Product Description

Product Description

Siemens space saving, plug in circuit breakers are intended for use in Siemens EQ, Siemens Ultimate, ITE, and Gould load centers and meter combinations that are rated to accept type QT breakers. Check wiring diagram to confirm. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required. The quadplex breakers provide two double pole breakers in half the space of standard sized breakers. These triplex, 1/2-Inch frame breakers are ideal when new circuits are required in a panel that has no available spaces. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so.

4.0 out of 5 stars Siemens but be carful what panel you have
Reviewed in Canada on September 12, 2021
I have been an electrician in BC Canada for 30 years. These are Siemens breakers, however I am assuming in the USA they have some different rules regarding breakers combinations that can be installed in panels. These Quads and Tandems, are coming with rejection clips. This is indicated in the part or model number wit a CT on the end of the number. indicates CTL (circuit total limitation). They will not fit the majority of Siemens panels installed in Canada, there are different models of panels that the tabs the breakers are installed on have notches in the middle allowing the rejection clip to slide down into. These clips are not removable and may crack the breaker if attempted. You can see in some of he Siemens panels some have these notches in the buss. 100% of the ones I have installed form Canadian Wholesalers do not have these. The pictures show the ones from Amazon and the ones from Canadian Wholesalers and most Hardware Stores I suspect.

The Web site says that this item is for use in Siemens panels that accept type QT circuit breakers. While my panel accept type QT breakers, as clearly stated in the picture attached taken from my panel, this item does not fit. As I am finding out now having done more research to understand why, as reported by other reviewer, this item will not fit the majority of Siemens panels installed in Canada, even those that accept QT breakers like mine. The issue is that the notches at the back of this item if half the size, and thus will not fit completely in the panel – simply put, it is impossible to enter fully in the panel. I have attached a picture to show the difference, and it is significant – the bottom breaker is the one sold on Amazon, while the breaker in the top is the one I wanted to replace in my panel. It is really puzzling why a breaker made by Siemens will not fit in a Siemen Panel that can accommodate QT breaker. This advertised QT Siemens breaker on Amazon cannot be a QT model as it does not fit at all in a Siemens Panel that can fit QT model. As of 29 Sept 2021, I found additional information - The "CT" breaker will only fit in panels that have a bus bar with two narrow contact legs; not in panels that have a single wide contact for opposing (left/right side) breakers. Those with the single wide contact need the "CTNC" type.

The CT is for Circuit Total limitation, also called a rejection tab. Measure top of breaker slot, mine is 18 mm, these are 10 mm. That is why they won’t push in correctly. They are QT breakers but the CT in the part number makes them incompatible. When I buy the same breakers at Home Depot canada they fit. These don’t.
