## Description

Siemens bietet eine breite Palette von thermisch-magnetischen Leistungsschaltern, die das Schlüsselelement für den Überlast- und Kurzschlussschutz des elektrischen Systems Ihres Hauses sind. Um zusätzlichen Schutz zu bieten, bietet Siemens Leistungsschalter zum Schutz vor schweren Stromschlägen oder Stromschlägen, zur Minderung des Risikos von elektrischen Bränden und zum Schutz vor schädlichen Überspannungen und Spannungsspitzen an. Leistungsschalter sind zum Schalten und Schutz der Verkabelung Ihres Hauses vor hohen Temperaturen bestimmt, die durch Überstrom verursacht werden, der hher ist als die Nennleistung des Drahtes. Während thermisch-magnetische Leistungsschalter das Schlüsselelement für den Überlast- und Kurzschlussschutz Ihres elektrischen Systems sind, gibt es potenziell gefährliche Bedingungen, die keinen Überstrom beinhalten. Um sicherzustellen, dass die Garantie auf einem Siemens-Panel nicht erlischt, ist die Verwendung von Siemens-Unterbrechern erforderlich. Siemens empfiehlt dringend vom Einsatz von "gebrauchten" Brechern. Durch den Einbau gebrauchter Unterbrecher in einem Siemens-Panel wird die Garantie auf das Panel erlischt. Siemens verkauft keine gebrauchten Brecher und hat keine Drittanbieter dazu zugelassen.

## Questions & Answers

**Q: Will this work in a GE box?**
A: will not be up to code, even if it fits who knows how durable the connection would be, just buy the correct product https://www.amazon.com/dp/B000IK4LNO

**Q: Will this breaker work in a Homeline panel?**
A: Nothing will fit into a HomeLine panel execpt Homeline breakers. Thanks,Charles

**Q: will this breaker work in cutler hammer box**
A: Why don’t you just buy a cutler hammer breaker?  Even if it will fit, it is not rated for it or made to work with it. All that is going to do is lead to problems

**Q: Will this work in a Murray pannel?**
A: 04/04/19

Hello & thank you for this inquiry!!  Yes, this Q2125 should fit inside a Murray panel. The Murray Type MP circuit breakers and the ITE/Siemens Type QP circuit breakers are identical to one another and are interchangeable amongst their panels. Obviously, you should consult a professional electrical contractor before adding any breakers to a panel and just make sure that this is a valid item required.  

Thank you & if you have any additional questions, please feel free to contact us!  Thanks!
