ABB SPAS 348 C Replacement – REX615 Retrofit

ABB SPAS 348 C is a legacy feeder protection relay used in older substations and industrial switchgear. Since the model is no longer active, most requirements today are for replacement of an existing relay, maintenance stock, plant shutdown spares or upgrade of an older protection panel.

ABB also supports SPAS 348 through its SPACOM-to-REX615 retrofit program, which makes REX615 an important option when the old relay can no longer be maintained.

For an ABB SPAS 348 C replacement or retrofit quotation, please send:

• Complete ABB order code
• SPAS 348 C, C1, C2 or C3
• Clear nameplate photograph
• Required quantity
• Destination country
• Required delivery schedule

ARP IMPEX supplies and exports ABB SPAS 348 C relays for replacement and maintenance needs and can also assist with REX615 retrofit requirements.

Description

ARP IMPEX is a supplier and exporter of ABB SPAS 348 C feeder protection relays for existing substations, feeder panels, industrial switchgear and plant maintenance.

SPAS 348 C belongs to ABB’s older SPACOM relay range. It was mainly used where directional overcurrent and earth-fault protection were required on feeders.

The relay is commonly found in:

• Incoming feeder panels
• Parallel feeders
• Ring networks
• Distribution substations
• Industrial switchgear
• Networks with power flow in more than one direction

Today, most buyers looking for SPAS 348 C already have the relay installed. They may need an exact spare, a replacement for a failed unit or a modern ABB retrofit.

If you have an existing SPAS 348 C, send us the relay nameplate, and we can check the correct version.

ABB SPAS 348 C Models

SPAS 348 C is available in several versions. The main versions are:

ABB SPAS 348 C

The complete version combines directional overcurrent and directional earth-fault protection.

ABB SPAS 348 C1

This version provides directional overcurrent protection without the separate earth-fault module used in the full version.

ABB SPAS 348 C2

This version combines selected directional overcurrent and earth-fault protection functions.

ABB SPAS 348 C3

This is the simpler version within the family, with fewer protection functions than the fully equipped SPAS 348 C.

Because the C, C1, C2 and C3 versions are not identical, please share the exact model or nameplate when asking for a replacement.
