ABB SPAG 330 C Generator Protection Relay

ABB SPAG 330 C Generator Protection Relay Supplier and Exporter in India

ABB SPAG 330 C Replacement and Legacy Spare Availability

Replacement: ABB SPAG 330 C is discontinued. For an existing installation, the correct replacement should be checked against the complete ABB order code and relay nameplate to match the installed legacy unit.

ARP IMPEX supplies and exports ABB SPAG 330 C generator protection relays for replacement, maintenance and existing generator protection panels.

SPAG 330 C belongs to ABB’s older SPACOM generator protection range. It was mainly used for protecting small and medium-sized generators and their prime movers in land-based power plants as well as marine and offshore installations.

The relay combines several important generator protection functions, including overcurrent, short-circuit, reverse power, overvoltage and earth-fault protection. It is particularly suitable for installations where generator earth-fault protection is required in addition to the basic current and voltage protection functions.

SPAG 330 C is still found in older generator panels where ABB SPACOM protection equipment remains in service. Since the relay is no longer an active ABB product, most requirements today are for replacement of a failed unit, maintenance stock or an additional spare before a plant shutdown.

If you need an ABB SPAG 330 C replacement relay, send the complete order code or a clear photograph of the existing relay nameplate. We can check the correct legacy unit against your required quantity and destination country.

Technical Specifications

• Series: SPACOM / SPAG
• Model: SPAG 330 C
• Product type: Generator protection relay
• Product status: Legacy / discontinued
• Main application: Small and medium generator protection
• Current inputs: 1 A or 5 A
• Voltage input: 100 V or 110 V
• Overcurrent protection: Two-stage
• Short-circuit protection: Available
• Reverse power protection: Available
• Overvoltage protection: Two-stage
• Earth-fault protection: Two-stage neutral/residual current protection
• Communication: SPA serial communication
• Auxiliary supply: 80–265 V AC/DC or 18–80 V DC, depending on version
• Self-supervision: Built-in

For an exact spare, the complete ABB order code and auxiliary supply should be checked from the existing relay rather than assumed from the model number alone.

Features

• Three-phase overcurrent protection
• Short-circuit protection
• Reverse power protection
• Two-stage overvoltage protection
• Two-stage earth-fault protection
• Protection against generator motoring through reverse power supervision
• Local relay status and fault indication
• SPA serial communication
• Connection to higher-level monitoring systems
• Internal hardware and software self-supervision
• Suitable for land-based and marine generator installations

The main difference for many buyers comparing SPAG models is that SPAG 330 C includes earth-fault protection along with reverse power, overcurrent and overvoltage protection.

Applications

SPAG 330 C is commonly used for:

• Small and medium generator protection
• Generator earth-fault protection
• Generator reverse power protection
• Directly connected generators
• Generator protection panels
• Small hydro power plants
• Thermal power stations
• Captive power plants
• Industrial generating stations
• Marine generator systems
• Shipboard power systems
• Offshore installations
• Existing ABB SPACOM panels
• Plant shutdown spare requirements

ABB particularly identifies SPAG 330 C for small and medium generators, including land-based power stations and marine or offshore applications. It is also commonly used for directly connected generators with solidly earthed neutrals.

ABB SPAG 330 C Model

SPAG 330 C is a specific generator protection relay from ABB’s SPACOM range.

The relay contains three main protection sections:

• Overvoltage and reverse power protection
• Three-phase overcurrent protection
• Non-directional earth-fault protection

ABB’s documentation identifies the internal protection modules as:

• SPCP 3C2 – overvoltage and reverse power
• SPCJ 3C3 – three-phase overcurrent
• SPCJ 1C8 – earth-fault protection

These module codes can help when checking an old relay, but for a complete SPAG 330 C replacement, we recommend supplying the full relay order number and nameplate.

ABB SPAG 330 C Replacement

ABB lists SPAG 330 C as not active since 2007. For installations where SPAG 330 C is still operating, buyers may need:

• Replacement for a failed SPAG 330 C
• Matching legacy spare
• Spare for an existing generator panel
• Plant shutdown stock
• Maintenance inventory
• Marine generator spare
• Offshore equipment spare

For an exact replacement, please send:

• Complete ABB order code
• Clear relay nameplate photograph
• Required quantity
• Destination country
• Required delivery schedule

The existing relay should be matched before quotation because input and auxiliary supply arrangements can differ between units.

ABB’s current SPACOM-to-REX615 retrofit program does not list SPAG 330 C among its supported relay models, so we would not describe REX615 as a direct retrofit replacement for this relay.

For an existing panel, the safest starting point is therefore the original SPAG 330 C part number and nameplate.
