ABB SPAG 332 C Generator Protection Relay

ABB SPAG 332 C Generator Protection Relay Supplier and Exporter in India

ABB SPAG 332 C Relay Replacement and Legacy Spare Availability

Replacement: ABB SPAG 332 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 332 C generator protection relays for replacement, maintenance and existing generator protection panels.

SPAG 332 C belongs to ABB’s older SPACOM generator protection range. It was mainly used for small and medium-sized generators and their prime movers in hydro power plants, thermal power stations and other generating plants. The relay was also approved for marine and offshore installations.

SPAG 332 C combines overcurrent, short-circuit, reverse power, overvoltage and directional earth-fault protection in one relay. ABB also identifies it as a suitable choice for installations where several directly connected generators operate in parallel on the same busbar.

Since the model is no longer active, most buyers looking for SPAG 332 C today already have the relay installed. The need is generally for replacement of a failed relay, maintenance stock, a shutdown spare or another matching unit for an existing generator panel.

If you need an ABB SPAG 332 C replacement relay, send us the complete ABB order number or a clear photograph of the existing relay nameplate. We can check the correct legacy version against your quantity and destination country.

For an exact replacement, the complete ABB order code should be checked because the frequency and auxiliary supply arrangement can differ between versions.

Features

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

For replacement enquiries, detailed protection calculations are normally not required at the first stage. The part number and existing relay nameplate are more useful for checking the correct unit.

Applications

SPAG 332 C is commonly used for:

• Small generator protection
• Medium-sized generator protection
• Parallel generator protection
• Generators operating on a common busbar
• Generator reverse power protection
• Generator earth-fault protection
• Small hydro power plants
• Thermal power stations
• Captive power plants
• Industrial generating stations
• Generator protection panels
• Marine generator systems
• Offshore installations
• Existing ABB SPACOM panels
• Plant shutdown spare requirements

ABB particularly identifies SPAG 332 C for small and medium generators and for installations with several directly connected generators operating in parallel on the same busbar.

ABB SPAG 332 Models

The SPAG 332 range was supplied in two main versions:

ABB SPAG 332 B

SPAG 332 B is the version without serial communication capability.

ABB SPAG 332 C

SPAG 332 C includes a serial communication interface for connection to higher-level monitoring and control systems through ABB’s SPA communication system.

The protection functions are closely related, but the communication arrangement is different. For an existing installation, SPAG 332 B and SPAG 332 C should therefore not automatically be treated as interchangeable.

ABB SPAG 332 C Replacement

ABB lists SPAG 332 C as not active since 2007. For generators where this relay remains in service, the requirement may be:

• Replacement for a failed SPAG 332 C
• Matching legacy spare
• Spare for an existing generator panel
• Plant shutdown stock
• Maintenance inventory
• Marine generator spare
• Offshore installation spare

For an exact replacement, please send:

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

ABB’s current SPACOM retrofit program lists selected legacy relay models but does not currently list SPAG 332 C among the supported types.

For this reason, we do not describe another ABB relay as a direct retrofit replacement for SPAG 332 C. The original part code and nameplate should be checked first when the requirement is for an existing panel.
