What is an EH4, EHB4, EH7 and EHB7?

Issue:
What do the EH4, EHB4, EH7 and EHB7 designations for EH/EHB breakers mean?

Product Line:
Circuit Breakers

Environment:
E frame breakers

Resolution:
EH4/EHB4 is the designation given to 15-60 amp EH/EHB breakers, and EH7/EHB7 is the designation given to the 70-100 amp EH/EHB breakers.

The 70-100 amp breakers have the rejection feature to prevent breaker installation across from it in the panel.

However, the EH and EHB breakers are already obsolete.
