Product details

Part identity and class

The ABB 1SAZ721201R1051 is catalogued as a Solid State Overload Relay, sitting under Circuit Breakers, Fuses & Protection › Relays in the same line that holds electromechanical and solid-state motor protection devices. Solid-state overload relays of this class replace the bimetallic strip in a conventional thermal overload with an electronic current-sensing and trip element, so the cubicle builder gets a tighter, adjustable trip class and a clean auxiliary output back to the contactor coil and the PLC.

Frequently asked questions

When sourcing 1SAZ721201R1051, what is the closest functional second source — 1SNA645022R2700?

1SNA645022R2700 sits in the same Solid State Overload Relays sub-category, but the evidence does not record shared electrical ratings or a common footprint, so it cannot be presented as a verified drop-in alternate without checking the device nameplate against the original motor-starter specification.

What is 1SAZ721201R1051's listed weight on this Solid State Overload Relays line?

Weight is listed as 0.00 kgs — a catalogue placeholder rather than a handling figure; the device is a DIN-rail or contactor-mounted electronic module, so mass does not drive the selection.
