219-2-6387-140

Circuit breakers are a critical component for many electrical systems. They are used to protect other components, such as switches, relays, and transformers, from electrical overloads, shorts, and other damage. The 219-2-6387-140 is a complex, multifunctional circuit breaker that offers a wide range of protection against overloads and short circuits. In this article, we will discuss the application field and working principle of the 219-2-6387-140 circuit breaker.

Application Field and Environments

The 219-2-6387-140 is designed for use in both industrial and commercial electrical systems. It is certified for indoor and outdoor applications, as well as hazardous locations. It can also be used in washdown applications, making it a great choice for applications in areas with a lot of moisture. Additionally, it is suitable for use in Class I Divisions 1, 2, and 3 environments.

Working Principle

The 219-2-6387-140 circuit breaker is designed to protect other components from dangerous overloads and short circuits. It is equipped with a thermal-magnetic trip mechanism, which provides two levels of protection. The thermal element monitors the current flow in the circuit and trips at a predetermined overload current level. The magnetic element senses the amount of energy stored in the circuit and trips if the current exceeds the set limit. Additionally, the circuit breaker has two independent settings for tripping: one for short circuit protection and one for overload protection.

The circuit breaker also includes a ground fault sensing feature, which can detect a ground fault and immediately trip the breaker before any serious damage is done to the system. This feature can be adjusted to trip at a certain current level, making it an effective way to protect devices from ground faults. Additionally, it has a magnetic latching feature, which allows the breaker to be snapped open or shut with a single push, eliminating the need for manual resetting.

Reconfigurable Options

The 219-2-6387-140 circuit breaker offers numerous reconfigurable options. It can be configured to trip on overload, ground fault, or both simultaneously. Additionally, the current settings can be adjusted to provide more or less protection, depending on the system requirements. Finally, the breaker can be configured to reclose after a trip, allowing the system to be reset more quickly.

Conclusion

The 219-2-6387-140 is a versatile, multifunctional circuit breaker that offers a wide range of protection against overloads and short circuits. It features a thermal-magnetic trip mechanism, ground fault sensing, and magnetic latching, and it also has numerous reconfigurable options. These features make it a great choice for a variety of industrial and commercial electrical systems.
