What the line shows
The ABB 1SAZ211201R1017 is a solid state overload relay sitting in the Circuit Breakers, Fuses & Protection, Relays, Solid State Overload Relays category, base mounted by ABB and designated BASE MTD on the line card. For motor protection circuits, this class of device carries the solid-state sensing and trip logic for an upstream contactor — current-class, phase-loss and thermal memory functions sit inside the relay head.
Sourcing posture
Specified into the BOM as ABB 1SAZ211201R1017 and quoted to order against an RFQ — the supply posture that fits a drop-ship model where the spread and a clean ship govern more than the part identity itself.
