reference current value is exceeded by the residual current. Dependent on the
characteristic selected and the residual current magnitude the P631 will
determine the tripping time. Moreover the tripping time will under no
circumstances fall below a settable minimum time threshold irrespective of the
residual current flow magnitude.
The inverse-time stage can be blocked by an appropriately configured binary
signal input. In addition the inverse-time stage can also be automatically blocked
by singlepole or multi-pole starting (depending on the setting).
