ABB SPAA 348 C Replacement and Legacy Spare Availability

Replacement: ABB SPAA 348 C is discontinued. For an existing installation, the exact C/C1–C5 version, complete ABB order code and relay nameplate should be checked before sourcing a matching legacy spare.

Description

ARP IMPEX supplies and exports ABB SPAA 348 C feeder protection relays for replacement, maintenance and existing SPACOM switchgear installations.

SPAA 348 C is an older ABB feeder protection relay used where directional overcurrent, directional short-circuit and directional earth-fault protection is required. It is commonly associated with distribution substations having multiple incoming feeders, parallel feeder arrangements, ring networks and meshed distribution systems. ABB also applied it to radial feeders where some power could feed back from a generator at the consumer end.

ABB supplied the SPAA 348 range in several configurations. Depending on the version, the relay may include directional overcurrent protection, directional earth-fault protection and automatic reclosing.

ABB lists SPAA 348 C as not active since 2007. Most buyers looking for this relay today therefore already have it installed. The requirement is usually for a failed relay replacement, a matching maintenance spare or additional stock before a plant or substation shutdown.

If you are looking for an ABB SPAA 348 C replacement relay, price or legacy spare availability, send us the complete part number and a clear photograph of the existing nameplate. This helps us check the correct version before quotation.

Features

• Directional overcurrent protection
• Directional short-circuit protection
• Sensitive directional earth-fault protection
• Residual overvoltage protection
• Circuit-breaker failure protection
• Automatic reclosing on applicable models
• Suitable for parallel and multiple feeder arrangements
• Circuit-breaker control and signalling

For most replacement enquiries, detailed relay-setting calculations are not needed initially. The part code, model suffix, nameplate, quantity and destination are normally enough to start checking availability.

Applications

SPAA 348 C is commonly found in:

• Medium-voltage feeder protection
• Distribution substations
• Multiple incoming feeder systems
• Parallel feeders between substations
• Ring distribution networks
• Meshed distribution networks
• Busbar protection schemes
• Directional overcurrent protection
• Directional earth-fault protection
• Feeders with generator back-feed
• Industrial distribution systems
• Existing ABB SPACOM panels
• Utility maintenance stock
• Plant and substation shutdown spares

ABB specifically identifies multiple infeeders, parallel feeders, ring and meshed networks, and radial feeders with limited generator back-feed as typical applications.

ABB SPAA 348 C Models

SPAA 348 C is a product family with six main configurations. The exact version is important when sourcing a replacement.

ABB SPAA 348 C

The complete version with directional overcurrent, directional earth-fault and autoreclose functions.

Main order-number group: RS 614 103.

ABB SPAA 348 C1

Version without the automatic reclosing section.

Main order-number group: RS 614 104.

ABB SPAA 348 C2

Version without the directional earth-fault section, while retaining the overcurrent and autoreclose functions.

Main order-number group: RS 614 105.

ABB SPAA 348 C3

Version without directional earth-fault protection and without automatic reclosing.

Main order-number group: RS 614 106.

ABB SPAA 348 C4

Version without the overcurrent protection section.

Main order-number group: RS 614 107.

ABB SPAA 348 C5

Version without the overcurrent section and without automatic reclosing.

Main order-number group: RS 614 108.

ABB also supplied corresponding versions with an RTXP18 test adapter, using the RS 614 303 to RS 614 308 order-number groups.

For an existing installation, SPAA 348 C, C1, C2, C3, C4 and C5 should not automatically be treated as interchangeable.

ABB SPAA 348 C Replacement

Since SPAA 348 C has been discontinued, current enquiries generally come from existing installations.

Typical requirements include:

• Replacement for a failed SPAA 348 C
• SPAA 348 C1–C5 matching spare
• Emergency feeder protection relay replacement
• Utility maintenance stock
• Plant shutdown spare
• Spare for existing SPACOM switchgear

For an exact replacement, please send:

• Complete ABB order code
• Exact model — C, C1, C2, C3, C4 or C5
• Clear nameplate photograph
• Quantity
• Destination country
• Required delivery date

ABB’s current SPACOM-to-REX615 retrofit program does not list SPAA 348 C among its supported models. ABB does list SPAS 348, but SPAS 348 and SPAA 348 C are separate relay types. We therefore would not describe REX615 as an official direct retrofit for SPAA 348 C without specific ABB confirmation.
