Customers want to use modbus communications in some applications.

Resolution:
* Electronic trip circuit breakers capable of modbus communication are all Powerpact H, J, and L breakers equipped with advanced (Ammeter or Energy style) Micrologic trip units,
* Powerpact P and R frame breakers with Ammeter, Power, or Harmonic style trip units, and
* Masterpact NT or NW breakers with Ammeter, Power, or Harmonic style trip units.


Modbus communication is optional and requires additional hardware on all PowerPact H, J and L frame breakers and PowerPact P and R frame breakers with an Ammeter trip unit.

Modbus communication is included as standard for PowerPact P and R frame breakers and Masterpact NT and NW breakers with Power or Harmonic style Micrologic trip units.
Modbus communication is included when specified for Powerpact P and R frame breakers and Masterpact NT and NW breakers with Ammeter trip units.

Powerpact H, J and L frame circuit breakers require a Modbus Interface Module (IFM) STRV00210 and an NSX cord.  See current Digest for appropriate catalog number for NSX cord based on system voltage and cord length.
For PowerPact H, J and L frame circuit breakers with Standard Micrologic trip units a BSCM with NSX cord is required to indicate breaker status. See current Digest for appropriate catalog numbers.
Other accessories are optional and may be required for specific functions.
