Circuit breakers are an important component of the electricity grid, used to protect electrical circuits from dangerous levels of power surges. The 209-1-31988-20 is a circuit breaker specifically designed for high-temperature applications. This article will discuss the application field of the 209-1-31988-20 as well as its working principle.

Application Field

The 209-1-31988-20 circuit breaker is designed to operate in high-temperature applications. This means that it can handle temperatures ranging from 40°C (104°F) to 105°C (221°F). It is suitable for use in power grids, residential and commercial buildings, and industrial facilities. It can also be used in photovoltaic systems and other electrical systems where high temperatures are likely to be encountered.

Working Principle

The 209-1-31988-20 circuit breaker uses a thermal overload device to detect overloads. This overload device senses an overload when the current in the circuit exceeds the maximum allowed current rating. When this happens, the overload device trips, disconnecting the circuit from the power source and preventing further damage. The thermal overload device is adjustable, allowing the maximum current rating to be adjusted to different levels.

The 209-1-31988-20 also has an arc-fault detection capability. When an arc-fault is detected, the circuit breaker trips and disconnects the circuit, preventing further arcing or sparking that could cause a fire. The arc-fault detection also helps to protect the circuit breaker from mechanical and thermal damage.

The 209-1-31988-20 is designed to detect and trip fast, preventing any additional damage. It also has an alarm system that alerts users to any faults or overloads in the circuit. This alarm system can be set to an audible or visual signal when an overload or short circuit is detected in the circuit.

The 209-1-31988-20 is designed to be durable and reliable. It can withstand high levels of vibration, temperature, humidity, and ozone concentrations without any significant degradation.

In summary, the 209-1-31988-20 is a circuit breaker specifically designed for high-temperature applications such as power grids, residential and commercial buildings, and industrial facilities. It features a thermal overload device, an arc-fault detection capability, and an alarm system. It is designed to be durable, reliable, and to trip fast in the case of an overload or arc-fault.
