Minicontactors
CI 5-
CI 5- minicontactors cover the power range up to
5.5 kW and are available for AC and DC coil
voltages enabling reliable working with
extremely low and high voltage uctuations.
Characteristic of the minicontactors is that they
are compact and suitable for applications where
space is at a premium. With add-on auxiliary
contact blocks, timers and other additional
accessories they oer high exibility.
One of the most important features is status
feedback provided by mechanically linked and
mirror contact performance in conrmity with
IEC 60947-4-1 and 60947-5-1.
Additionally the CI 5- ensures safety against
electric shock by extra protective distance
between housing surfaces and live parts.
The CI 5- programme includes dedicated
bimetallic overload protection relay with a
dierential mechanism for sensitivity to phaseloss conditions.
Features • Compact design
• High exibility
• Power range up to 5.5 kw
• For ac and dc coil voltages

Thermal overload relay
TI 9C-5
Ordering
Introduction
Thermal overload relay TI 9C-5 is used with
minicontactor CI 5- for protection of squirrel cage
motors where compactness is required. The relay have
single – phase protection, i.e. accelerated release if
phase drop-out occurs.
This is particularly important for motors with delta
connected windings.
Other features of TI 9C-5 :
• Stop / reset button
• Manual / automatic reset
• Test button
• Double scale for direct start or Y/D start
• Galvanically isolated signal contact

Coordination type 1: Any type of damage to the motor starter is permissible. If the motor starter is in an enclosure, no external
damage to the enclosure is permissible. After a short- circuit the thermal overload relay shall be partially or
wholly replaced.
Coordination type 2: No damage to the motor starter is permissible, but slight contact burning and welding is permissible.

Selection of thermal overload relay:
The selection of a thermal overload relay must be based
on the motor full load current and the method of
starting:
- With direct start range for motor starter is used
- With star – delta start the range for Y/D starter is
used
Example:
Full load current: 12A
- With direct start the suitable motor starter
range is 8.0 – 12A, i.e. thermal overload relay
047H3141
- With Y/D – start, the suitable motor starter
range is 10 – 16A, i.e. thermal overload relay
047H3140
