A circuit breaker is an electrical device that protects electrical circuits from damage due to an overload or short circuit. The 3120-F311-P7T1-W15GY3-3A circuit breaker is designed to protect residential and commercial applications with a working current up to 250 amps. It is a multi-pole breaker that can be used to protect single-phase, two-phase, or three-phase electrical systems.

The 3120-F311-P7T1-W15GY3-3A circuit breaker is made up of a molded case, busbar, contact assembly, trip unit, and a manual trip button. It operates using a thermal-magnetic system, which prevents electrical overloads from drawing too much current and causing a fire or damaging the electrical system. A "thermal trip" monitors the amount of current flowing through the breaker. When the current overload reaches a certain level, the thermal trip will activate and cut off the power. At this point, the breaker must be manually reset.

In addition to the thermal trip, the 3120-F311-P7T1-W15GY3-3A circuit breaker also includes a "magnetic trip" feature. This feature monitors the current flowing through the breaker and will automatically trip if it detects an abnormal current flow. This helps provide additional protection against short circuits and provide a higher level of protection for sensitive electrical systems.

The 3120-F311-P7T1-W15GY3-3A circuit breaker is designed for residential or commercial applications and is UL 489-listed. It is designed to be installed in an electrical panel and is perfect for use in homes, offices, schools, medical facilities, and other commercial environments. It has a high interrupting rating that meets or exceeds UL, CSA, and IEC standards, making it a reliable choice for protecting sensitive electrical circuits.

The 3120-F311-P7T1-W15GY3-3A circuit breaker is an effective and reliable way to protect against potentially hazardous electrical overloads. With its multi-pole structure, it is perfect for residential, commercial, and industrial applications. Its thermal-magnetic trip system is designed to protect against the most common causes of electrical overload. And with its UL Listing, it offers maximum safety and protection against potential circuit damage.
