Circuit breakers are devices used to protect electrical circuits from damage due to short-circuiting, overloads, or other dangerous situations. The global circuit breaker market is estimated to exceed $14 billion USD by the year 2021. In this article, we will examine the application field and working principle of a popular circuit breaker, the 209-2-39663-2.5-V.

The 209-2-39663-2.5-V circuit breaker is a popular and versatile product typically used in residential, commercial, and industrial applications. It is a thermal-magnetic type breaker, meaning it has two types of protection against overloads: thermal protection and magnetic protection.

The thermal protection component helps protect against heat buildup caused by an overload. This is done by using a heating element that is mounted to the moving contact of the breaker. As the current increases, more heat is generated and the heating element expands, pushing the moving contact further away from the other contact until the circuit is opened. This prevents further heat buildup and the potential for damage due to prolonged high-currents.

The magnetic protection component helps protect against sudden overloads or short-circuits. It works by using an electromagnet that is mounted to the moving contact of the breaker. When an overload or short-circuit occurs, the electromagnet is activated and the current forces the moving contact away from the other contact, opening the circuit and preventing further damage.

The 209-2-39663-2.5-V circuit breaker is designed for use with direct current (DC) systems and is suitable for use in currents of up to 2500V. It features both manual and automatic resetting and is designed to trip in 120 milliseconds after detecting an overload or short-circuit. This ensures that the breaker will respond quickly enough to prevent damage, while also providing a fast reset time to allow the system to return quickly to operation. The 209-2-39663-2.5-V also has a built in thermal memory feature which allows it to remember the highest current it has seen and ensure that it does not trip again until the current reaches a much higher level.

In summary, the 209-2-39663-2.5-V circuit breaker is a popular product that is typically used in residential, commercial, and industrial settings. It is a thermal-magnetic type breaker, meaning that it features both thermal and magnetic protection against overloads and short-circuits. It is designed for use with DC systems and can handle currents up to 2500V. It features both manual and automatic resetting and has a built in thermal memory feature for improved efficiency. This product is a great choice for those looking for reliable and effective protection against electrical dangers.
