Description
Part of the classic EH series, the Square D EH24015 provides reliable thermal-magnetic protection for commercial systems. This 15-amp, two-pole breaker safeguards branch circuits against overloads. It features a plug-on mounting style specifically engineered to fit legacy Square D NEHB panelboards. If a mechanical connection is required, the bolt-on EHB24015 serves as a substitute. Rated 14 kAIC at 480Y/277VAC, the unit includes a Visi-Trip indicator for quick fault identification.Specifications

Product FAQs
6 answersCan I install the EH24015 in a modern Square D NF panelboard?
No. The EH24015 is designed exclusively for legacy NEHB panelboards. Modern NF panelboards require EDB, EGB, or EJB series circuit breakers.
What is the bolt-on equivalent to the EH24015?
If your NEHB panelboard requires a mechanical bolted connection instead of a plug-on connection, the EHB24015 serves as the direct bolt-on substitute.
What does the 480Y/277VAC rating mean for system compatibility?
The slash voltage rating indicates this breaker is only suitable for solidly grounded wye systems where the line-to-ground voltage does not exceed 277V. It cannot be used on 480V ungrounded or corner-grounded delta systems.
Is the EH24015 still actively manufactured by Square D?
No, the EH frame and the corresponding NEHB panelboards are legacy products that have been discontinued. However, replacement breakers remain available to service existing installations.
Does the EH24015 require mounting hardware?
No, the EH24015 features a plug-on mounting design that snaps directly onto the NEHB panelboard bus. If your specific panel configuration requires bolted connections, you will need the EHB24015 instead.
Does the EH24015 provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic breaker designed for overload and short-circuit protection. It does not feature integrated GFCI or AFCI circuitry.
