What breaker brands are compatible with Siemens?
General Switch, Westinghouse, Murray, Challenger, Arrow Hart, and General Electric serve as good examples of such brands. However, that doesn't always mean that the breakers they produce are also compatible with Siemens panelboards.09-Feb-2022
Are Siemens and Square D breakers compatible?
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.
What is the difference between Siemens QP and QT breakers?
The QP breakers are standard 1" per pole branch breakers. The QT breakers are duplex "space saver" breakers that combine 2 independent 1/2" breaker poles in a common unit.
Will a GE breaker fit in a Siemens panel?
Siemens breakers can be used in GE breaker boxes, and they are generally known to be compatible. Match the size and voltage requirements when using Siemens breakers, as using the wrong breakers can have dangerous results. If the wrong breaker is used it could fail to break (shut off power) during a surge.
What circuit 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).10-Jun-2021
Who makes Siemens breakers?
The simple answer is, of course, Siemens – they make their own well-known and durable breakers. Siemens has been around for over 150 years in engineering and world history in general.01-Jun-2019
Is Square D better than Siemens?
Reasons To Choose a Square D Electrical Panel There are many electricians as well as homeowners who believe that the choice between a Square D electrical panel and a Siemens electrical panel really boils down to personal preference because they are both equally high quality.19-Jul-2021
What breakers fit in a Square D panel?
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.
Can you mix breaker brands?
Brand: Always install the correct brand of breakers in your breaker panel. While some breakers are interchangeable, many are not, even if they look the same. Replacing one brand of breaker with another can be dangerous, may void your breaker or panel warranty, and may lead to a failed electrical inspection.

Product Description
Siemens Classified circuit breaker Type QD replacement for Square D type QO. It has a 1 Pole 20 Amp construction.
How to replace a breaker in a panel?
The straightforward answer is: read your panel for manufacturer’s instructions on acceptable breaker replacements. If the instructions are hard to read (normally they fade over time), then check your existing breakers and replace those with the same type. Firstly, remove one of the old breakers to make sure the panel connections are the same. Lastly, test the fit of the new breaker in the panel before you put it in place.
Can you replace UL circuit breakers?
Alternatively, you can replace them with UL Classified circuit breakers specifically for your panel. Below is an example of a compatibility chart by Eaton. This is a cross reference of Type CL 1” breakers that could be interchangeable for panel installations. Check under the Siemens column for compatible Eaton UL Classified breakers.
What is an arc fault circuit interrupter?
Combination Type Arc Fault Circuit Interrupters (AFCI) detect arcing faults (an unintentional arcing condition in a circuit) that standard circuit breakers are unable to detect. The device is intended to mitigate the effects of arcing faults by functioning to de-energize the circuit when an arc-fault is detected. You may ask yourself "where do I need arc fault breakers?" You need them at home! A Combination Type AFCI detects all three types of arcing: line-to-neutral, line-to-ground, and series arcing.
How to close a modal window?
This is a modal window. This modal can be closed by pressing the Escape key or activating the close button.
What is CAFCI technology?
This new technology created by Siemens expands the capabilities of the CAFCI by feeding two separate circuits from one breaker position – saving both space in the load center and installation time, all while maintaining safety and compliance. This is ideal for new construction or renovations and is available in either Plug-On Neutral or Pigtail versions.
What is a shared neutral?
Reduces wiring costs and installation time by enabling contractors to use multi-wire branch circuits, commonly known as "shared neutrals". When using single pole CAFCIs, a dedicated neutral is required for each circuit. It allows electricians to share neutrals between the two circuits fed by the breaker.
What is a Siemens main breaker?
Siemens main breakers (MBK) are designed to allow for convertibility and invertiblilty of Siemens load centers.
When will one LED be illuminated?
One LED will be illuminated if the last trip was a result of an arcing fault.
Do CAFCI breaker lines have a neutral lug?
CAFCI breakers now have a single load lug (s) only. Wiring made easier with the neutral lug removed. These breakers can be installed in the same manner as the thermal magnetic breakers. This allows the installer to land ground and neutral conductors in the load center before installing the breaker and load conductor. The new design allows for the same reliable installation method using the neutral clip as the line side clip. The small footprint allows for over 4 inches of wire bending space.
What breakers are compatible with Siemens?
Your safest bets are Siemens QAF, QPF, QT, and QP. The most recommended way to know what breakers are compatible with Siemens, check your panelboard’s manufacturer’s manual.
Can I cut a breaker with a saw?
Check whether it fits the slot intended for it. Believe it or not, some subcontractors even cut breakers with a saw just to make them fit. While that might work, you’ll essentially be playing with fire, literally and figuratively, if you decide to do so.
Who makes UL breakers?
UL classified breakers, especially those made by Eaton, are an exception to what I said. Why? They’re designed for interchangeability with Siemens breakers, simply put.
What is an Eaton UL circuit breaker?

What is UL classified?
UL classified circuit breakers are produced by one manufacturer for use in place of the breakers specified on the panelboard. Like specified breakers, UL classified breakers have been tested in the panels for which they are approved.
