Drawout Circuit Breaker Position in the Cradle
The position of the drawout circuit breaker in the cradle is indicated by the following icons:
Circuit Breaker Main Contact Position
The position of the main contacts of the circuit breaker is indicated by the following icons:
Icon |
Description |
---|---|
The main contacts of the circuit breaker are closed. |
|
The main contacts of the circuit breaker are opened. |
|
The main contacts of the circuit breaker are opened and the circuit breaker is tripped. The circuit breaker must be reset. |
|
The circuit breaker position is unknown in case of contact position discrepancy. |
Circuit Breaker Control Mode
The circuit breaker control mode is:
The circuit breaker control status is indicated by the following icons:
Icon |
Description |
---|---|
The closing spring is charged and the circuit breaker is ready to close. |
|
The closing spring is charged and the circuit breaker is not ready to close. |
|
The closing spring is discharged and the circuit breaker is not ready to close. |
Close inhibition indicates that the circuit breaker closing is inhibited by the EcoStruxure Power Commission software or IO modules or a remote controller through the communication network.
Circuit Breaker Control Options
When the circuit breaker is in remote control mode, the following control options are available:
Control Options |
Description |
---|---|
Click this option to open the circuit breaker. |
|
Click this option to close the circuit breaker. The circuit breaker will close only if it is ready to close. |
|
Click this option to reset ComPacT NSX or PowerPacT H-, J-, and L-frame circuit breakers. |
For each control action:
-
A safety message is displayed in a pop-up window.
-
Read the message and click
to confirm the action. -
Click
to cancel the action. -
The result of the action (successful or failed) is displayed in a pop-up window.
-
Measurements
The list of measurements displayed depends on the type of MicroLogic of the circuit breaker.
Measurement are shown in the following order:
-
Real time measurements with minimum and maximun values. For circuit breaker, the time stamp of the minimum and maximum values is also displayed.
-
Energy measurements
-
Demand measurements
The minimum and maximum values of the energy and the demand measurements can be reset by users with Installer or Engineer role.
