Check before you substitute
- Frame size versus the actual rating or trip setting
- Icu and Ics at the same voltage, poles and standard
- Trip unit: thermal-magnetic or electronic, and the settings you need
- Dimensions, mounting, terminals, handles and motor operators in the panel
- Your protection and selectivity study
