Installation Notes
• These listed part numbers are direct replacements.
• New Eaton mounting hardware is required.
• Verify the replacement matches your application before installation.
• Contact Essential Parts if you need assistance identifying the correct replacement.
Are These Direct Replacements?
Yes—for the part numbers listed above.
According to Eaton’s official replacement documentation:
- Same electrical application
- Same current rating
- Same number of poles
- Same circuit protection function
- Direct replacement using Eaton’s updated mounting hardware
Because the Power Defense platform uses a different physical mounting arrangement than legacy Series C breakers, new mounting hardware is required during installation.
Why Upgrade to Power Defense?
While many Series C breakers continue to provide reliable service, Power Defense offers several advantages for new installations and replacement projects:
- Modern breaker platform backed by Eaton
- Expanded interrupting capacity options
- Improved accessory system
- Available electronic trip units
- Integrated communications on select models
- Simplified future maintenance
- Long-term product availability and support
