The 1SAZ211201R1028: Solid-state overload relays in this class replace the older bi-metallic thermal units on three-phase motor starters — the electronics give a tighter trip curve, phase-loss sensitivity, and a usually wider current setting range without swapping the heater element. In a control panel that means the relay is wired into the contactor coil circuit on its NC output and feeds the motor lines through its current transformers on the line side.
The closest ledger-listed peer is 1SVR430711R0300, which shares the same Relays / Solid State Overload Relays class and the same 0.07 kgs spec-line weight, but no current-range, pole, or terminal data is recorded for either part, so confirm the trip-class range and line-side arrangement before treating it as a drop-in alternate.
The listed part number is 1SAZ211201R1028, sold under the ABB brand on the Solid State Overload Relays sub-category of the Relays class.
The spec line lists 1SAZ211201R1028 at 0.07 kgs.
