Introducing Siemens Low Voltage Residential Circuit Breakers – the guardians of your home's electrical safety. These Miniature Thermal Magnetic Circuit Breakers, specifically Type QP/MP with 3 poles and a voltage rating of 240VAC, are like vigilant protectors for your electrical systems.
Imagine them as traffic controllers for your home's electricity. Designed for Electrical Distribution applications, they play three vital roles: first, they safeguard Circuit Protection Load Center Mains, ensuring the incoming power is secure. Second, they act as Feeders, directing electricity to various parts of your home. Third, they excel as Miniature Circuit Breakers, offering protection even to the smallest circuits.
Here's their secret power: they utilize Thermal Magnetic technology. This means that if there's ever too much electricity (above 20 amps) or a short circuit, they detect the issue and promptly intervene, preventing potential hazards.
Safety is paramount – these circuit breakers meet the UL 489 standard, a mark of approval from experts in electrical safety. With a 3-pole design and an interrupt rating of 10 AIC, they act as your home's electrical defenders, always prepared to keep your surroundings safe and secure.
Think of these circuit breakers as the security detail for your home's electrical system. With their versatile roles, 3 poles, and strong interrupt rating, they're like the ultimate protectors against potential electrical issues. Thanks to Siemens, your home remains powered and protected, no matter what electrical challenges come your way.
