Area of application
SENTRIC KA switch disconnectors are implemented as main
control switches and EMERGENCY-STOP switches for normal
switching duty and isolation of main circuits and auxiliary cir-
cuits. Another area of application is the switching of three-phase
induction motors and other loads for maintenance and repair
work.
Main control switches and EMERGENCY-STOP switches are
hand-operated switch disconnectors acc. to IEC 60947-3 and
VDE 0660 Part 107 (EN 60947-3) and comply with the isolation
conditions and the requirements of machine guideline
EN 60204-1.

Selection and ordering data
All switch disconnectors to the IP00 degree of protection
Conductor connecting screws are generally included in the scope of supply.
1) The nominal values are reduced in the case of strong harmonics due to fre-
quency converter operation.
