1.1.1 Introduction
The MCD 100 soft starters are designed for soft starting
and stopping of 3 phase a.c. motors, thus reducing the
inrush current and eliminating the damaging effects of
high starting torque surges.
The digitally controlled soft starter features accurate
settings and easy installation. The controller has
individually adjustable acceleration and deceleration times.
Thanks to the adjustable initial torque and the unique
breakaway (kick start) function the soft starter can be
optimized for almost any application.
The MCD 100 soft starters are typically used on motor
applications where a smooth stat and/or stop is
advantageous, such as conveyors, fans, pumps,
compressors and high inertia loads. MCD 100 soft starters
are also obvious as replacement for star/delta starters.
