Special functions
• With regard to the setting of the protection parameters it is possible to carry out several tests
using different thresholds and curves to identify the optimum program for the circuit breaker/
installation.
• The test unit can memorise a special "frequent use" program for each of the protection units
that may be electronically programmed (Define default).
• The manual test function also enables a general current to be introduced into the release in
order to test the trip time (a particularly useful function for selectivity studies between two or
more circuit breakers).
