Product details

The 1SAZ431201R1001: Solid state units of this class replace thermal bimol strips with a current-transformer front end and an electronic trip curve, so the question for the maintenance planner is the failure mode — drift in the sensing loop or a tripped output that won't reset — not contact welding, and that changes the spare-parts posture compared to a thermal overload on the same contactor frame.

Frequently asked questions

Will 1SAZ431201R1001 drop into a panel specified around 1SVR430710R0200 without rewiring?

Both sit in the same solid state overload relay class, but 1SAZ431201R1001 is listed at 0.45 kgs versus 0.36 kgs for 1SVR430710R0200, so the DIN footprint and the line-side bend room need to be checked against the ABB datasheet before treating it as a like-for-like swap.
