Description

REF615E HBFNAEAGAAC1BNA11G: Product Overview
The REF615E HBFNAEAGAAC1BNA11G is a feeder protection relay within ABB’s REF615E series, designed for deployment in medium-voltage (6-36kV) distribution systems to safeguard feeders serving industrial plants, utilities, and renewable energy sites. Its role is to act as a dedicated protection and control unit, positioned between the feeder circuit breaker and the distribution network. In power distribution architectures, it mitigates equipment damage and service interruptions by detecting electrical faults (e.g., short circuits, earth faults, overloads) in real time.
Functionally, the relay processes three-phase current and voltage signals from instrument transformers, applying algorithms for overcurrent (definite/inverse time), differential, earth fault, overvoltage, and undervoltage protection. It executes trip commands to isolate faulty feeder sections via integrated control outputs, while logging fault data (type, timestamp, magnitude) for post-event analysis. As part of the REF615E series, it leverages a platform optimized for distribution protection, offering modular configurability, compliance with IEC 60255/IEC 61850 standards, and integration with substation automation systems. Benefits include reduced outage duration, extended feeder equipment lifespan, and simplified compliance with grid codes.

Core Features & Customer Value​
Comprehensive protection suite: Integrates six core protection functions (overcurrent, differential, earth fault, over/undervoltage) to address common feeder failure modes. For customers, this eliminates the need for multiple standalone relays, reducing panel space, wiring complexity, and maintenance overhead. The differential protection’s high-speed tripping (≤30ms for severe faults) minimizes damage to cables and transformers, critical for utility feeders serving sensitive loads.
Flexible communication and integration: Native support for IEC 61850 and Modbus TCP enables seamless connection to substation SCADA, energy management systems (EMS), and protective relay coordination tools. Engineers can perform remote configuration, firmware updates, and fault analysis without on-site visits, cutting operational costs. For example, in a wind farm, it can coordinate with generator relays to isolate faults in collector feeders.
Robust design for harsh environments: Industrial-grade components and IP51 front-panel rating ensure reliability in substations with dust, humidity, or temperature fluctuations. Wide power supply range (24V DC/110-240V AC) and redundant inputs prevent relay failure due to supply instability. For procurement teams, this extends service life and lowers replacement costs compared to non-industrial alternatives.
Typical Applications​
In a utility substation, the relay protects 33kV distribution feeders supplying residential/commercial areas. Its IEC 61850 interface integrates with the grid operator’s SCADA for real-time load monitoring and fault location, reducing outage restoration time by 30%.
At an industrial plant, it safeguards 11kV feeders powering motor control centers (MCCs) and critical pumps. The earth fault protection detects insulation degradation in long cable runs, preventing nuisance trips while ensuring personnel safety.
In a solar farm, the relay protects 36kV collector feeders connecting photovoltaic arrays to the grid. Its undervoltage protection trips during grid outages to comply with anti-islanding standards, while Modbus TCP logs energy export data for billing.
