Do Powerpact and Masterpact circuit breakers ordered with modbus communications communicate breaker status (ON, OFF, TRIPPED)?

Do breakers with modbus communicate the breaker position?

Product Line:
Powerpact H J L M P R 
Masterpact NW/NT

Applies to trip units with BSCM or BCM

P and R and Masterpact breakers ordered with modbus come standard with switches that allow modbus to communicate breaker status.  The breaker status switches also come with the BCM modbus kit for field installation.

With H/J/L breakers, the IFM module LV434000 is din rail mounted external to the breaker and you need to order the breaker with a BSCM (Breaker Status and Control Module) S434201BS or S434202BS accessory.  These accessories include the required NSX cord for connecting to the modbus module, S434201BS has a 1.3 m cord and S434202BS has a 3 m cord.
