Circuit breakers are a common type of electrical device used to protect homes, businesses, and industrial facilities from overloads, short circuits, and ground faults. The most common type of circuit breaker, the 991310, has been around for decades and is used in many applications. This article will discuss the 991310’s application field and working principle.

991310 Application Field

The 991310 circuit breaker is an electromechanical device that is used to protect circuits from receiving too much current. It can be used to protect a single device, such as an air conditioner, or an entire electrical system. It is commonly used in industrial and residential applications, such as in houses and factories. The 991310 is especially popular as a distribution panel breaker, as it can protect a circuit from overloads and short circuits.

991310 Working Principle

The 991310 circuit breaker uses a metal strip or “trip unit” to detect when a current has exceeded a certain level. If the current reaches a point that could cause damage to the circuit or the equipment that it is connected to, the metal strip will heat up due to the potential energy and will rapidly expand, breaking the circuit and stopping the current. The 991310 has adjustable limits, so the user can decide at what point the metal strip should expand. After the current has been stopped, the user can reset the breaker and the current will start flowing again.

Conclusion

The 991310 circuit breaker is a versatile device that is used to protect circuits and equipment from too much current. It is commonly used in both residential and industrial applications, and it is especially popular as a distribution panel breaker. The 991310 uses a metal strip that can quickly expand when the current reaches a certain level, breaking the circuit and preventing overloads and short circuits.
