Product details

What you're sourcing

The ABB 1SAZ721201R1025 is a thermal overload heater element built for starters, with the auxiliary circuit rated for 600VDC/AC at 50/60Hz — the figure that governs what it sits next to on the panel. It lives in the thermal overload heater family under ABB Contactors and Starters, which means it clips onto the matching starter block and acts as the heater/calibration element that drives the overload's trip curve — not the overload relay itself.

Frequently asked questions

What aux-circuit rating does 1SAZ721201R1025 carry?

The aux circuit is rated 600VDC/AC at 50/60Hz.

Is 1SAZ721201R1025 a drop-in for a panel specified around 1SAZ721201R1049?

Both are ABB thermal overload heater elements in the same family, but they are separate calibration codes — confirm the motor's full-load amp draw against the heater's current range before swapping one for the other on the same starter block.
