Circuit breakers are an important part of electrical safety systems that protect a site from overloads, shorts, and ground faults. The ATR11-D-X-63-WB-5.0A circuit breaker is a popular device used in a wide range of applications, from small households to industrial facilities. In this article, we will discuss the application field and working principle of the ATR11-D-X-63-WB-5.0A circuit breaker.

The ATR11-D-X-63-WB-5.0A is a double-pole, single-phase ac circuit breaker with a maximum continuous current rating of 5.0A. This device is suitable for applications ranging from residential to commercial and industrial installations, as well as for use in industrial control panels and other specialized circuits. In such applications, the ATR11-D-X-63-WB-5.0A is used to protect the equipment against overloads, shorts, and ground faults.

The ATR11-D-X-63-WB-5.0A circuit breaker is designed with a mechanism that senses the amount of current and voltage passing through the circuit and automatically opens the circuit if the current or voltage exceeds predetermined safety settings. The current-sensing contact in the circuit breaker consists of a bimetallic strip that bends and opens the contacts when the current reaches its set limit. The voltage-sensing contact uses a capacitor, which, when charged, expands to open the contact when the voltage reaches its set limit.

In addition to current- and voltage-sensing elements, the circuit breaker also contains a mechanical latch mechanism. This mechanism is used to hold the contacts in the closed position until the circuit breaker is manually reset or the current or voltage exceeds the set threshold. When the circuit breaker is tripped, the contacts open and the main power is disconnected, thus protecting the circuit from further damage.

The ATR11-D-X-63-WB-5.0A has several important features that make it a popular choice in many applications. Its compact size and slim form factor allow it to fit into tight spaces, making it well suited for installation in control panels and junction boxes. Furthermore, it is designed with switching diodes that enable it to perform in extreme temperature and humidity conditions. Additionally, the circuit breaker is designed to easily replace most legacy models, minimizing installation time and cost.

In summary, the ATR11-D-X-63-WB-5.0A circuit breaker is an important electrical safety device that is suitable for a range of applications, such as residential, commercial, and industrial installations. Its current- and voltage-sensing elements, along with its reliable latch mechanism, provide overcurrent and overvoltage protection. The device’s compact size, slim form factor, switching diodes, and easy-to-install design make it a great choice for a variety of applications.
