SIMARIS curves

Visualization and evaluation of characteristic curves with SIMARIS curves: easy and fast

The SIMARIS curves software, which also comes free of charge, visualizes characteristic curves with tolerance bands as well as setting options of specific parameters for low-voltage protective devices and fuses (IEC). Characteristic cut-off current and let-through energy curves are also displayed. Practical advantage: You can save selected tripping curves as favorites or overall project!

SIMARIS Software Free of Charge

You want to visualize and evaluate the characteristic tripping curves of Siemens low-voltage protective devices and fuses (IEC) quickly and easily without creating a new project in SIMARIS design? This is precisely what the free SIMARIS curves software does for you.


The free tool SIMARIS curves in 20 languages for planning electrical power distribution - just download from this site.


SIMARIS curves enables viewing several characteristic tripping curves in parallel and also simulating parameter settings for protective devices.* To display characteristic curves, select appropriate products by directly entering the Siemens order number, or use the convenient catalogue selection based on technical device data.


This tool also facilitates the saving of individual products with freely definable attributes as favorites and their call-up via a click. In addition to tripping characteristics with tolerance ranges and possible parameter adjustments, also cut-off current and let-through energy characteristic curves are offered, depending on the device type. A clearly structured printout documents the selected characteristic curves and their respective settings. Take a closer look at the functions of SIMARIS curves!


* We recommend to use SIMARIS design professional for selectivity evaluation.
