Product FAQs
5 answersWhich panelboards are compatible with the QOB230EPD1200?
This bolt-on circuit breaker is designed exclusively for Square D NQ and NQOD panelboards. It cannot be installed in standard QO load centers, which require plug-on breakers.
What does the EPD designation mean on this breaker?
EPD stands for Equipment Protection Device. It provides 30mA Class B ground fault protection, which is designed to protect sensitive machinery and equipment from low-level ground faults, rather than providing the 5mA Class A protection required for personnel safety.
What does the 1200 suffix indicate on the QOB230EPD1200?
The 1200 suffix indicates that this breaker includes a factory-installed 1A auxiliary switch. This switch provides remote indication of the breaker's status for monitoring and control systems.
How is the neutral connection handled on this breaker?
This breaker features a pigtail neutral connection. The attached white pigtail wire must be connected directly to the panelboard's neutral bus bar to ensure the ground fault protection functions correctly.
Does this breaker include a Visi-Trip indicator?
Yes, it features the Square D Visi-Trip indicator. When the breaker trips due to an overload, short circuit, or ground fault, a highly visible red indicator appears to help you quickly identify the tripped breaker in the panel.

Great price. Fast delivery. My local electric distributor wanted double for the same breaker, so it was a no brainer to order this one. Ordered another one since with the same great service.
