122 Power Xpert C445 Global Motor Management Relay MN042003EN—January 2019 www.eaton.com
Example #1
Mains voltage returns above Voltage Return Level setting in
<200 ms (default) ~ 12 Cycles.
Contactor re-closes and motor restarts automatically with no
time delay. This is accomplished by holding the start-circuit
aux relay closed during the Auto Time voltage loss duration.
Note: In the event of very short voltage drops, the contactor
may or may not open. This is dependent on contactor
specifications and power to the coil.
