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 fluctuations.
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 offer high flexibility.
One of the most important features is status feedback provided by mechanically linked and mirror contact performance in confirmity 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 differential mechanism for sensitivity to phaseloss conditions.

Thermal overload relay |
Introduction |
TI 9C-5 |
|
|
|
|
|
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
