Siemens Q3100 100-Amp Three-Pole QP Circuit Breaker – 240V Type QP

Reliable protection for home electrical systems

The Siemens Q3100 100-Amp Three Pole Type QP circuit breaker is built with thermal-magnetic technology that guards your wiring from overload and short-circuit events. It's designed for use in compatible Siemens enclosures and benefits from features that support quick, accurate wiring while helping keep your panel organized.

With a three-pole configuration delivering 100 amps at 240 volts, this breaker is suited for key feeder applications in many residential panels. It carries a 10,000 AIC interrupting rating, meaning it is designed to interrupt fault currents with high energy safely, reducing the risk of damage to connected circuits.

In everyday life, you may appreciate how this breaker supports routine maintenance by allowing you to isolate circuits safely, while the protective features add a layer of confidence when your home experiences voltage fluctuations or sporadic overloads. This model is a strong candidate when upgrading an older panel or configuring a new one, offering a balance of performance and practicality without promising specific results.

Notes on installation and warranty

For warranty considerations, Siemens recommends using Siemens breakers in Siemens panels. The use of non-Siemens or used breakers can void the panel warranty, so pairing the right components helps ensure compatibility and peace of mind.

Durability and build quality are hallmarks of the QP line. The unit is designed for long-term reliability in home electrical systems, with components arranged for safe heat dissipation and simple serviceability. When wired correctly, it provides consistent protection while remaining a manageable size for panel interiors. Choosing the right breaker size matters for system protection; the 100A rating matches typical main feeder configurations in many homes, while always aligning with your panel’s markings and the wire gauge of the circuits it serves. When in doubt, consult a licensed electrician for proper specification and installation.
