■
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.
