What the order code resolves to
The ABB 1SAZ321201R1006 is filed in the Solid State Overload Relays sub-class under the broader Circuit Breakers, Fuses & Protection heading, and the listing title identifies it as a THERMAL TRIP by ASEA BROWN BOVERI — which is a trip element rather than a complete electronic overload relay assembly.
Where it sits in a panel
Thermal trips in this class are the replaceable trip element that pairs with the matching ABB contactor/overload-relay frame; it carries no separately listed current range or trip class in this spec line, so the buyer matches it back to the same frame it was specified against on the BOM.
Sourcing posture
No production-status entry is on record for this order code, so the part is sourced to order against an RFQ. Specify it by exact code in the BOM and quote to delivery date, carrying the commissioning spares on the same RFQ.
