ABB 1SAZ211201R2017 — Class 10A overload relay
The ABB 1SAZ211201R2017 is a Class 10A thermal overcurrent relay in the Relays › Overcurrent Relays slice of the protection catalog, sitting under a contactor as the overload element of a motor starter. The Class 10A designation is the trip-class rating carried on the listing.
What Class 10A means for the BOM line
Class 10A is the workhorse curve on this part family for standard induction motor duty. For a high-inertia load, a higher trip class is the usual pick. The current range stamped on the relay front is what selects the actual overload element, not the relay's own order code. Verify the heater range matches motor FLA before quoting.
Sourcing posture
No production-status entry is on file for 1SAZ211201R2017, so the part's lifecycle position is not being asserted here. The qualitative supply posture is quoted to order against an RFQ — specify the heater current range and trip class with the line, and the BOM slot can be filled from the authorized channel or the surplus market depending on the result.
