TeSys™ IEC-Style Contactors and Starters Selection Guide
Contactor Selection for Utilization Category AC-3
21
01/04
© 2001-2004 Schneider Electric All Rights Reserved
Use in Category AC-3 (Ve
≤ 440 Vac)
Operational power in kW-50 Hz.
Example: Asynchronous motor with P = 132 kW – Ve = 380 V – Ie = 245 A – Ic = Ie = 245 A; or
Asynchronous motor with P = 132 kW – Ve = 415 V – Ie = 240 A – Ic = Ie = 240 A.
1.5 million operating cycles required.
The above selection curves show the contactor rating needed: LC1F330.
Use in Category AC-3 (Ve = 660/690 Vac)
Example: Asynchronous motor with P = 132 kW – Ve = 660 V – Ie = 140 A – Ic = Ie = 140 A.
1.5 million operating cycles required.
The above selection curves show the contactor rating needed: LC1F330.
Control of 3-phase
asynchronous squirrel
cage motors with
breaking while
running.
The current broken
(Ic) in category AC-3
is equal to the rated
operational current
(Ie) of the motor.
Use motor full-load
current on horizontal
axis for selection
purposes.
