Using ABB 1SBH143001R8122 in the correct assembly

This field-service FAQ identifies ABB 1SBH143001R8122 for accurate ordering and for checking the complete installed function.

Verified technical parameters

Use the ABB 1SBH143001R8122 values together with the cited ABB publication and the delivered device marking; option-dependent details require confirmation.

What does this exact code identify?

ABB 1SBH143001R8122 designates 24 V DC auxiliary contactor relay. Quote the whole order code from the installed marking; a family name or similar photograph does not confirm the fitted supply, contact pattern or current window.

The intended ABB 1SBH143001R8122 role is to operate the documented DC control relay position. Check the host machine and approved drawings before deciding whether this is the correct part.

Which technical limits should be compared?

Compare the ABB 1SBH143001R8122 data table with the site design, including current, voltage, trip class, poles or interface where applicable. Values for a sibling order code are not automatically values for this unit.

For ABB 1SBH143001R8122, verify 24 V supply, contact map and suppression. If a required characteristic is not documented, request the manufacturer sheet and inspect the delivered nameplate.

What is normally supplied separately?

ABB 1SBH143001R8122 may rely on an external overload element, mounting kit, auxiliary block, controller settings or host contactor according to its function. List every required companion article in the purchase order.

Do not assume ABB 1SBH143001R8122 includes a complete starter or a ready-to-use safety function. Confirm terminals, accessories, wiring and the whole assembly before installation.

How should a replacement be assessed?

When a supplier suggests another code in place of ABB 1SBH143001R8122, compare the exact series, mounting, dimensions, control supply, load rating, contact pattern and approvals. Get a written technical difference record.

Retain the removed ABB 1SBH143001R8122 and its connection photograph until the replacement has passed the approved functional test. Engineering approval is required for a meaningful change.

What should the technician test?

After isolated installation of ABB 1SBH143001R8122 by qualified personnel, prove all contacts and release. Record test settings, measured values and expected response before returning the circuit to operation.

ABB 1SBH143001R8122 should be tested in normal, commanded and relevant fault or off conditions. Verify feedback signals and interlocks at the system level.

What should purchasing keep on file?

Save the ABB 1SBH143001R8122 code, manufacturer reference, accepted configuration and dated as-left photos with the equipment record. This preserves a reliable route for the next procurement cycle.

If ABB 1SBH143001R8122 becomes obsolete, seek an ABB-supported successor or documented equivalent and review all interface differences; do not silently swap an adjacent variant.
