs, one additional CT input and one additional VT input. The D binary-board option uses an 88–132 V DC input class with a 72 V threshold. Communication option E provides IEC 61850/Modbus TCP through RJ45, and enclosure option S identifies the normal base unit.
Features:
- Code 36 transformer measurement arrangement
- BIO3 D input class at 88–132 V DC
- IEC 61850/Modbus TCP RJ45 option
The REF542 PLUS 76A3NDNN36ESU31 configured feeder protection and control terminal requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify REF542 PLUS 76A3NDNN36ESU31 configured feeder protection and control terminal
Compare the entire 76A3NDNN36ESU31 type code with the removed terminal. The binary input threshold, transformer input combination and communication medium are critical differences that can be hidden by the common REF542 PLUS family name.
Transfer the controlled protection configuration and compare the installed HMI and cable against the actual unit label and project records. Complete protection injection tests, binary input checks and station-communication verification after replacement; a successful local startup alone does not establish equivalent feeder protection.
S identifies the normal base-unit enclosure, rather than the wide version.
Features:
- Match the complete 15-character type code
- Check CT/VT allocation and input threshold
- Retest binary logic and station reporting
The REF542 PLUS 76A3NDNN36ESU31 configured feeder protection and control terminal requires replacement verification against the complete installed configuration and current manufacturer documentation.

What does analog input code 36 select in 76A3NDNN36ESU31?
It selects three CT plus three VT channels, with one additional CT and one additional VT channel. -
How many BIO3 boards are specified by DNN?
One D-version board is selected in slot 1; the following two N positions leave slots 2 and 3 empty. -
What auxiliary signaling voltage applies to the D binary-input board?
The documented voltage class is 88–132 V DC with a 72 V DC input threshold. -
Does the N analog-I/O option include a 4–20 mA board?
No. N in that code position denotes an empty additional analog-I/O board slot. -
Which network medium is identified by communication option E?
Option E provides IEC 61850/Modbus TCP communication with RJ45 connectors. -
What does enclosure selection S mean for this terminal?
S identifies the normal base-unit enclosure, rather than the wide version. -
What must a purchase order state to retain this REF542 configuration?
Quote the complete REF542 PLUS 76A3NDNN36ESU31 designation and identify the required HMI, license and cable scope. -
