History and Replacement Context
The EHD series was developed for 480V industrial applications where the standard 600V-rated F-Frame was not required. The E-Frame 480V rating allows for a more compact design optimized for 480V systems.
Typical Applications
- 480V industrial distribution
- Motor branch circuit protection
- Commercial 480V panels
- Industrial branch circuits
