209-3-39703-1

A circuit breaker is an electrical switch that disconnects a circuit from a power source when a predetermined current is exceeded. The 209-3-39703-1 circuit breaker is used in a variety of applications, from residential to industrial. It is a 3-pole thermal magnetic circuit breaker with a 400A frame size.

In residential applications, the 209-3-39703-1 is used in main panel and service panel applications. It is often used as the main circuit breaker in the main panels, as it provides protection against overloads and short circuits. It is also a great choice for service panel usage, as it can be used to protect circuits associated with multiple appliances and motors in the home.

The 209-3-39703-1 is also an ideal choice for industrial applications. It is frequently used in the process industry, such as food and beverage industries, as the main circuit breaker for plant protection. Its thermal magnetic protection ensures quick response in the case of short circuits, protecting the plant and its resources. In the manufacturing industry, it is used to protect circuits associated with motors, pumps, and other equipment.

The 209-3-39703-1 circuit breaker works by using a combination of thermal and magnetic sensing mechanisms. The thermal protection trips the circuit breaker when a current is detected that exceeds the predetermined threshold. The magnetic protection is designed to kick in when the current is too high for the thermal protection to handle. The 209-3-39703-1 trips quickly, reducing the risk of equipment damage caused by overloads or short circuits.

The 209-3-39703-1 circuit breaker is a reliable and cost-effective solution for a variety of applications. It is designed to provide reliable overcurrent protection and is available in a variety of amperage ratings to meet the needs of the application. Additionally, it is a great choice for protection against accidental contact with energized conductors. Its quick response time is beneficial for preventing further damage to the equipment, making it a great choice for industrial and residential applications.
