CI-tronic™ single-phase compressor soft starter,
Type TCI 25C

The TCI 25C soft starter is designed for soft
starting of single-phase compressors. During
start the TCI 25C will gradually ramp-up the
motor voltage to full line voltage thus reducing
the starting current peak.

Features • Easy installation between normal motor starter

and motor

• LED status indication

• Unlimited start/stop operation per hour

• DIN rail mountable

• Starting time max. 0,5 seconds

• Suitable for 50/60 Hz

• EN 60947-4-2

• CE, EAC, LLC CDC TYSK

As soon as the TCI 25C is connected to mains
voltage a motor soft start is performed.
The balanced ramp-up time and starting voltage

TCI 25C can be used for single phase motors
with and without a start capacitor - see wiring
examples.

(initial torque) ensures a fast and reliable start.
