Product details

Where it lives in a panel

The 1SAZ811201R1003: A SSOLR of this class sits downstream of the contactor on a motor branch — it measures phase current through internal CTs, models the motor's heating curve in firmware, and trips the contactor's coil via the NC contact when the model crosses the trip threshold. That makes it the thermal-trip element in an across-the-line starter, paired with a short-circuit protective device (a manual motor protector or breaker) ahead of it for the bolted-fault zone, which is where the selectivity and SCCR coordination work is done at the panel level.

Frequently asked questions

What part number is on this Solid State Overload Relay line?

1SAZ811201R1003 — ABB, filed as a Solid State Overload Relay under Circuit Breakers, Fuses & Protection → Relays.

Will 1SAZ811201R1003 drop into a panel that was specified around 1SNA645022R2700 without rewiring?

The evidence doesn't carry pinout or terminal-compatibility data for either MPN, so a no-rewire swap isn't asserted here — confirm against the panel drawing before specifying.
