A circuit breaker is a device used in electrical networks, mainly for the purpose of protecting circuits from short-circuits and other over-current conditions, although it can also provide isolation when necessary. The 3120-F623-P7T1-W19FG4-7A falls under the category of circuit breakers, and its application field and working principle are discussed below.

Application Field

The 3120-F623-P7T1-W19FG4-7A is designed for general-purpose use in residential, commercial and industrial applications. It can be used to protect motors and other loads that may require high-capacity protection. The 3120-F623-P7T1-W19FG4-7A is rated for 600 volts and is UL 1077 listed for screw-in type circuit breakers.

Working Principle

The 3120-F623-P7T1-W19FG4-7A works on the principle of electrical separation. When a circuit becomes overloaded, the breaker detects the imbalance in the electricity flowing through it and trips the circuit to protect against damage. The breaker has a set of contacts that open automatically when the excess current flowing through it reaches a certain threshold. This interrupts the electricity flow and cuts off power to the overloaded circuit.

The 3120-F623-P7T1-W19FG4-7A uses a thermal-magnetic system that consists of a heat-responsive element and a voltage-responsive element. The heat-responsive element is used to detect the heat generated by an overload, while the voltage-responsive element trips the breaker when an excessive current flows through the circuit. The 3120-F623-P7T1-W19FG4-7A also has a manual reset switch that can be used to reset the circuit breaker after it has been tripped.

The 3120-F623-P7T1-W19FG4-7A has multiple feature combinations, including adjustable trip settings, interchangeable trip elements, and adjustable trip range. The breaker also features a compact design that allows for easy installation. Additionally, the breaker has an LED that indicates when the breaker has been tripped, and it is compatible with a wide range of panel boards, load centers, and load breakers.

Conclusion

The 3120-F623-P7T1-W19FG4-7A is a circuit breaker designed for general-purpose use in residential, commercial, and industrial applications. It operates on the principle of electrical separation, using a thermal-magnetic system with adjustable trip settings. The 3120-F623-P7T1-W19FG4-7A also has an LED indicator, a manual reset switch, and is compatible with a wide range of panel boards, load centers, and load breakers.
