ABB SPAU 330 C Overvoltage, Undervoltage and Residual Voltage Relay Supplier and Exporter in India

ABB SPAU 330 C Replacement – REX615 Retrofit

ABB SPAU 330 C is a legacy SPACOM voltage relay. ABB lists the product as not active since 2009, so most current requirements are for replacement of an installed relay, matching spares, plant shutdown requirements or modernisation of older protection panels.

ABB officially includes SPAU 330 C in its SPACOM-to-REX615 Relay Retrofit Program. The ABB retrofit package uses a REX615 relay with a retrofit connector kit and is intended to reduce major rewiring during replacement.

ARP IMPEX handles enquiries for ABB SPAU 330 C replacement relays, legacy SPACOM spares and SPAU 330 C to REX615 retrofit requirements from India.

Description

ARP IMPEX supplies and exports ABB SPAU 330 C voltage relays for existing substations, medium-voltage switchgear, industrial distribution systems and replacement requirements.

SPAU 330 C is an older ABB SPACOM relay used for overvoltage, undervoltage and residual voltage supervision. Its main application is monitoring substation busbar phase-to-phase voltage together with residual voltage in the distribution network.

The relay can also be used where voltage protection or residual voltage supervision is required for:

• Motors
• Transformers
• Generators
• Capacitor banks
• Distribution busbars
• Industrial power systems

ABB also offers the SPAU 330 C with an optional digital disturbance recorder, which makes it different from the simpler SPAU 320 C family. The recorder can be used to review fault events and network operating quantities.

ABB SPAU 330 C Models and Variants

SPAU 330 C is a product family with different module combinations, rather than only one fixed hardware arrangement.

ABB documentation lists the following variants:

ABB SPAU 330 C

The fully equipped SPAU 330 C includes:

• SPCU 1C6 residual overvoltage module

• SPCR 8C27 disturbance recorder

It is used where three-phase voltage supervision and disturbance recording are required without the residual voltage module.

ABB SPAU 330 C5

SPAU 330 C5 includes:

• SPCU 3C14 overvoltage and undervoltage module

This is the simpler three-phase voltage protection version without residual voltage supervision or disturbance recording.

For an exact replacement, always check the C, C1, C2, C3, C4 or C5 designation before ordering.

• Residual overvoltage supervision
• Busbar voltage monitoring
• Earth-fault backup using residual voltage
• Definite-time voltage protection

ABB specifically highlights busbar voltage supervision, general voltage protection, optional disturbance recording, serial communication and continuous self-supervision as key SPAU 330 C functions.

Disturbance Recorder Option

The fully equipped SPAU 330 C and selected variants include the SPCR 8C27 disturbance recorder module.

The recorder can capture analogue and binary information during a fault or abnormal network condition. ABB documentation specifies up to eight analogue and eight binary channels, with recorded events available through the relay communication interface.

For most B2B buyers, the important point is simply whether the existing SPAU 330 C has the disturbance recorder fitted. This should be checked from the relay variant or module arrangement when quoting a replacement.

Applications

ABB SPAU 330 C is commonly found in:

• Substation busbar voltage supervision
• Overvoltage protection
• Undervoltage protection
• Residual overvoltage supervision
• Busbar earth-fault backup
• Medium-voltage switchgear
• Industrial distribution switchgear
• Generator voltage supervision
• Motor voltage protection
• Transformer voltage protection
• Capacitor bank protection

• Fault event recording
• Distribution substations
• Industrial substations
• Existing ABB SPACOM installations
• Legacy protection panels
