4.1.2.6 MCR make-break and overstep tripping (optional)
Make-break and overstep tripping protections are parts of back-up functions, which are optional. They
are both instantaneous tripping actions whose tripping value relate to their service breaking and ultimate
breaking capacities. Usually, MCR current is 40KA, 60KA, 80KA, overstep tripping current is 50KA, 75KA,
100KA(especially for
Type DW40,45,48 breaker, the factory defaults of current values are 40/50KA for Frame
I, 60/75KA for Frame II, 80/100KA for Frame III). Fault current signal sends out tripping instruction directly by
hardware comparison circuit. MCR make-break protection works only at the moment of making (about 100
ms), while overstep tripping is available all the time.
4.1.2.7 System clock adjustment function (
optional)
The controller can be added function of system clock adjustment, to record time and date when the fault
generated. This function automatically eectiveness once is chosen. Details of the function of system clock
adjustment considering chapter7.2.3.5
4.1.2.8 Signal contact output function (optional)
The controller output 4 groups of signal separately, this function realized by programmer or
other special ways.
The provided signal contacts output function and output time indicated as table 7.
Defaulted states of the controller's 4 groups signal contacts output function indicated as table 8.

Outputting at beginning of protection or
