Ingersoll Rand / WEG Replacement Reference

Replaces Ingersoll Rand 24141111 as the current WEG CWB-series contactor/starter solution for applications originally using the WEG CWM40-00-20V24 contactor. Ingersoll Rand factory starter documentation identifies IR 24141111 as the legacy WEG CWM40-00-20V24 contactor in a 230V, 7.5 HP single-phase WEG enclosed starter assembly. WEG's current CWB38 family supersedes the discontinued CWM40 contactor class.
