Product Overview

  • Provides a manual means of energizing and de-energizing a circuit
  • 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 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.
  • Single pole, 20 Amp 120-Volt type QP interchangeable circuit breaker
  • 10,000 AIC interrupting rating
  • Siemens type QP 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

Are the lugs rated for only 1 wire?

Are the lugs rated for only 1 wire?

The description indicates this item is only compatible with 14ga wire. If this was a 15A breaker ...

The description indicates this item is only compatible with 14ga wire. If this was a 15A breaker that would make sense. However, if you are worried about sizing a circuit to the extent that you are using a 20A breaker, you should also be using 12 ga wire, which this device does not appear to allow. What item do you offer that will allow the use of 12ga wire?
Asked by: Finallydidit
March 20, 2017 Hello, This is the correct breaker to use with a typical residential installation of 12 AWG wire. ( We will fix the description). In any case, please consult with a licensed electrician when inquiring about wiring issues. Thanks, To Siemens Product Expert: This has not yet been "fixed."

Im installing new wiring, with the breaker open I️ am checking to see that the hot wire is not compromised by doing a sound continuity test, it rings

Im installing new wiring, with the breaker open. I️ am checking to see that the hot wire is not compromised by doing a sound continuity test to ground, it rings up. Is this the design of this breaker?
Asked by: Newbie
Make sure you have no devices on that circuit plugged in. If you don’t then you have a short/ground.
