ABB 216VC62a HESG324442R112-F

It is a powerful and widely used intelligent feeder protection relay and an indispensable key device in modern digital power distribution systems.

Detailed Product Description

1. Key Functions & Protection

• Overcurrent Protection: Provides instantaneous, definite time, and inverse time overcurrent protection, which is the core function for handling phase-to-phase short circuits and overloads.

• Earth Fault Protection: Detects and isolates ground faults in the system, including sensitive directional earth fault protection, suitable for different power system grounding methods (e.g., ungrounded, resistance-grounded).

• Auto-reclosing: Automatically recloses the circuit breaker for transient faults (e.g., lightning strikes, wind-blown debris), significantly improving power supply reliability. Typically supports multiple reclosing attempts.

• Measurement & Metering: Real-time measurement of electrical parameters such as current, voltage, power, power factor, frequency, and energy.

• Control Functions: Provides local and remote control capabilities, such as circuit breaker open/close operations.

• Monitoring & Alarming: Monitors circuit breaker status, the relay’s own health, and provides event recording and fault waveform capture for easy fault analysis.

• Communication: Supports multiple industrial standard communication protocols (e.g., IEC 61850, Modbus, DNP3.0), facilitating integration into substation automation systems.

2. Application Areas

This relay is widely used in medium-voltage power distribution systems. Typical application scenarios include:

• In-plant power distribution lines in industrial facilities

• Power supply systems for commercial buildings and data centers

• Distribution networks for municipal utilities and rail transit

• Collector lines in renewable energy power plants (e.g., wind farms, solar parks)

• Feeder lines in utility distribution substations

3. Model Code Breakdown (Inferred)

Although ABB’s complete order number decoding is complex, we can make reasonable inferences based on its naming conventions:

• 216VC62a: This typically refers to a specific hardware version and basic feature set for the REF 615 product line.

• HESG324442R112: This is a more detailed order code that likely defines:

  • Chassis Type (e.g., panel cut-out dimensions)

  • Power Supply Voltage (e.g., 24/48/110/220V DC or 110/230V AC)

  • The number and type of Input/Output contacts (e.g., relay outputs, binary inputs)

  • The type and quantity of Communication interfaces (e.g., Ethernet ports, serial ports)

  • Front plate and Display language options.

• -F: The suffix may indicate specific certifications, special packaging, or regional requirements.

To obtain 100% accurate configuration information, you need to use ABB’s official tools (like CAP – Product Catalog) or contact ABB technical support with the complete order number for a query.
