What is the replacement for a CCM cradle communication module S48377 for Masterpact breakers?
Issue:
In an existing installation with a 4w Modbus network, a CCM S48377needs to be replaced. Since the CCM is obsolete, what replaces it?
Can the CCM be replaced with only an IO Module? Are other parts needed?
Product Line:
Circuit Breakers
Environment:
Masterpact drawout breakers
Resolution:
The CCM is replaced by an IO module LV434063. Other hardware is required to interface with the breaker and with the modbus network.
For quick reference, here are the steps. Refer to the drawing and the parts list on the attachment.
