Introducing Siemens Low Voltage Residential Circuit Breakers – the guardians of your home's electrical safety. Think of them as your trusty security team, keeping watch over your electricity and ensuring everything runs smoothly.
These circuit breakers, specifically the Type QP/MP with 3 poles, are equipped to handle 240VAC – the power that runs through your home. They might look small, but they have a powerful ability: they use Thermal Magnetic technology to sense when there's too much electricity flowing (more than 40 amps) or if there's a short circuit. When they detect trouble, they quickly step in to stop the flow of electricity, preventing any potential hazards.
These versatile heroes have a triple role. They protect the circuit protection load center, which is like the gateway for electricity entering your home. They also act as feeders, making sure electricity is distributed correctly. And don't forget their knack for handling miniature circuits – those smaller parts of your home's electrical system.
Safety is their top priority. These circuit breakers meet the UL 489 standard, a stamp of approval from experts in electrical safety. You can have peace of mind knowing your home is in good hands.
Imagine these circuit breakers as your home's electrical defenders. With 3 poles and an interrupt rating of 10 AIC, they're like the vigilant guards that prevent any electrical issues from escalating. Your home stays secure, thanks to these reliable Siemens circuit breakers.

I placed an order with Sonic Electric and after receiving needed to return the items. I was so pleased to get prompt personalized attention and a full refund. So nice to do business with a customer oriented company.

I recently ordered two pop-up outlets for a kitchen island. One of them won't stay closed. I emailed customer service, and after a couple of email exchanges and a photo, they are shipping a replacement. Things like this can be an absolute hassle, but they were great. I would not hesitate to order from them again.
