The ABB REF615E-D 2RCA023019A0004C, also cataloged as the REF615 Feeder Protection and Control Relay, processes feeder current signals and executes configured protection and control functions within the REF615 platform.

Model and Ordering Code

The supplied identification includes REF615E-D, REF615, and ordering code 2RCA023019A0004C. The additional code HBFCACABNCA1BNN1XD is retained as supplied; its individual characters are not decoded because no verified coding matrix was provided.

Hardware Specifications

Protection Relay Electrical Interface

The REF615E-D accepts current measurement inputs identified as I and Io, with the supplied configuration specifying 1/5 A rated current values. The auxiliary supply range covers both AC and DC sources as specified above.

The relay is configured for feeder protection and control functions. Actual protection elements, binary I/O assignments, communication interfaces, and application configuration depend on the specific REF615 variant and engineering settings.

ABB Protection and Control Characteristics

REF615 is part of ABB's Relion protection and control product family. The relay processes measured electrical quantities and applies configured protection logic to feeder circuits.

The supplied unit is identified with 50/60 Hz operation and less than 10 W power consumption. The auxiliary supply accepts 48-250 VDC or 100-240 VAC. Protection settings must correspond to the installed current transformer ratios and the configured application.

Installation and Wiring

Panel installation

• Confirm the mounting cutout and mechanical dimensions against the applicable REF615 installation documentation.
• Install the relay with adequate clearance for terminal access and cable routing.
• Verify that the relay identification matches the intended protection application before energization.

Auxiliary power

• Confirm the available supply is within 48-250 VDC or 100-240 VAC.
• Observe the correct polarity when using a DC auxiliary supply.
• Protect the auxiliary circuit according to the switchgear and protection-panel design.
• Do not apply AC and DC auxiliary supplies simultaneously unless explicitly permitted by the applicable documentation.

Current transformer circuits

• Verify CT secondary ratings against the configured 1/5 A current inputs.
• Confirm I and Io wiring before commissioning.
• CT secondary circuits must be handled according to the applicable protection-panel safety procedure.
• Do not open an energized CT secondary circuit.

Grounding and signal routing

• Connect protective grounding according to the panel grounding design.
• Route CT and communication wiring separately from high-current switching conductors where practical.
• Use the specified shield termination method for any shielded communication or signal cable.
• Check terminal tightness and conductor identification before energizing the relay.

Frequently Asked Questions

• What is the auxiliary supply range of REF615E-D?

  The supplied identification specifies 48-250 VDC or 100-240 VAC for the auxiliary supply. The actual panel supply must remain within the applicable operating limits.

• What are the rated current inputs?

  The supplied data identifies both I and Io inputs as 1/5 A. CT secondary selection and relay settings must correspond to the installed protection circuit.

• What is the rated operating frequency?

  The specified rated frequency is 50/60 Hz. The configured relay application must match the frequency of the monitored electrical system.

• What is the relay power consumption?

  The supplied product identification states power consumption of less than 10 W. Actual panel power calculations should use the applicable technical documentation.

• Can the relay be installed with an energized CT circuit?

  CT circuits should not be opened while energized. Follow the switchgear protection procedure and isolate or short the CT circuit as required before wiring work.

• Does REF615E-D support both AC and DC auxiliary power?

  Yes. The supplied identification specifies 48-250 VDC and 100-240 VAC auxiliary supply ranges. The selected source must be wired according to the relay terminal configuration.

• What should be checked before replacing the relay?

  Verify the REF615E-D model, 2RCA023019A0004C ordering code, CT ratings, auxiliary supply, wiring, and protection configuration before replacement.

• Does the supplied data define the communication protocol?

  No specific communication protocol is stated in the supplied data. Communication interfaces and protocol support should therefore be verified from the exact REF615 variant documentation.
