Will the Compact NSX breaker be for sale in the USA or Canada?

Where can I buy a Compact NSX breaker?

Product Line:
Circuit Breakers

There are no plans for a general release of the Compact NSX breaker line in North America, since the NSX is not UL Listed to UL489 (UL 489 is the standard commonly required in the US). In the US, the PowerPacT circuit breakers should be used (PowerPacT breakers are UL, CSA, and IEC rated).

For support on these breakers, Please see the following link to Global Operations where you can select other countries:

How to configure a C-Bus Automation Controller to SE8350 or SE8650 Room Controller for Modbus RS-485 communications

Upon successful login to the C-Bus 5500NAC2 (Network Automation Controller) or 5500AC2 (Application Controller)

Setting Modbus RTU Settings
1) Select the Configurator option from the 5500NAC2 / 5500AC2 - start page 
2) Select the Modbus tab to display modbus devices, settings and options
3) Select the RTU Settings option in the bottom left corner
4) Check the RTU (serial) enabled option for an available RTU connection 
5) Set the port to /dev/RS485 
6) Set the baud rate to match baud rate set in SE8350 or SE8650 (possible options - 4800, 9600, 19200, 38400, 57600)
7) Set the parity bit to match parity set in SE8350 or SE8650 (possible options none (1 stop bit), odd, even, none (2 stop bit). 
8) Set duplex option to "half duplex"
9) Select the Save button to set the Modbus RTU Settings

RTU Settings Dialog

Scanning Modbus RTU for Devices
1) Select the RTU Scan option in the bottom left corner
2) Enter the Scan range start (COM address of first SE8350/8650 in daisy chain) 
3) Enter the Scan range end (COM address of last SE8360/8650 in daisy chain) 
4) Select the Save button to start RTU scan for modbus devices

RTU Scan Dialog

5) From the RTU Scan results - check the add device option and specify the name, modbus profile (SE8300, SE8600 or SER8300 depending on series of SE Room Controller). 
Note: The SE8300 series profile covers the SE8350 room controllers, SE8600 series profile covers the SE8650 room controllers. 

RTU Scan Result Dialog

6) Select the Save button to add the devices to the list of modbus devices

Adding User Parameter Objects - Needed for Modbus Mapping
1) Select the Objects tab from the configuration page tabs to display C-Bus Automation Controller objects
2) Select the Add New Object option in the bottom left corner to add a user parameter which will later be mapped to a modbus device register
3) Select User Parameter option from the Application dropdown
4) Add a new variable address and provide a meaningful tag name
5) Select an option that matches the modbus register type from the Data type dropdown (eg floating point for temperature reading or temperature setpoint)
6) Specify keywords, units, comments as appropriate
7) Select the Save button to add the new user parameter to the list of C-Bus Automation Controller objects

Add Object Dialog

example: the newly added user parameter object will appear in the objects list and its value prior to modbus mapping will be shown as the default value in this case 0.000°C

User Parameter Object

Mapping Modbus Device Registry to User Parameter
1) Select the Modbus tab from the configuration page tabs
2) From the modbus device list select the applicable modbus device's mapping icon under the mapping column
3) From the modbus device's register list select the link to object field next to the modbus register to be mapped
4) From the mapping dialog use the link to object dropdown list to link the modbus register to the corresponding user parameter
5) Specify the value delta, units, keywords and comments as applicable
6) Select Save button to link the modbus device register to the user parameter object

Modbus Mapping Dialog

Check User Parameter value for updates from SE8350/8650 Room Controller
1) Select the Objects tab from the configuration page tabs to display C-Bus Automation Controller objects
2) Check that the User Parameter object which was just mapped from SE8350/8650 modbus device register is updating as expected

example: we can see the Room Temp user parameter is being updated from the Room Controller One - Room Temperature modbus registry

Mapped User Parameter Object

What does the "383" suffix represent on and ATV71....N4383 ?

 "383" suffix on and ATV71....N4383

Product Line:

ATV 71H075N4…HD75N4


Variable speed drive for synchronous motor with speed feedback
The drives are supplied as standard for asynchronous motors with or without sensor feedback.
ATV 71H075N4…HD75N4 drives can control not only those motors included in the standard offer, but also synchronous motors with speed feedback, by adding 383 at the end of the reference.
Example: ATV 71H075N4 becomes ATV 71H075N4383.
See available encoder interface cards.

Which direction the H1 side of MTZ neutral CT (TCE external sensor) to be installed?

Please see below diagram from the MTZ Neutral Current Transformer Instruction Sheet.


As you can see, H1 is always oriented to the bottom side (of the breaker) and H2 to the top side (of the breaker)
In fact, the CT is always installed in the same way whatever the way the breaker is fed (top or bottom)

Please see the below illustrations for better understanding. 

You can install the neutral CT above or below or same level as the breaker, but H1 side of the neutral CT is always facing the direction where the bottom of the breaker is. Please see below.

The reason for this is that the internal CTs installed inside the beakers, face their H1 side towards the bottom terminals of the breaker. Since, we cannot change the orientation of the internal phase CTs, we have to match the same orientation in the neutral CT as well. i.e. H1 is always oriented to the bottom side (of the breaker) and H2 to the top side (of the breaker)

Why choose Type B RCD for 3 Phase Variable Speed Drives?

For the 3 Phase Variable Speed Drives, the RCD type B or type B-Si is particularly suitable.
It protects against fault currents with DC offset, which is true for three-phase power converters. In addition, it has enhanced immunity against nuisance tripping caused by:

  • EMC common mode filters connected upstream VSD.
    Type B has a tripping delay allowing the inrush current to flow on power up.

  • The permanent switching leakage currents existing in power converters (ex: 25kHz).
    Type B include a "low pass" filter to ensure a trigger threshold which increases with frequency while complying with the personal protection curve (fibrillation).

Please note: if the required sensitivity is 300mA, Selective type RCD should be proposed ensuring a non-triggering time of 50ms. 

More information can be found on the Earth Fault Protection guide: https://download.schneider-electric.com/files?p_enDocType=Catalog&p_File_Name=CA908066E+%28web%29.pdf&p_Doc_Ref=CA908066E

With regards to installation of these RCDs, they are mounted upstream of the Variable Speed Drives.
