ABB REF615 HCFKAEADABCZDAA11E | Feeder protection and control relay

Description

Product Overview

The ABB REF615 HCFKAEADABCZDAA11E is an advanced feeder protection and control relay belonging to ABB’s Relion® 615 series, designed to safeguard overhead lines, cable feeders, and busbar networks in utility substations and industrial distribution systems. It supports radial, ring, and meshed configurations with or without distributed generation. Its compact, withdrawable design simplifies installation, reduces downtime during maintenance, and enables rapid configuration deployment—ideal for fast-paced operational environments

This intelligent electronic device delivers comprehensive protection—encompassing overcurrent, directional and non-directional earth-fault, thermal, negative-sequence, phase discontinuity, breaker failure, and optional arc flash detection. The relay supports flexible grounding systems, whether isolated, resistance-earthed, compensated, or solidly grounded. Factory-provided standard configurations expedite commissioning; further flexibility is offered through user-programmable logic using PCM600

Integration into modern automation frameworks is seamless. It supports IEC 61850 (Editions 1 & 2), including GOOSE messaging, process bus (IEC 61850-9-2 LE), plus Modbus, DNP3, IEC 60870-5-103, and Profibus via an external converter. High-accuracy time synchronization is achieved through IEEE 1588 v2, while access control is secured by four-level role-based authentication (viewer, operator, engineer, administrator) across front-panel HMI, web HMI, and PCM600 interfaces

Key Features and Benefits

The ABB REF615 HCFKAEADABCZDAA11E consolidates a comprehensive suite of protection features that answer the needs of modern feeder applications. Its multi-stage overcurrent and comprehensive earth-fault protection (including sensitive and intermittent varieties) adapt to a wide range of earthing systems, while thermal, breaker-failure, and phase-discontinuity functions enhance fault discrimination and prevention. Optionally, three-channel arc-fault detection safeguards personnel and equipment in high-risk switchgear environments

Automation is streamlined by robust protocol support. IEC 61850, with GOOSE messaging and process bus capability, reduces wiring overhead while enabling fast inter-device signaling. Time synchronization using IEEE 1588 v2 ensures alignment of fault and event data across systems, bolstering response coordination. Legacy systems are also supported with DNP3, Modbus, and IEC 60870-5-103

User operations are simplified through its intelligent interface offerings. The device has a graphical front-panel display with custom single-line diagram capability, complemented by a web-based HMI for remote monitoring. PCM600 enables flexible configuration, logic programming, and access control administration. A draw-out design supports hot-swap replacements, minimizing downtime and enhancing service continuity

This blend of comprehensive protection, flexible configuration, and user-friendly design positions the ABB REF615 HCFKAEADABCZDAA11E as a competitive solution offering optimized safety, efficiency, and lifecycle value in demanding industrial and utility environments.

Application Scenarios

In conventional utility feeder networks, the ABB REF615 HCFKAEADABCZDAA11E functions as either primary or back-up protection, safeguarding distribution feeders. Its support for auto-reclosing addresses transient faults, maintaining service continuity and reducing manual resets. IEC 61850 integration enhances system-wide coordination, enabling peer-to-peer communication and rapid fault isolation.

Within renewable-heavy microgrid setups, its synchronization and reclosing capabilities enable switching between grid and local generation seamlessly. Real-time measurement and multi-protocol communication also assist in dynamic load management, fostering resilience and scalability.

In industrial sectors like mining, oil & gas, or manufacturing, its rugged protection capabilities and remote interface allow reliable feeder supervision under harsh conditions. Arc protection and web access support safety and remote diagnostics, while PCM600-driven customization supports specific site logic needs.

The relay also excels in meshed or ring network topologies, streamlining feeder protection using GOOSE messaging to eliminate complex cable-based tripping schemes. Across all application scenarios, the ABB REF615 HCFKAEADABCZDAA11E delivers a future-ready balance of protection, automation, and usability—optimizing system safety and performance.

Installation and Maintenance Guidelines

Installation should begin with verifying the suitability of the relay for the feeder’s earthing scheme and the presence of either voltage or current inputs, depending on use-case. Confirm frame compatibility for the draw-out module (177 × 177 × 201 mm) and ensure proper depth for plugin insertion. Plan for Ethernet or serial connectivity and prepare PCM600 for configuration uploads.

During commissioning, insert the relay into its frame, apply power, then access the local or web HMI to verify display, communication, and time synchronization (IEEE 1588). Apply one of the factory-configured setups for immediate service, or use PCM600 to tailor logic and I/O mappings as needed.

For maintenance, always back up configuration and event logs via PCM600 or web HMI before withdrawing the relay. Inspection, firmware validation, and sensor checks (including arc detection) should be completed promptly. Re-insertion should be followed by validation of interface functionality, communication performance, and protection logic—paying special attention to arc detection, reclosing, and time-critical protocols.
