SIEMENSQ2020 Two 20-Amp Single Pole 120-Volt Circuit Breakers, for use only where Type QT breakers are allowed

Works great

great

Great product for a good price. Just what the doctor ordered.

I fit and works great

Used this to replace a faulty breaker.Make sure your main power switch is off and then install these at an angle until it clicks.No complaints and it seems made of a durable material and quality components.

works as it should so far

Siemans breakers are used in my breaker panel. And one of my breaker plates got broken. So i need to combine my larger qt desighn breakers to slim tandeum to make room. If you have the box i can only use qp version of the breaker on the lower half of the box. And qt versions any where in the box. And found this one. It is half the price they wanted in a lighting store. Lucky i did not need it right away. I have not installed it yet but see no problem with it.

The QT2020 breaker is a CTL (Circuit Total Limitation) style breaker and can only be installed in certain locations within the breaker panel - usually the lower 4 slots within the cabinet. The buss bar in those lower locations is notched to accept the CTL style breaker (and the standard breaker). These breakers have "lock-out" tabs that prevent them from being installed in other locations, and thus limit the total number of circuits that can be installed into a panel. What really adds to the confusion is that there is a "NON-CTL" version of this breaker (QT2020NC) without the "lock-out" feature and I have seen them at Lowes with the same bar code and stock number. HODO stocks the QT2020NC and charges $24+ for them versus $9+ for the CTL version.See the pictures to show the difference between the CTL and non-CTL version of this breaker.The bottom line is that even if the label on your breaker panel states that it accepts QT breakers, they may only fit into a few specific slots. If those slots have standard width breakers already in them, then you will have to shuffle the breakers around to allow these breakers to be placed into the CTL style slot. It is not an issue of a QP versus QT style panel, only a CTL or non-CTL slot location within that panel.
