Fault Fiter^® Electronic Power Fuse

Fault Interruption

There are two fundamental modes of operation: the inverse-time mode, and the instantaneous mode that provides current-limiting protection for system equipment and conductors.

The inverse-time mode incorporates special electronic counters that provide an appropriate delayed response based on the fault current magnitude. The TCC can be tailored to meet the special coordination requirements of the application.

The instantaneous mode provides current limitation whenever the rate-of-rise of current exceeds the threshold value determined by the control module.
