Circuit breakers are devices used to protect electric circuits from damage due to overloads and short circuits. These protective devices are commonly used in homes and businesses alike to prevent circuit breakers from tripping or to shut off power in case of an emergency.

The 3120-F521-P7T1-W19DG4-16A circuit breaker is a device that interrupts or breaks the continuity of an electrical circuit when a certain amount of current is exceeded, which could result from an overload or short circuit. It is designed to disconnect the circuit only when needed to protect the wiring from too much current and the electrical equipment from voltage spikes. The 3120-F521-P7T1-W19DG4-16A is available in various sizes and ratings for use in multiple applications such as residential and commercial establishments.

The 3120-F521-P7T1-W19DG4-16A is designed to provide circuit protection and is ideally suited for general-purpose use in residential service panels. It is a circuit breaker which is installed in a circuit breaker panel and used to automatically open the circuit when it senses an overload or short circuit. It is suitable for use with standard single phase and three phase circuits, as well as larger multiple circuit installations. The 3120-F521-P7T1-W19DG4-16A also uses a master trip system to allow one breaker to trip all the other breakers in the panel. This is ideal for buildings with multiple load centers, such as hotels or office buildings.

The 3120-F521-P7T1-W19DG4-16A breaker is operated by a thermal-magnetic trip unit. This device contains a bimetal element which when heated by a current, will move and open the contacts, thereby breaking the circuit. The unit also has a magnet that works in conjugation with a solenoid. The solenoid is energized when a short circuit occurs causing the armature to be drawn downward, pulling an internal trip shaft, thus opening the contacts. It is important to remember that the trip unit must be capable of disconnecting the circuit at the maximum prospective short circuit current of the system in order to provide proper protection.

The 3120-F521-P7T1-W19DG4-16A is made up of a molded case to protect its components and has a number of features that make it an ideal choice for protecting circuits from damage. It is constructed of a high impact resistant thermoplastic material and can withstand abuse from dust, dirt, and humid environments. The device is also coated with a corrosion-resistant enamel to further protect it from corrosion and wear. Additionally, this circuit breaker is equipped with a Venturi system to ensure that no arcs are visible while the breaker is operating in its normal mode.

The 3120-F521-P7T1-W19DG4-16A is designed to withstand high in-rush currents associated with most inductive loads, including motors, transformers, and lighting. It also features a protection curve that is specifically designed to handle the high amounts of current associated with many of these loads, while still providing reliable protection to the circuit it is installed on. The unit is also UL Listed and meets or exceeds all relevant industry standards, such as UL 489, UL 1077, and UL 1053.

The 3120-F521-P7T1-W19DG4-16A is an ideal choice for residential and commercial applications, offering reliable protection and reliable performance. It is also a cost-effective solution for many applications due to its small size and lower cost. Whether you are looking for a reliable solution for a single-phase or a three-phase system, the 3120-F521-P7T1-W19DG4-16A is an ideal and cost-effective choice.
