ABB RB122G-24VUC Industrial Electrical Control Relay

The ABB RB122G-24VUC is an electrical control relay supplied by ABB, a globally recognized manufacturer of electrical and industrial control components. Supplied as a single unit (1 each), it gives contractors, panel builders, and facility maintenance teams a straightforward way to stock, replace, or specify this exact part. The listing is identified by its precise manufacturer model designation, RB122G-24VUC, so it can be cross-referenced directly against existing panel schedules or bills of material. Complete technical specifications, ratings, and dimensional data are published in the manufacturer's official spec sheet, available for review prior to specification or installation.

Key Features

  • Model Designation: The RB122G-24VUC part number allows precise cross-reference and reordering for replacement or new-build projects.
  • Packaging: Supplied 1 each, suitable for individual stocking, spot replacement, or maintenance-on-demand purchasing.
  • Manufacturer Backing: Produced by ABB, a widely recognized manufacturer of electrical and industrial control components.
  • Manufacturer Documentation: A published spec sheet is available for detailed technical review prior to specification, quoting, or installation.
  • Procurement Compliance Records: Country-of-origin and federal procurement compliance data (ARRA, BAA) are maintained on file to support government and institutional purchasing requirements.
  • Single-Part Traceability: The exact model designation supports accurate cross-referencing against existing panel schedules or bills of material.

ABB 1SNA645012R2500 – Frequently Asked Questions

1) What order number do I use for the ABB RB122G-24VUC relay?
ABB's model designation is RB122G-24VUC, and the orderable ABB catalog number is 1SNA645012R2500. Panel schedules and bills of material usually carry the RB122G-24VUC designation, so cross-reference the two when you quote or reorder to be sure you are pulling the same part.
2) Is the Square D CAD32G7 a drop-in replacement for the ABB RB122G-24VUC relay?
No, they are not interchangeable as-is. The Square D CAD32G7 is a TeSys Deca control relay with a 3 NO + 2 NC contact arrangement and a 120 VAC coil. The ABB RB122G-24VUC carries a 24VUC coil designation in its model number, meaning it is built for a 24 V universal (AC or DC) control circuit. Swapping a 120 VAC coil device into a panel wired for 24 V control, or the reverse, requires rewiring the control circuit, so confirm the coil voltage on your panel schedule before substituting. Contact layout should also be matched against the ABB spec sheet.
3) Does the ABB RB122G-24VUC come as a single relay or in a multi-pack?
It ships as a single unit, 1 each. That suits spot replacement in an existing panel or holding one or two on the MRO shelf; for a new panel build where you need a dozen identical relays, order by the quantity you need rather than expecting a bulk pack.
4) Where do I get the contact ratings and dimensions for the ABB RB122G-24VUC before I lay out my panel?
ABB publishes an official spec sheet for the RB122G-24VUC, and that document is the source for ratings and dimensional data. Pull it before you finalize DIN rail layout or wire sizing rather than working from the model designation alone.
5) Is there an alternative control relay if I need multiple contacts and a 120 VAC coil instead?
For a 120 VAC coil with a multi-pole contact block, the Square D TeSys Deca control relay with 3 NO + 2 NC contacts is the option to look at. It is a different platform from the ABB RB122G-24VUC, so it will not drop into the same terminal or rail arrangement, but it covers the 120 VAC control-circuit case directly.
6) What is the difference between the ABB RB122G-24VUC and a TeSys Deca control relay?
They are both panel-mount control relays but they come from different manufacturer families. The RB122G-24VUC is ABB's part, ordered under ABB catalog number 1SNA645012R2500, with a 24 V universal coil designation and manufacturer spec sheet published for contact and dimensional data. The Square D CAD32G7 belongs to the TeSys Deca series and is specified as 3 NO + 2 NC with a 120 VAC coil. Accessory blocks, mounting adapters, and spare contact blocks follow each maker's own series, so a panel standardized on one family generally stays on that family for spares.
7) We are standardizing relay spares across a facility - does it matter if I mix ABB and Square D control relays in the same panel?
Electrically they can coexist if each is wired to the coil voltage it is built for, but for a stocking program the practical issue is spares. The ABB RB122G-24VUC is carried under one ABB catalog number, 1SNA645012R2500, while the Square D CAD32G7 sits in the TeSys Deca series with its own accessory and contact-block ecosystem. Standardizing on a single family means one set of part numbers on the shelf and one coil voltage convention across the control circuits, which is usually the deciding factor for MRO buyers rather than any performance difference.
8) What kind of device is the ABB RB122G-24VUC, and where does it get used?
It is an electrical control relay, the interposing/switching type used inside industrial control panels, automation and process control systems, OEM equipment, and panel retrofits. Typical role is taking a low-power control signal and switching a separate load circuit.
9) Can I get country-of-origin and Buy American documentation on the ABB RB122G-24VUC for a government job?
Country-of-origin and federal procurement compliance records (ARRA and BAA) are maintained on file for this ABB relay, which is what institutional and government buyers typically need attached to a submittal package.
