XF, MX, and MN voltage releases are optional accessories mounted inside the device. They can be of standard type, reinforced type, or communicating type:
-
Standard voltage releases are designed to receive either pulse-type or maintained voltage operating orders. For installation information, consult instruction sheet 51156123AA on the Schneider Electric website.
-
Reinforced voltage releases sustain overvoltage on coil control at 15% of control nominal voltage. They are used for electrical networks with a high overvoltage level. For installation information, consult instruction sheet NVE40749 on the Schneider Electric website.
-
Communicating voltage releases are reinforced voltage releases designed to receive opening and closing orders from the wired communication network. For installation information, consult instruction sheet NVE40766 on the Schneider Electric website.
XF Closing Voltage Release
The XF closing voltage release closes the circuit breaker instantaneously when powered if the spring mechanism is charged. The minimum duration of the pulse operating order must be 200 ms.
The XF closing voltage release is available in the standard, reinforced, or communicating type.
MX Opening Voltage Release
The MX opening voltage release opens the circuit breaker instantaneously when powered. The minimum duration of the pulse operating order must be 200 ms. The MX opening voltage release locks the circuit breaker in the OFF position if the command is maintained.
The MX opening voltage release is available in the standard, reinforced, or communicating type.
MN Undervoltage Release
The MN undervoltage release instantaneously opens the circuit breaker when its supply voltage drops to a value between 35% and 70% of its rated voltage. If there is no supply to the release, it is impossible to close the circuit breaker, either manually or electrically. Any attempt to close the circuit breaker has no effect on the main contacts. Circuit breaker closing is enabled again when the supply voltage of the release returns to 85% of its rated value.
The MN undervoltage release is available in the standard or reinforced type.
PF Ready-to-close Contact
This is an optional accessory that is mounted inside the circuit breaker.
The PF ready-to-close contact delivers remotely, the indication delivered locally by the ready-to-close indicator.
It consists of a changeover contact indicating remotely that the circuit breaker is ready to close, that is:
-
The circuit breaker is in the open position.
-
The spring mechanism is charged.
-
There is no maintained opening order.
For information on installation, consult instruction sheet NVE35466 on the Schneider Electric website.
MCH Gear Motor
This is an optional accessory that is mounted inside the circuit breaker.
The MCH gear motor automatically charges the spring mechanism when the circuit breaker is closed, allowing instantaneous closing of the circuit breaker following opening.
For information on installation, consult instruction sheet NVE35483 sheet on the Schneider Electric website.
RES Electrical Remote Reset
This is an optional accessory that is mounted inside the circuit breaker.
Following tripping, this function resets the SDE fault-trip indication contact and the mechanical indicator, and enables circuit breaker closing.
The use of an XF closing release is compulsory with this option.
The RES electrical remote reset is not compatible with the SDE2 additional fault-trip indication contact because they are installed in the same physical location.
For information on installation, consult instruction sheet NVE35503 on the Schneider Electric website.
CDM Mechanical Operation Counter
This is an optional accessory that is mounted inside the circuit breaker.
The CDM mechanical operation counter counts the number of operating cycles and is visible on the front panel. It is compatible with manual and electrical control functions.
This option is compulsory for all source-changeover systems.
For information on installation, consult instruction sheet NVE35485 on the Schneider Electric website.
BCIM Breaker Communication and Isolation Module
This is an optional accessory which is mounted on the back of the MicroLogic Active control unit.
The BCIM module is connected to the XF and MX communicating voltage releases in order to provides the means to remotely control the operation of the circuit breaker. It enables communication between the MicroLogic Active control unit and ULP modules such as EIFE interface and IFM interface.
The BCIM module also provides isolation:
-
Between the MicroLogic Active control unit and other ULP modules.
-
Between the XF and MX communicating voltage releases.
The BCIM module is installed on the back of the MicroLogic Active control unit.
For information on installation, consult the instruction sheet on the Schneider Electric website: BRU4329407.
ULP Port Module
The ULP port module is an optional accessory that is mounted with the terminal blocks of the device.
The ULP port module:
-
Supplies the BCIM module.
-
Integrates the ULP termination.
-
Is required for connection to the EIFE Ethernet interface.
-
Allows the connection to external ULP modules, such as the FDM121 display or the IFE Ethernet interface.
For information on installation, consult the instruction sheet on the Schneider Electric website:
EIFE Embedded Ethernet Interface
This is an optional accessory which is mounted on the chassis of the drawout circuit breaker.
The EIFE embedded Ethernet interface enables drawout MasterPacT MTZ circuit breakers to be connected to an Ethernet network with the Modbus TCP/IP protocol.
It provides digital access to all the data delivered by the MicroLogic Active control unit. In addition, it monitors the position of the device in the chassis: connected, test, and disconnected.
For information on installation, consult the instruction sheet on the Schneider Electric website: NVE23550.
For information on usage, refer to DOCA0106•• Enerlin'X EIFE - Embedded Ethernet Interface for One MasterPacT MTZ Drawout Circuit Breaker - User Guide in Related Documents at the beginning of this guide.
IFE Ethernet Interface for One Circuit Breaker
The IFE Ethernet interface provides Ethernet access to a single circuit breaker with the Modbus TCP/IP protocol.
The circuit breaker is connected to the IFE interface through the ULP port module and a prefabricated ULP cord.
For information on installation, consult the instruction sheet on the Schneider Electric website: HRB49218.
For information on usage, refer to DOCA0142•• Enerlin'X IFE - Ethernet Interface for One Circuit Breaker - User Guide in Related Documents at the beginning of this guide..
IFE Ethernet Switchboard Server
The IFE Ethernet switchboard server provides Ethernet access to one or several circuit breakers with the Modbus TCP/IP protocol. It allows the following communication architectures:
-
One single circuit breaker connected to the IFE server through the ULP port module.
-
Up to 11 circuit breakers through IFM Modbus-SL interfaces stacked to the IFE server.
For information on installation, consult the instruction sheet on the Schneider Electric website: HRB49218.
For information on usage, refer to DOCA0084•• Enerlin'X IFE - Ethernet Switchboard Server - User Guide in Related Documents at the beginning of this guide.
IFM Modbus-SL Interface for One Circuit Breaker
The IFM Modbus-SL interface provides access to a single circuit breaker via a Modbus serial line communication network. The circuit breaker is connected to the IFM interface through the ULP port module or the COM terminal block and a prefabricated ULP cord.
For information on installation, consult the instruction sheet on the Schneider Electric website: NVE85393.
FDM121 Front Display Module for One Circuit Breaker
The FDM121 front display module for one circuit breaker shows the measurements, alarms, and operating assistance data from a single intelligent modular unit with a MasterPacT MTZ circuit breaker.
The FDM121 display with firmware version V004.000.025 or greater is compatible with MicroLogic Active control units. Earlier firmware versions need to be updated.
For information on installation, consult the instruction sheet on the Schneider Electric website: QGH80971.
