ABB SPAA 345 C Replacement and Legacy Spare Availability

Replacement: ABB SPAA 345 C is discontinued. For an existing installation, the exact model, ABB order code and relay nameplate should be checked before sourcing a matching legacy spare.

Description

ARP IMPEX supplies and exports ABB SPAA 345 C feeder protection relays for replacement, maintenance and existing SPACOM switchgear installations.

SPAA 345 C is an older ABB feeder protection relay used in medium-voltage distribution systems. It covers feeder overcurrent, short-circuit and earth-fault protection. Depending on the version, the relay can also provide directional earth-fault protection, transient earth-fault detection and automatic reclosing.

ABB supplied SPAA 345 C in several versions, including SPAA 345 C, C1, C2, C3, C4 and C5. The protection functions are not the same across all versions, so the exact model should be checked before selecting a replacement.

ABB lists SPAA 345 C as a discontinued product. Most requirements today come from plants, utilities and maintenance companies that already have the relay installed and need a failed unit replaced, an additional shutdown spare or another matching relay for an older panel.

If you are looking for an ABB SPAA 345 C replacement relay, SPAA 345 C price or legacy spare availability, send us the complete ABB part number and a clear photograph of the existing relay nameplate. ARP IMPEX can check the requirement against the required quantity and destination country.

Features

• Feeder overcurrent protection
• Short-circuit protection
• Earth-fault protection
• Directional earth-fault protection on applicable versions
• Transient earth-fault detection
• Intermittent earth-fault detection
• Phase discontinuity supervision
• Circuit-breaker failure protection
• Automatic reclosing on selected versions
• Local fault indication
• SPA serial communication
• Internal relay supervision

The main reason to identify the exact SPAA 345 C version is that not every model includes the same protection and autoreclose functions.

Applications

SPAA 345 C is commonly found in:

• Medium-voltage distribution feeders
• Radial feeder protection panels
• Distribution substations
• Industrial switchgear
• Utility distribution systems
• Isolated-neutral networks
• Resonant-earthed networks
• Partially earthed networks
• Cable feeder protection
• Earth-fault protection schemes
• Existing ABB SPACOM panels
• Plant shutdown and maintenance spares

The relay is still found in older substations and industrial plants where the original ABB SPACOM protection system remains in service.

ABB SPAA 345 C Models

SPAA 345 C is a product family with several versions.

SPAA 345 C

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

SPAA 345 C1

Version without the autoreclose section.

SPAA 345 C2

Version without the transient/directional earth-fault section but with autoreclose.

SPAA 345 C3

A simpler version without the transient/directional earth-fault and autoreclose sections.

SPAA 345 C4

Version mainly covering transient/directional earth-fault protection together with autoreclose functions.

SPAA 345 C5

A more limited version mainly intended for transient/directional earth-fault protection.
For an existing installation, SPAA 345 C, C1, C2, C3, C4 and C5 should not automatically be treated as interchangeable.

ABB SPAA 345 C Replacement

SPAA 345 C is no longer an active ABB product, but many units are still installed in older switchgear.

Current enquiries are usually for:

• Failed SPAA 345 C replacement
• SPAA 345 C1 to C5 legacy spare
• Plant shutdown stock
• Emergency feeder relay replacement
• Spare for existing switchgear
• Maintenance inventory
• Older SPACOM panel support

For an exact replacement, please send:

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

ABB does not currently list SPAA 345 C under its published SPACOM-to-REX615 retrofit program, so we do not describe REX615 as a direct replacement for this relay.

For an existing panel, checking the original relay first is the safest way to avoid supplying the wrong version.
