CI-tronic™ Soft start motor controller

MCI 3, MCI 15, MCI 25, MCI 30 I-O, MCI 40-3D I-O and MCI 50-3 I-O

The MCI soft starters are designed for soft starting and stopping of 3 phase AC 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 MCI soft starters are typically used on motor applications where a smooth start and/or stop is advantageous, such as conveyors, fans, pumps, compressors and high inertia loads. MCI soft starters are also obvious as replacement for star/delta starters.

• Acceleration times adjustable: 0 – 10 seconds, MCI 3, MCI 15 and MCI 25 0 – 20 seconds, MCI 30 I-O 0 – 30 seconds, MCI 40-3D I-O, MCI 50-3 I-O

• Deceleration times adjustable: 0 – 10 seconds, MCI 3, MCI 15, and MCI 25 0 – 20 seconds, MCI 30 I-O 0 – 60 seconds, MCI 40-3D I-O, MCI 50-3 I-O
