Circuit Breakers are safety devices used in electric power systems to help protect and isolate parts of a system from damage caused by excess current. 4120-G217-J1M1-M6S5ZN-10A is a type of circuit breaker designed for medium voltage applications. It is designed to provide reliable circuit protection in residential, commercial and industrial applications.

Application Field

4120-G217-J1M1-M6S5ZN-10A is a type of medium voltage circuit breaker that is designed for use in industrial and commercial applications. It is suitable for use at voltages up to 6kV and can be used as a main, tie, or motor circuit breaker. It offers excellent protection for feeders, transformers, motors, and other medium-voltage equipment. It is also suitable for branch circuit protection where fuses are too slow or could be unreliable.

The 4120-G217-J1M1-M6S5ZN-10A circuit breaker is designed to be used in applications that require the highest protection and reliability. It is ideal for use in applications such as power generation plants, substations, and industrial control panels. It is also suitable for use in marine and offshore applications.

Working Principle

The 4120-G217-J1M1-M6S5ZN-10A circuit breaker is designed to detect an overcurrent fault and interrupt the circuit automatically. This is achieved by monitoring the current flow through the circuit and using an electromechanical tripping device to trip the breaker. The tripping device is activated when the current in the circuit exceeds the rated interrupting capability of the breaker. When the fault current is sensed, the tripping device will activate and cause the contacts in the breaker to open and interrupt the circuit.

The 4120-G217-J1M1-M6S5ZN-10A circuit breaker also features an adjustable trip setting, which allows the user to adjust the current levels at which the breaker will trip. This setting can be adjusted to ensure the breaker trips at the appropriate current levels, depending on the application requirements. The adjustable trip feature also allows the user to customize the breaker to fit their particular application.

The 4120-G217-J1M1-M6S5ZN-10A circuit breaker also features a thermal overload protection device. This device detects when the current in the circuit exceeds the rated value and is then able to detect and activate the trip at the correct time, preventing the circuit from being damaged due to excess current. The thermal overload device is designed to shut off the power and prevent damage to the circuit.

The 4120-G217-J1M1-M6S5ZN-10A circuit breaker is designed to be both safe and reliable. It features a high level of electrical protection and can be used in applications that require the highest levels of protection and reliability. It is ideal for use in industrial and commercial applications, offering excellent protection for feeders, transformers, motors, and other medium-voltage equipment.
