Static type reverse electric relay K2FW type.
Ensure high accuracy digital UFR/OFR.
Constitute by the crystal oscillator plus digital IC,
Can achieve high accuracy of frequency detection (adjustment, detection accuracy of less than 0.1HZ).
50-60HZ share, can be adjusted arbitrarily in the range of 45-65HZ through the surface of the dial switch plate OMRON K3HB-VLC-EBCD1 AC100-240 PDF datasheet.
Because of the high speed detection, the low frequency relay can detect the system accident before the under voltage relay K3HB-VLC-EBCD1 AC100-240 Appearance: there are F4 shell, R2 shell.

Static type over current relay K2CA-D type, attention to the protection of the coordination of static type OCR.
The protection coordination between OCR andd MCCB is simple K3HB-VLC-EBCD1 AC100-240 PDF catalog.
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 K3HB-VLC-EBCD1 AC100-240 PDF catalog.
Reduce the consumption of VA, reduce the burden of converter.
