■ Application
3KA switch disconnectors are implemented as main control
switches and EMERGENCY-STOP switches for normal switching
duty and isolation of main circuits and auxiliary circuits. Another
field of application is the switching of induction motors and other
loads in the event of maintenance and repair.
Main control and EMERGENCY-STOP switches are manually
operated switch disconnectors according to IEC 60947-3 and
VDE 0660 Part 107 (EN 60947-3) and comply with the conditions
for switch disconnectors and the requirements of the machinery
directive EN 60204-1.
■ Selection and ordering data
All switch disconnectors with degree of protection IP00
Conductor connecting screws are generally included in the scope of supply
1) Rated values reduced in the event of strong harmonics caused by
