Product Parameters

  • Manufacturer / Brand: ABB
  • Product Family/Series: Relion 615
  • Model: 1MRK002350-AA
  • Type: Feeder Protection and Control Relay (IED)
  • Protection Functions: Includes directional/non-directional phase and ground overcurrent (50/51, 50N/51N, 67, 67N), thermal overload (49), breaker failure (50BF), voltage protection (27/59), and automatic reclosing (79).
  • Control & Monitoring: Circuit breaker control, extensive metering (current, voltage, power, energy, frequency), event logging, and disturbance recorder (oscillography).
  • Inputs/Outputs: Binary inputs for status signals, relay (binary) outputs for tripping/alarming, and analog inputs for current/voltage measurement via standard instrument transformers.
  • Communications: Multiple protocol support typically including IEC 61850 (client/server and GOOSE), Modbus RTU/TCP, and IEC 60870-5-103/104 for seamless integration into substation automation systems.
  • Power Supply: Available in common DC/AC voltage ranges (e.g., 24-48V DC, 110-240V DC/AC).
  • Standards: Compliant with relevant IEC and IEEE standards for protection relays.

Advantages and Features

  • Integrated Multifunction Design: Replaces multiple discrete relays and meters, reducing panel space, wiring complexity, and overall system cost.
  • IEC 61850 Ready: Native support for the IEC 61850 standard enables advanced substation communication, interoperability, and fast peer-to-peer messaging via GOOSE for interlocking and protection schemes.
  • Advanced Diagnostics: Built-in disturbance recorder and detailed event log with time-stamping provide powerful tools for post-fault analysis and system troubleshooting.
  • User-Friendly Configuration: Utilizes ABB’s PCM600 or similar engineering tool for intuitive setting management, logic configuration, and documentation.
  • High Reliability: Built with industrial-grade components and designed for continuous, reliable operation in demanding electrical environments.

Application Cases in Application Fields

  • Manufacturing Plant Power Distribution: In a factory’s main medium-voltage (MV) switchgear, the protects incoming feeders and large motor circuits. It provides selective overcurrent protection, ensuring a fault on one feeder does not trip the main incoming breaker, minimizing production downtime.
  • Renewable Energy Substation: At a solar or wind farm collector substation, the relay protects the feeder connecting the power transformer to the grid. It uses directional overcurrent elements to correctly identify faults on the protected line versus those back-fed from the generation source.
  • Infrastructure & Utilities: In a water treatment facility’s electrical network, the device manages the protection of critical pump motors, offering thermal overload protection to prevent motor damage from prolonged overcurrent conditions and enabling automatic restart sequences.

Comparisons with Competing Products

  • Vs. Electromechanical Relays: The ABB 1MRK002350-AA offers vastly superior functionality, precision, programmability, and diagnostic capabilities. It eliminates the need for calibration and provides communication features that traditional relays lack.
  • Vs. Basic Digital Relays: While simpler digital relays may offer core protection, the 1MRK002350-AA, as part of the Relion 615 series, typically provides a richer set of standard functions, better communication protocol support (especially IEC 61850), and more advanced tools within its engineering software suite.
  • Vs. PLC-based Protection: A PLC with protection modules can perform some protection logic, but it is not certified or typically as optimized for high-speed, failsafe protection tasks as a dedicated IED like the , which is designed and tested for this sole purpose.

Selection Suggestions and Precautions

  1. Confirm Functional Scope: Verify that the specific protection and control functions (e.g., directional protection, autorecloser) included in the configuration match your application’s single-line diagram and protection philosophy.
  2. Check Communication Protocol Requirements: Ensure the relay’s communication option (e.g., IEC 61850, Modbus TCP) is compatible with your substation’s SCADA, gateway, or engineering tool. The ABB 1MRK002350-AA often offers flexibility here.
  3. Verify CT/VT Requirements: Match the relay’s nominal current and voltage input ratings (e.g., 1A/5A, 110V/120V) to the secondary ratings of your instrument transformers (CTs and VTs).
  4. Plan for Engineering Tools: Account for the need for ABB’s configuration software (PCM600) and possibly specific device description files (DDs or ICDs) for integration.
  5. Consider Cybersecurity: For networked devices, implement appropriate cybersecurity measures as per IEC 62351, including firewall rules, VLAN segmentation, and disabling unused services on the .
  6. Source from Authorized Suppliers: Purchase from authorized ABB channels to ensure you receive genuine hardware with the correct firmware and access to technical support. You can explore this product further here: ABB 1MRK002350-AA.
