Circuit Breaker Identification Data

The circuit breaker is identified by the following data:

  • Rated current

  • Protection type

  • Number of IO modules connected

  • Additional data according to the range of the circuit breaker

Circuit Breaker Health Status

The health status of the MasterPact MTZ drawout circuit breaker is indicated by one of the following icons:

Drawout Circuit Breaker Position in the Cradle

The position of the drawout circuit breaker in the cradle is indicated by the following icons:

Icon

Description

Drawout circuit breaker is in connected position.

Drawout circuit breaker is in test position.

Drawout circuit breaker is in disconnected position.

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:

  • Remote control: The control buttons on the webpage can be used to control the circuit breaker remotely.

  • Local control: The control buttons are not available on the webpage. The circuit breaker is controlled locally through manual operation.

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 Buttons

When the circuit breaker is in remote control mode, the following control buttons are available:

Control Button

Description

Click the button to open the circuit breaker.

Click the button to close the circuit breaker. The circuit breaker will close only if it is ready to close.

For each control action:

  • A safety message is displayed in a pop-up window.

    • Read the message and click I understand to confirm the action.

    • Click Cancel to cancel the action.

    • The result of the action (successful or failed) is displayed in a pop-up window.

NOTE: Pop-up message confirms that the command is successfully sent or not. It does not confirm whether the complete action is successful.

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 MasterPact MTZ drawout 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.
