Line card note
The 1SAZ211201R1040: The order-code label is carried under the ABB imprint, while the legacy vendor string reads ASEA BROWN BOVERI — the same device, older wording, useful when reconciling a PO line against a vintage packing slip.
Sourcing posture
The part is listed under ABB as a solid-state overload relay SKU. No active or phased status flag is carried on the record, so supply runs quote-to-order through an RFQ until that changes.
Where this part sits on the panel
Solid-state overload relays in this family are the electronic motor-protection module that replaces a thermal bimetallic unit — same panel cut and same line/load conductor path, but the trip curve and current setting are configured at the device rather than by heater element. Specifying 1SAZ211201R1040 into a BOM therefore commits the panel to an electronic, DIP- or rotary-set overload adjacent to the contactor.
