Summary of Electrical Auxiliary Devices
The following table shows electrical auxiliary devices that can be added to devices. They can be installed on site. For more information, see the TeSys Motor Control and Protection Components Catalog.
|
Electrical auxiliary device |
Use |
|---|---|
|
OF auxiliary contact |
View the on/off status of the device remotely. |
|
SD auxiliary contact |
View the trip status of the device remotely. |
|
SDE auxiliary contact |
Indicate that the device has tripped on an electrical fault. |
|
AU undervoltage trip release |
Trip the device when the control voltage drops below a tripping threshold. |
|
AS shunt trip |
Send an electrical trip command remotely to trip the device. |
|
