ABB SYN 5100A-Z V0221 3BHB006717R0221 Synchrocheck Device

Description

Technical Specifications

Specifications above follow ABB’s SYNCHROTACT 5 ordering information. Confirm the complete nameplate and applicable manual before installation.

Product Overview

The ABB SYN 5100A-Z V0221, part number 3BHB006717R0221, belongs to the SYNCHROTACT 5 family of synchronization equipment. Its role is to monitor whether electrical conditions are suitable for closing a circuit breaker during manual or controlled paralleling operations. Typical applications include generator-to-busbar connections, power-line paralleling, and other installations where two AC sources must be checked before connection.

The distinction between a synchrocheck device and an automatic synchronizer is important. The SYN 5100 checks synchronization conditions; it does not perform the automatic voltage and frequency matching provided by applicable SYN 5200-series devices. In a typical installation, it monitors electrical measurements and permits or blocks breaker closing according to configured limits and the connected control circuit. Correct operation depends on the measurement wiring, configured parameters, breaker logic, and the wider protection scheme.

The 0221 ordering code indicates the communication, frequency, and parameter-set options described in ABB’s SYNCHROTACT 5 documentation: no communication option, 50/60 Hz nominal frequency, and one parameter set. The exact auxiliary supply and electrical connections should still be confirmed against the unit’s nameplate and the relevant manual.

For maintenance and procurement teams, the 3BHB006717R0221 identifier is essential when sourcing a replacement. A similar-looking SYNCHROTACT device may have a different function, supply requirement, or configuration. Before ordering, compare the complete part number, option code, mounting arrangement, and existing system drawings. For commissioning, verify the measurement circuits and breaker-close interlocks before returning the device to service.

Major Features and Advantages

1. Synchronization-condition monitoring

The SYN 5100A-Z V0221 is designed to monitor synchronization conditions before a paralleling operation. This helps ensure that breaker closing is governed by configured electrical criteria rather than operator judgment alone.

2. Synchrocheck for manual or automatic control schemes

ABB describes the SYN 5100 as a synchrocheck device. It can be used as a monitoring element in a manual synchronization scheme or in conjunction with other equipment that performs automatic synchronization. The SYN 5100 itself does not provide automatic synchronization.

3. Paralleling of electrical lines

The SYN 5100 family supports paralleling checks for two lines. Whether the device is suitable for a particular generator, busbar, or line connection depends on the voltage measurement arrangement, frequency, configuration, and approved application design.

4. Defined frequency and parameter configuration

The 0221 option code corresponds to 50/60 Hz operation and one parameter set in ABB’s published ordering scheme. This provides a clear basis for checking the device against the intended electrical system. The configured thresholds and commissioning values must be verified independently.

5. Compact installation format

ABB’s documentation identifies DIN-rail mounting for the SYN 5100 family. Confirm the exact mounting arrangement and required clearance against the installed unit and cabinet design before planning a replacement.

6. Integration into a wider protection scheme

A synchrocheck device is one part of the breaker-closing circuit. Its effectiveness depends on suitable voltage transformers, correct phase connections, properly designed interlocks, and functional breaker controls. It does not replace generator protection, circuit-breaker protection, or site electrical safety procedures.

Typical Applications

• Generator-to-busbar connection: Checks synchronization conditions before a generator breaker closes.
• Power-station switchgear: Supports controlled paralleling operations within an approved electrical design.
• Substation line paralleling: Monitors conditions before connecting two AC lines.
• Manual synchronization systems: Provides synchrocheck supervision alongside operator-controlled synchronization.
• Automatic synchronization systems: Serves as a separate monitoring element when paired with a compatible automatic synchronizer.
• Legacy equipment maintenance: Replaces an existing SYNCHROTACT 5 synchrocheck device after exact configuration verification.

The correct application depends on the electrical single-line diagram, measurement transformers, breaker logic, and synchronization settings. The SYN 5100 should not be substituted for an automatic synchronizer where automatic adjustment of generator voltage or frequency is required.

Installation and Maintenance

Before installing the ABB SYN 5100A-Z V0221, confirm the full part number and review the approved wiring diagrams for the application. Synchronization monitoring is part of the circuit-breaker closing logic, so an incorrect replacement or configuration can create serious electrical risks.

1. Verify identification: Check the nameplate, part number, ordering code, and revision against the approved bill of materials.
2. Confirm the supply: Verify the auxiliary AC or DC supply against the exact device specification.
3. Inspect measurement circuits: Check voltage transformer ratios, phase sequence, polarity, grounding, and terminal wiring.
4. Review settings: Record the existing synchronization thresholds and parameter configuration before making changes.
5. Check interlocks: Verify the breaker-close circuit, position feedback, and required blocking logic.
6. Perform functional testing: Follow the approved commissioning procedure to test valid and invalid synchronization conditions.
7. Document the result: Record the installed part number, settings, inspection results, and commissioning checks.

Do not bypass synchrocheck interlocks to force breaker closing. Testing and commissioning must follow site electrical-safety rules and the applicable ABB operating instructions.

Product Assurance

When sourcing the 3BHB006717R0221, request a clear nameplate photograph and confirmation of the complete model and 0221 option code. For used or refurbished units, ask what functional tests have been completed and whether records are available. A visual inspection or power-on check alone does not verify the accuracy of synchronization monitoring or the behavior of the output contacts.

Before accepting a replacement, confirm its auxiliary supply, nominal frequency, parameter configuration, mounting arrangement, and wiring compatibility. If a supplier proposes a SYN 5200-series device as an alternative, review the application carefully because automatic synchronization functions and hardware configuration differ from the SYN 5100.

Procurement recommendation: Treat the ABB SYN 5100A-Z V0221 3BHB006717R0221 as a synchrocheck monitoring device. Verify the ordering code and application wiring before purchase, and complete the required functional tests before returning the equipment to service.
