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.

For selection of capacitors and start relay, please refer to recommendations from the compressor
manufacturer
If the ambient temperature exceeds 40 °C the current must be de-rated according to table below.

Overheat protection
If required the controller can be protected
against overheating by inserting a thermostat in
the slot on the right-hand side of the controller.
Order: UP 62 thermostat 037N0050
The thermostat is connected in series with the
control circuit of the main contactor. When the
temperature of the heat sink exceeds 100 °C the
main contactor will be switched OFF. A manual
reset is necessary to restart this circuit.
Mounting instructions
Dimensions
[mm] (inch)
The controller is designed for vertical mounting.
If the controller is mounted horizontally the load
current must be reduced by 50%.
The controller needs no side clearance. Clearance
between two vertical mounted controllers must
be minimum 80 mm (3.15”).
Clearance between controller and top and
bottom walls must be minimum 30 mm (1.2”).
