A circuit breaker is an electrical device that is used to protect an electrical circuit from excessive current. The 4130-G411-K4M1-70A circuit breaker is a specific model that is manufactured by a company called A-Power. This particular model is a double pole circuit breaker with two independent trip units. It is primarily used in applications where two separate electrical systems are linked to the same source.

The 4130-G411-K4M1-70A circuit breaker has a rated current of 70A (Amps) and a rated voltage of 120 and 240 volts. It has an adjustable fixed current rating of 0.5-6.5A and a thermal rating of 10kA. It is designed for use with three wires, namely Line, load and ground. It also has an adjustable short-time and instantaneous trip setting, making it suitable for a variety of applications.

The 4130-G411-K4M1-70A circuit breaker\'s main purpose is to protect electrical systems from overload, short circuits and general over-current, and to protect people from the risk of electrical shock. It detects an overload or short circuit in the circuit, and automatically trips and breaks the circuit, thus preventing the current from exceeding the rated value.

Due to its two independent trip units, the 4130-G411-K4M1-70A circuit breaker can be used in dual circuits, namely a 120-volt main and a secondary 240-volt circuit. It is also suitable for controlling motor loads, lighting circuits and other equipment. Furthermore, it is capable of handling high inrush currents, making it an ideal choice for appliances with large motors, such as air conditioners and refrigerators.

4130-G411-K4M1-70A circuit breaker is designed for use in a range of environments, both indoors and outdoors. It is suitable for residential, commercial and industrial applications, as well as marine applications. It is UL (Underwriters Laboratories) listed and CSA (Canadian Standards Association) approved, therefore it meets all the safety requirements in both countries. In addition, it is designed to meet the requirements of both UL 489 and UL 1077 for protective device coordination.

In conclusion, the 4130-G411-K4M1-70A circuit breaker is a reliable solution for protecting two independent circuits from over-current and short circuit situations. It has an adjustable fixed current rating, adjustable short-time and instantaneous trip setting, and is UL and CSA listed. It is suitable for a range of applications, including residential, commercial, industrial and marine applications. It is also capable of handling high inrush currents from large motors, and is designed to meet the requirements of both UL 489 and UL 1077 for protective device coordination.
