These “Qwik-Open” or QO breakers are the fastest opening breakers in use in the industry. They reportedly open after just one full power cycle of a 60 Hz AC line (about 1/60th of a second). These breakers feature a visual trip indicator and make it easy to quickly spot the tripped breaker in the panel.
What does QO stand for on Square D breakers?
QO® (plug-on) one-, two- and three-pole thermal-magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. Plug-on QO circuit breakers are for use in QO loadcenters, NQ and NQOD panelboards, OEM mounting bases, and Speed-D® switchboard distribution panels.
What breakers are compatible with Square D QO?
Square D QO breakers are compatible with QO breaker boxes and CSEDs. Each ANSI-certified and UL-listed. Homeline circuit breakers are built with the same Square D brand quality you have come to expect at a price that makes them the best value in their class.
What is the difference between Square D Homeline and QO breakers?
Homeline is the “price competitive” model from SquareD, QO is the higher quality panel. The difference is probably mostly due to historical reasons given all the consolidations in the electrical manufacturing industry.
Will QO breakers work in a homeline panel?
These circuit breakers are used for overload and short-circuit protection of your electrical system. Square D Homeline breakers are compatible with Homeline breaker boxes and CSEDs. Square D QO breakers are compatible with QO breaker boxes and CSEDs. Each ANSI-certified and UL-listed.
Are QO and QOB breakers interchangeable?
A QO breaker is plug on mounting, and can be used in QO load centers, old NQO and NQOD panelboards, and current NQ panelboards. A QOB breaker uses a bolt-on connection to the bus, and can be used in old NQOB and NQOD panelboards, and current NQ panelboards. Otherwise the breakers are the same.
What electrical breakers are interchangeable?
Specified breakers are breakers that have been tested and listed for a panel by the manufacturer. Interchangeable breakers are breakers that have been tested in the panels that they are approved for and are similar to specified breakers, typically by a third party such as Underwriter’s Laboratory (UL).
Can I use a Siemens breaker in a Square D panel?
The Siemens Type QD circuit breakers have been classified by UL for use in place of the Square D Type QO® listed circuit breakers in the Square D UL listed panelboards shown below.
Can you double tap a Square D breaker?
The only manufacturers that make circuit breakers that are designed to hold two conductors are Square D and Cutler-Hammer, but not all of their circuit breakers can be double-tapped.
Can I use Eaton breakers in a Square D panel?
Designed to fit virtually any panel

What circuit breakers are compatible with Siemens panel?
It’s Best to Choose Circuit Breakers Made by Siemens
I said the safest bets are QP, QT, QPF, and QAF breakers because they’re manufactured by the brand itself. Did you know that Murray and Siemens are pretty much the same company? Their breakers even use the same parts, but they are not certified to be interchangeable.
What breakers are compatible with Siemens?
The Siemens QP, QT, QAF, and QPF are the standard “interchangeable” plug-on type breakers used in loadcenters under several brand names including Siemens, Murray, Gould, and Sylvania to name the most common.
