Static type over current relay K2CA-D type, attention to the protection of the coordination oof static type OCR D4N-2B20R.
The prootection coordination between OCR and MCCB is simple .
1 sets of three-phase protection, can save space and manpower.
Compared with the plate movement start display, through time display, make maintenance and inspection becomes simple.
The display oof the accident occurrence phase is used to facilitate the inspection after the accident D4N-2B20R.
Reduce the consumption of VA, reduce the burden of converter.
