ABB Overload Relay Cross Reference

This cross-reference page explains how to narrow a replacement for ABB Overload Relay without pretending every nearby part is interchangeable. It keeps the focus on the checks that actually decide whether the replacement can work.

Cross-reference guide

Start with the original family

Cross-reference work on abb overload relay should start with the installed family and application type, not with a keyword search alone.

If the original family is uncertain, capture the nameplate, the surrounding assembly details, and the exact job conditions before comparing anything else.

Common replacement path

The usual path is to identify the original duty, then compare the replacement family on motor FLA, trip class, starter compatibility, reset behavior, and ambient conditions, plus accessories, fit, and certifications.

Family-level mapping table

Use this table as the first narrowing step. It is not a part-number interchange list, but it does show the typical path engineers follow from the installed family into a current family or equivalent platform.

Original family or installed situation Typical current path What to verify before approval
ABB Thermal overload relay Current thermal overload family matched to the starter or contactor platform Confirm trip class, adjustment range, mounting interface, and reset expectations.
ABB Electronic overload relay Current electronic overload family with the same sensing and protection role Check FLA range, phase-loss behavior, control wiring, and communication needs.
ABB Starter-mounted overload assembly Current overload platform approved for the same starter frame The overload has to fit the starter family mechanically and electrically, not just by amp range.

What to verify before substitution

Verify item Why it matters
Original family and installed job Cross-reference work starts with the installed platform and actual duty, not with a loose text search.
Overload relay ratings The alternate has to stay aligned on motor FLA, trip class, starter compatibility, reset behavior, and ambient conditions.
Supporting parts and accessories Trip contacts, reset method, current-setting dial, and starter mounting details can change the replacement path even when the main frame looks close.
Mechanical fit and certifications Mounting, spacing, and approvals can stop a near match from being usable.

When to stop and review the application

Stop treating the job like a simple cross-reference when the duty is severe, the enclosure is unusual, accessories are missing, or the original part markings are incomplete.

Important verification notes

Treat this page as a screening tool. If the ratings, control details, accessories, fit, or certifications stop lining up, pause the substitution and review the original application again before ordering.

What to verify before substitution

Item to verify Why it matters
Original family and application A mismatch here can change performance, fit, safety acceptance, or expected service life.
Voltage and load rating A mismatch here can change performance, fit, safety acceptance, or expected service life.
Control details and accessories A mismatch here can change performance, fit, safety acceptance, or expected service life.
Mechanical fit and wiring space A mismatch here can change performance, fit, safety acceptance, or expected service life.
Certifications and surrounding assembly fit A mismatch here can change performance, fit, safety acceptance, or expected service life.

Compatibility warning

Never assume a cross-reference is a guaranteed drop-in replacement. Always verify coil voltage, amp rating, poles, auxiliary contacts, mounting, certifications, and enclosure or wiring constraints before ordering.
