Introducing Siemens Low Voltage Residential Circuit Breakers – the guardians of your home's electrical safety. These circuit breakers, known as Type QP/MP, are like the watchful keepers of your power, ensuring a smooth and secure energy flow.
Think of them as traffic managers for your home's electrical highways. With 3 poles and the ability to handle 240VAC, they're equipped to handle the electricity that powers your home. But here's the interesting part: they use Thermal Magnetic technology to detect when there's an excess of electricity (more than 90 amps) or a short circuit. When they detect a problem, they act swiftly to halt the electricity flow, preventing potential dangers.
But their talents don't stop there. These circuit breakers are versatile multitaskers. They serve as protective guards for your circuit protection load center – the point where electricity enters your home. They also act as feeders, directing electricity to the right destinations. Plus, they're adept at managing miniature circuits, ensuring even the smallest parts of your home stay safe.
Safety is their core strength. These circuit breakers meet the UL 489 standard, a testament to their adherence to the highest electrical safety standards. With them in place, you can trust that your home is well-protected.
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 sentinels that stand between your home and potential electrical risks. Thanks to Siemens, your home remains secure and powered, no matter what electrical challenges arise.
