ABB SPAA 341 C Feeder Protection Relay

ABB SPAA 341 C Feeder Protection Relay Supplier and Exporter in India

ABB SPAA 341 C Relay Replacement with REX615

Replacement: ABB SPAA 341 C is discontinued and is supported under ABB’s SPACOM-to-REX615 retrofit program. The existing relay version, order code and panel details should be checked before proceeding with the retrofit.

ARP IMPEX supplies and exports ABB SPAA 341 C feeder protection relays for replacement, maintenance spares and existing medium-voltage protection panels.

SPAA 341 C belongs to ABB’s older SPACOM feeder protection range. It was used mainly on radial distribution feeders in isolated-neutral, resistance-earthed and resonant-earthed networks. The relay combines overcurrent, short-circuit, earth-fault and phase discontinuity protection, with autoreclosing available on the appropriate versions.

Unlike simpler feeder relays, SPAA 341 C was supplied in several configurations. Depending on the version, the relay could include conventional overcurrent and earth-fault protection, directional earth-fault protection and an autoreclose module.

This makes the exact model important when replacing an old unit. A buyer asking for only “SPAA 341 C” may have a C1, C2, C3, C4 or C5 configuration installed.

ABB lists SPAA 341 C as not active since 2009. Most current enquiries are therefore for a failed relay, a matching spare for old switchgear, plant shutdown stock or replacement through ABB’s REX615 retrofit program.

If you are looking for ABB SPAA 341 C price, replacement or availability from India, send the complete order number and a clear nameplate photograph so the correct version can be checked before quotation.

Applications

SPAA 341 C was commonly used for:

• Medium-voltage feeder protection
• Radial distribution feeders
• Industrial distribution networks
• Utility substations
• Isolated-neutral networks
• Resistance-earthed networks
• Resonant-earthed networks

ABB SPAA 341 C to REX615 Retrofit

ABB officially lists SPAA 341 C among the SPACOM relay types supported by its SPACOM-to-REX615 Relay Retrofit Program.

ABB’s retrofit solution includes the REX615 relay, retrofit connector kit and documentation. ABB also provides options for configuration and installation support. The program is intended to simplify replacement of supported SPACOM relays and reduce the amount of panel rewiring normally required during a relay upgrade.

A retrofit may be considered when:

• SPAA 341 C has failed
• Legacy spare availability is becoming difficult
• Several SPACOM relays are being replaced
• The existing feeder panel is being upgraded
• Long-term relay support is preferred

Because SPAA 341 C was supplied in several configurations, the exact installed model and panel arrangement should be checked before selecting the retrofit configuration.
