The product code ABB S30JBK-ZT-30R3G-4889G does not correspond to a standard, publicly documented ABB automation or power product in widely available catalogs (such as AC 500. AC 800M, System 800xA, or low-voltage switchgear lines). Based on ABB’s typical naming conventions, this appears to be either:

A custom-configured or customer-specific part number, possibly for a panel, enclosure, terminal block assembly, or interface kit;

An internal manufacturing or project-specific identifier (e.g., for a skid, junction box, or wiring harness);

A misread or transcribed variant of a standard ABB product (e.g., confusion with S30 series terminal blocks or JBK junction boxes).

Analysis of the Code Structure:

S30: May refer to ABB’s S30 series terminal blocks (part of the Pluggable Terminal Block family), commonly used for signal and power distribution.

JBK: Often stands for Junction Box Kit in industrial contexts.

ZT-30R3G: Suggests customization—possibly “ZT” = special version, “30R3G” = 30-position, 3-row, green housing or grounding variant.

4889G: Likely a batch, revision, or customer-specific suffix (e.g., for a project like “Project G4889”).

However, no official ABB datasheet, catalog entry, or technical manual currently lists S30JBK-ZT-30R3G-4889G as a standard commercial product.

Recommended Actions:

✅ 1. Verify the Part Number

Check labels, packaging, or engineering drawings for typos.

Common similar ABB products include:

ABB S30 series terminal blocks: e.g., S30-30/3-G (30-pole, 3-level, green)

ABB JBK enclosures: e.g., JBK-4889 (custom junction box)

ABB ACH550/ACH580 drive accessories (less likely)

✅ 2. Contact ABB Support or an Authorized Distributor

Provide the full code and context (e.g., application: turbine control, panel wiring, etc.). ABB often uses extended suffixes for:

Custom color coding

Pre-wired assemblies

Project-specific certifications (e.g., marine, hazardous area)

✅ 3. If Used in a Control Panel

This may be a panel builder’s internal part number referencing an ABB-based assembly (e.g., a terminal block rail with fuse holders, grounding bars, and labeling per project spec 4889G).

Possible Interpretation (Best Guess):

ABB S30JBK-ZT-30R3G-4889G likely refers to a custom junction terminal block assembly based on the S30 pluggable terminal system, configured as:

30 positions

3 rows (R3)

Green (G) insulated or marked terminals

Packaged in a junction box (JBK)

Built for customer/project 4889G

But this is not a standard off-the-shelf ABB product.

Next Steps:

If you require:

Replacement: Provide a photo of the physical unit and its wiring.

Datasheet: Request documentation from the original equipment manufacturer (OEM) or panel builder.

Equivalent: We can suggest standard ABB S30 terminal blocks (e.g., S30-12/3-G, S30-FUSE) that may serve the same function.
