<strong>TeSys</strong> contactors<br />
For utilisation category AC-3<br />
Use in category AC-3 (Ue ≤ 440 V)<br />
Control of 3-phase<br />
asynchronous motors<br />
with breaking whilst<br />
running.<br />
The current broken (Ic)<br />
in category AC-3 is<br />
equal to the rated<br />
operational current (Ie)<br />
of the motor.<br />
Millions of operating cycles<br />
Current broken in A<br />
Operational power in kW-50 Hz<br />
Example<br />
Asynchronous motor with P = 5.5 kW -Ue =400 V-Ie =11 A - Ic = Ie =11 A<br />
or asynchronous motor with P = 5.5 kW -Ue = 415 V-Ie =11 A-Ic = Ie = 11 A<br />
3 million operating cycles required.<br />
The above selection curves show the contactor rating needed: LC1-D18.<br />
Use in category AC-3 (Ue =660/690 V) (1)<br />
Control of 3-phase<br />
asynchronous motors<br />
with breaking whilst<br />
running.<br />
The current broken (Ic)<br />
in category AC-3 is<br />
equal to the rated<br />
operational current (Ie)<br />
of the motor.<br />
Millions of operating cycles<br />
Current broken in A<br />
(1) For Ue = 1000 V use the 660/690 V curves, but do not exceed the operational current at the operational power<br />
indicated for 1000 V.<br />
