Product FAQs

5 answers
What panelboards are compatible with the Square D EH24050 circuit breaker?

The EH24050 is a plug-on circuit breaker designed exclusively for legacy Square D NEHB panelboards. It will not fit modern NF or NQ series panels.

Is there a bolt-on alternative to the EH24050?

Yes, the EHB24050 is the bolt-on equivalent to this breaker. Square D NEHB panelboards are designed to accept both plug-on (EH) and bolt-on (EHB) circuit breakers.

Can the EH24050 be installed on a 480V ungrounded delta system?

No. The 480Y/277VAC slash rating indicates this breaker is only suitable for solidly grounded wye systems where the line-to-neutral voltage does not exceed 277V. It is not rated for straight 480V delta systems.

How does the EH24050 mount into the panelboard?

The EH24050 features a plug-on connection that engages directly with the bus bars of an NEHB panelboard. Unlike the EHB series, it does not require bolt-on mounting hardware.

Does the EH24050 include a visual trip indicator?

Yes, Square D EH series breakers feature a Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, a highly visible red indicator appears to help quickly identify the faulted circuit.
