  • Easy plug in connections in Siemens load centers and meter combos
  • Accepts #14-6 AWG Cu or #14-6 AWG Al wire
Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your homes electrical system. To provide additional protection Siemens offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and Voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current.
  • Tandem 20 Amp 120-Volt type QT non-current limiting circuit breaker
  • 10,000 AIC interrupting rating
  • Siemens type QT circuit breakers provide easy plug-in connections in Siemens enclosures and the time saving insta-wire feature
  • Compatible with Siemens PL and ES series load centers
  • Use for overload and short-circuit protection of your electrical system
  • Thermal-magnetic

Questions & Answers

In your previous answers, you said this tandem breaker can be used in a G2020MB1100 breaker panel. I thought the G2020MB1100 can only support 20 circuits, does using a tandem overload the box? I current have 3 tandem breakers in this box and my home inspector noted that it doesn't meet code. thanks
Asked by: Mike
The manufacturer lists on the label on the door of the panel if a tandem breaker can be used in that panel and which slots you can use them in. Any tandems installed in a slot which is not designated for a tandem, is a violation.

I can use this in a QE panel

Asked by: Franklin
If the panel in question is from another manufacturer we cannot advise. Please contact the manufacturer for guidance on approved breakers for your panel. If it is a Siemens of Siemens legacy panel (ITE, Murray, Crouse-Hinds, etc.) we will need more information.

Without knowing the panel catalog# to confirm please check the label on the inside of the door if there is a QT breaker designation listed under the breaker family types you can use that breaker.

Can I use this in a Crouse-Hinds E26095 panel? There are already a couple of tandem breakers in it and appears it will accept more in other spaces.
Asked by: Rintho
Q2020NC should only be used in Non-CTL panels (manufactured prior to 1968). Also, for Crouse-Hinds load centers Murray labeled breakers should be used. If tandem breakers are approved (we can only verify with the load center catalog number from inside door label) please consider MP2020U. Note E26095 is the UL file number not the catalog number.
