Product details

What you're holding

The ABB 1SAZ721201R1043 is a thermal-overload heater element from the 1SAZ721201R family — a snap-in resistive module that lives inside a motor-starter overload relay and trips the auxiliary contact when sustained current heats the bimetal past its trip curve. It sits in the Thermal Overload Heaters for Starters sub-category under Contactors and Starters, so the buyer already knows what they're spec'ing it against — a heater pack matched to a particular amp range on a given ABB overload base.

Frequently asked questions

What is the closest functional second-source to 1SAZ721201R1043?

Inside the same 1SAZ721201R family at the same 0.06 kgs weight, 1SAZ721201R1031 is the like-for-like peer. It's the same product class; the trip current is the deciding spec to confirm before treating it as a drop-in.

What is 1SAZ721201R1043's listed part number?

1SAZ721201R1043 — that's the full ABB order code as carried on the spec line.

What is 1SAZ721201R1043's listed weight?

0.06 kgs on the spec sheet — that's the heater element alone, not the assembled overload relay base it clips into.

Will 1SAZ721201R1043 drop into a panel that was specified around 1SAZ721201R1031 without rewiring?

Both belong to the 1SAZ721201R family at the same 0.06 kgs and the same Thermal Overload Heaters for Starters slot, so the physical mount matches. The trip-current range is the spec that decides whether it's a true swap — confirm that against the motor nameplate before treating it as a drop-in.
