Static type over current relay K2CA-D type, attention to the protection of the coordination of static type OCR.
The protection 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 of the accident occurrence phase is used to facilitate the inspection after the accident.
Reduce the consumption of VA, reduce the burden of converter. Illumination: Non-lighted.
Pushbutton color: Yellow.
Pushbutton size: 30 dia.
Terminal: Solder terminal.
Contact form: TPST-NC.
Separate Construction with Smallest.
Class of Depth in the World.
Direct opening mechanism to open contacts in emergencies,
such as when they are welded.
Conforms to EN 60947-5-5.
Includes a safety lock to prevent misuse.
Features separate construction that allows the Switch to be,
separated for easier wiring and one-piece construction that,
allows easier handling.
Models available with 3 contacts built into a single block (A165E-U).
