ABB SPAJ 140 C Overcurrent and Earth-Fault Relay

ABB SPAJ 140 C Overcurrent and Earth-Fault Relay Supplier and Exporter in India

ARP IMPEX supplies and exports ABB SPAJ 140 C combined overcurrent and earth-fault relays for existing switchgear, substations, industrial plants and replacement requirements.

SPAJ 140 C is an older ABB SPACOM protection relay widely used for overcurrent, short-circuit and earth-fault protection of radial feeders. It combines phase overcurrent and earth-fault protection in one unit and is commonly found in older medium-voltage switchgear and industrial distribution panels.

ABB SPAJ 140 C is now a legacy product, and ABB lists it as not active since 2016. Most enquiries today are therefore for an existing relay replacement, matching spare or upgrade to a newer ABB protection relay.

If you have an installed SPAJ 140 C and need the same relay, send us the complete order code and a clear photograph of the nameplate. We can check the requirement based on the available details.

ARP IMPEX handles enquiries from buyers looking for an ABB SPAJ 140 C supplier in India, SPAJ 140 C replacement relay, discontinued ABB SPACOM relay, SPAJ 140 C price or SPAJ 140 C to REX610 retrofit.

ABB SPAJ 140 C Model and Product Status

SPAJ 140 C is a specific ABB relay model, not a product family containing several variants under different model numbers.

It belongs to ABB’s older SPACOM / SPAJ protection relay range.

Related ABB SPAJ models such as:

• SPAJ 141 C
• SPAJ 142 C
• SPAJ 144 C

are separate relay models and should be treated as individual products.

SPAJ 140 C uses the ABB SPCJ 4D29 combined overcurrent and earth-fault relay module.

ABB lists SPAJ 140 C as a non-active product since 2016, making replacement and retrofit enquiries more important than new-project enquiries.

ABB SPAJ 140 C to REX610 Retrofit

ABB provides a retrofit route from several older SPACOM relays to its newer REX610 protection relay, including SPAJ 140 C.

This can be considered where:

• Original SPAJ 140 C availability is difficult
• An old relay has failed
• The switchgear is being modernised
• The plant wants to move away from legacy protection relays
• A long-term replacement solution is required

ABB provides a dedicated retrofit arrangement for moving SPAJ 140 C applications to REX610.

A retrofit should still be checked against the existing:

• CT secondary
• Auxiliary supply
• Protection settings
• Trip wiring
• Signalling contacts
• Blocking signals
• Panel arrangement

For an ABB SPAJ 140 C to REX610 replacement enquiry, send the SPAJ 140 C nameplate and available relay settings. This helps identify the existing protection arrangement before selecting the retrofit.
