Characteristics Program for
Short-Circuit and Overload Protection Devices

Simple characteristic curve visualisation, comparison and documentation

The characteristics program available free of charge enables setting-specific representation of tripping characteristic of several protective devices on the same time and current scales.

The software makes discrimination between Moeller NZM and IZM circuit-breakers as well as low-voltage h.b.c. fuses significantly easier. Matching of the tripping behaviour of the circuit-breaker to the motor start-up characteristic is also supported.

Characteristics program for circuit-breakers

Within a given frame size, the accessories for circuit-breakers and switch-disconnectors are identical.

You can download the characteristics program free-of-charge. Simply complete the registration form first, then you will receive the current program version.
