Product Introduction
When a synchronizing relay fails or a spare is needed for planned maintenance, generator paralleling and busbar tie operations may lose automatic voltage, frequency, and phase-angle supervision. The ABB SYN5201A-Z V217, order code 3BHB006714R0217, is a single-channel SYNCHROTACT 5 synchronizing relay used for generator, feeder, and busbar paralleling in power plants, substations, and industrial cogeneration systems.
It measures voltage difference, frequency difference, and phase angle between two sources, calculates the breaker lead angle, and issues a closing command when synchronizing conditions are met. This version is an earlier SYN5201A-Z variant; newer versions such as V277 may offer updated firmware or expanded parameter-set capacity, so replacement should be verified against the existing device and application.

Key Selling Points & Differentiators
- Exact V217 replacement: Supplied as SYN5201A-Z V217, 3BHB006714R0217, for like-for-like replacement.
- Single-channel synchronizer: Suitable for one paralleling point with 7 selectable parameter sets.
- SYNCHROTACT 5 reliability: SIL2-rated design for generator and busbar synchronizing applications.
- Flexible integration: Supports Modbus, Profibus, and optional IEC 61850 depending on configuration.
- Factory-sealed supply: Shipped with ESD-safe handling and visual QA before dispatch.
- Not recommended for dual-channel redundancy requirements where SYN5202A-Z or SYN5302 is specified, or for applications requiring the latest V277 firmware/features without engineering review.
Quality Transparency SOP
- Visual inspection: Check front panel, display, keypad, connectors, and mounting hardware.
- ESD-safe handling: Packed in anti-static protection to prevent damage to internal electronics.
- Connector verification: Inspect voltage inputs, digital I/O terminals, communication ports, and power terminals.
- Nameplate cross-check: Confirm SYN5201A-Z V217 and 3BHB006714R0217 before shipment.
- Functional validation: When compatible test equipment is available, verify voltage/frequency measurement, synchronizing supervision, output relay operation, and communication link. Full validation depends on the host breaker, PT/CT scheme, and paralleling logic.
Technical Risk Avoidance
❗ Confirm the version. V217 is an earlier SYN5201A-Z version; V277 and other revisions may differ in firmware or parameter-set capacity.
❗ Do not substitute channel count blindly. SYN5201A-Z is single-channel; SYN5202A-Z is dual-channel; SYN5302 is a four-channel redundant system.
❗ Verify synchronizing parameters. Voltage difference, frequency difference, phase angle, and lead-angle settings must match the existing breaker and generator characteristics.
❗ Check communication options. Modbus, Profibus, and IEC 61850 availability depends on the installed option; confirm before integration.
❗ Follow protection and LOTO procedures. Synchronizing relay replacement should be performed by qualified protection and control engineers during a planned outage.
Buyer’s FAQ
Is this an original ABB part?
Yes. The listing is for ABB SYN5201A-Z V217, order code 3BHB006714R0217, as a new original/new surplus, factory-sealed unit.
What does SYN5201A-Z do?
It is a single-channel automatic synchronizing relay that monitors voltage, frequency, and phase angle, then issues a breaker closing command when synchronizing conditions are met.
Can V217 replace V277 or other SYN5201 versions?
Not automatically. V217 and V277 may differ in firmware, parameter sets, or features. Replacement should be confirmed against the existing nameplate and application.
What condition is the unit?
New Original (New Surplus) / Factory Sealed, unless otherwise stated in the product listing. Photos and batch details can be confirmed before dispatch.
Do you offer a warranty?
Yes. A standard warranty applies from receipt. Exact terms depend on stock batch and installation conditions. Installation and testing should be performed by qualified protection engineers.
