Product FAQs
4 answersWhich panelboards accept the Square D EH34015 circuit breaker?
The EH34015 is engineered specifically for legacy Square D NEHB panelboards. It utilizes a plug-on mounting configuration that matches the bus structure of these older commercial panels.
What is the difference between the EH34015 and the EHB34015?
Both breakers share the same 15A, 3-pole electrical specifications and fit NEHB panelboards. The difference is the mounting style. The EH34015 is a plug-on breaker, while the EHB34015 is the bolt-on equivalent.
Can I replace the EH34015 with a modern EDB series breaker?
No. Modern EDB, EGB, and EJB circuit breakers are designed for current Square D NF panelboards and will not physically fit into legacy NEHB panelboards. You must use an EH or EHB series breaker to maintain compatibility with an existing NEHB panel.
How does the EH34015 indicate a tripped condition?
This breaker includes the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, a highly visible red indicator appears, allowing electricians to quickly identify the faulted circuit in a crowded panelboard.
