Product FAQs
5 answersWhich panelboards accept the EH34030 circuit breaker?
The EH34030 is engineered specifically for plug-on installation in legacy Square D NEHB panelboards. It cannot be installed in modern NF series panels or standard QO and Homeline load centers.
Is there a bolt-on alternative to this breaker?
Yes. The EH34030 features a plug-on mounting design. If your NEHB panel setup requires a mechanical bolt-on connection, you will need to cross-reference to the EHB34030.
Can I substitute a newer EDB series breaker for the EH34030?
No. Although the EDB series is the modern successor to the EH and EHB lines, EDB breakers are built exclusively for NF panelboards and are physically incompatible with older NEHB enclosures.
Does this breaker feature a visual trip indicator?
Yes, EH series circuit breakers feature Square D's Visi-Trip indicator. This displays a highly visible red flag when the breaker trips, helping maintenance personnel quickly locate faults in the panel.
Is the EH34030 approved for HVAC equipment?
Yes, this breaker carries an HACR rating, making it suitable and approved for use with heating, air conditioning, and refrigeration systems that require this classification.
