Contact for Availability
ABB TF42-5.7 (1SAZ721201R1038) is listed as a Thermal Overload Relay, 4.2-5.7A range. The family reference is TF42. This page is intended for exact-reference procurement and replacement review, not for treating nearby catalog codes as automatic substitutes.
The visible catalog descriptor records 4.2-5.7A. Before a purchase order, buyers should match current adjustment range, trip class, reset method, and phase-loss behavior, then confirm direct mounting compatibility with the paired contactor. Any value not shown here must be checked against the manufacturer datasheet or the installed-unit nameplate.
Price, availability, condition, test evidence, lead time, warranty period and export paperwork are quote-specific. A manager confirms those commercial fields after quantity, destination and required delivery window are known.
Exact-Match Checkpoints
Match current adjustment range, trip class, reset method, and phase-loss behavior.
Confirm direct mounting compatibility with the paired contactor.
Verify auxiliary contacts, manual or automatic reset, and temperature compensation.
Check coordination tables for the installed motor starter.

Typical Use Cases
- Motor overload protection.
- Starter-panel maintenance.
- Contactor and relay coordination.
HS and Export Review
The working product function is thermal or electronic overload protection relay. A fixed HS code is not asserted because classification can change with configuration, origin, destination, and broker interpretation. Confirm invoice description, origin evidence, packing data, and destination restrictions during the quote.
Condition, Testing, and Warranty Scope
- Require the quote to state whether the offered unit is factory-new, new surplus, refurbished, used, or another documented condition.
- Ask which visual, marking, packaging, continuity, functional, or bench checks are available for this overload protection relay.
- Record the warranty period, start point, exclusions, return route, and evidence required for a claim.
- Do not release the PO until the condition and test scope match the maintenance plan and installation risk.
RFQ Evidence Checklist for TF42-5.7 (1SAZ721201R1038)
- Send the complete reference TF42-5.7 (1SAZ721201R1038), quantity, destination, deadline, and acceptable split-delivery window.
