For most initial enquiries, these details are enough for us to start checking availability.

ARP IMPEX supplies and exports ABB SPAF 140 C frequency relays for replacement and maintenance needs and can also assist with REX615 retrofit requirements.

Description

ARP IMPEX is a supplier and exporter of ABB SPAF 140 C frequency relays for existing power plants, generator protection panels, industrial electrical systems and legacy ABB SPACOM installations.

SPAF 140 C is used for protection against abnormal system frequency. It can provide:

• Underfrequency protection
• Overfrequency protection
• Rate-of-change-of-frequency protection

The relay is commonly found in generator protection panels and other AC systems where equipment needs to be disconnected when frequency moves outside the permitted range.

SPAF 140 C can also be used with large synchronous motors where protection is required during loss of supply or network disturbances.

Most buyers looking for SPAF 140 C today already have the relay installed. They may need an exact spare, a replacement for a failed unit or a modern ABB alternative.

If you have an existing SPAF 140 C, send us the relay nameplate, and we can check the correct version.

ABB SPAF 140 C Replacement with REX615

ABB supports SPAF 140 C through its SPACOM-to-REX615 retrofit program.

The retrofit route can be considered when:

• The original SPAF 140 C is difficult to source
• An installed relay has failed
• Long-term support is required
• The protection panel is being upgraded
• Modern communication is required
• Additional protection and monitoring functions are needed

ABB’s retrofit arrangement helps reduce rewiring when replacing the old SPAF 140 C with REX615.

The existing relay version and panel details should still be checked before the replacement is finalised.

For the retrofit enquiry, send:

• SPAF 140 C nameplate
• Quantity
• Destination country
• Existing panel details, if available

Additional technical information can be shared later if needed.
