Product Overview

Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home’s 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.

  • 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

Does the code allow for using non circuit limiting (NCL) Type tandem breakers in panels that are not designed to increase the number of circuits, ie 20/20?
Asked by: Shaka
Hi Shaka, No, the NCL line of tandem circuit breakers are for use in panels manufactured pre-1968.

Helping a friend with his panel. It's a Siemens I-T-E load center G2020MB1100. Will the Q2020NC work in this panel?

Asked by: Ben
Hi Ben, Yes, a Q2020NC is designed to fit in a 20 space 20 circuit Siemens load center.

This product fits nicely in my panel except the blade depth is too shallow, is this simply the wrong product?

Asked by: jason
Hi jason, It sounds like you may have a Q2020U circuit breaker as opposed to the Q2020NC. The Q2020NC is designed for use in panels that do not typically accept tandem circuit breakers (I.E. a 20 space 20 circuit panel).

Is it possible for one switch to work and the other not work?

Asked by: Lowsey
Hi Lowsey, It would depend on the install, because these tandem circuit breakers are not common trip circuit breakers and are not tied by a handle tie it could be possible to see one of the poles trip while the other does not.
