Molded case circuit breakers are also known as device type circuit breakers. All components are sealed in a plastic housing. Auxiliary contacts, undervoltage release and shunt release are modular. Due to the very compact structure, the molded case circuit breaker is basically inaccessible. It is mainly manual, and large capacity can be selected for power supply. Due to the application of electronic overcurrent trip, molded case circuit breaker can also be divided into class A and class B. class B has good protection characteristics, but due to price factors, thermal magnetic release is used. Class a products have a high market share.

塑殼斷路器在塑料外殼中配備有觸點，滅弧室，跳閘單元和操作機構，通常不考慮維護，適用于分支電路的保護開關和過電流釋放裝置有一個熱磁場。無論是型式還是電子式，一般的熱磁塑殼斷路器都是非選擇性斷路器，只有過載長延時和短路瞬時保護。電子塑殼斷路器具有過載長延時和短路。四種保護功能：延遲，短路瞬態和接地故障。一些新的電子塑殼斷路器還具有區域選擇性鏈功能。大多數塑殼斷路器是手動操作的，有些具有電機操作機構。

The molded case circuit breaker is equipped with contacts, arc extinguishing chamber, tripping unit and operating mechanism in the plastic shell. Generally, maintenance is not considered. The protective switch and overcurrent release device suitable for branch circuit have a thermal magnetic field. Regardless of the type or electronic type, the general thermal magnetic molded case circuit breaker is a non selective circuit breaker with only overload long-time delay and short-circuit instantaneous protection. The electronic molded case circuit breaker has overload, long time delay and short circuit. Four protection functions: delay, short circuit transient and ground fault. Some new electronic molded case circuit breakers also have area selective chain function. Most molded case circuit breakers are manually operated, and some have motor operating mechanisms.

結論：關于abb塑殼斷路器今天小編就這么說了，這臺斷路器在我們的工業生產中很常見，所以我們從來沒有聽說過它在日常生活中也就不足為奇了。但是在這篇文章中做一個簡單的理解是沒有害處的，也許我們將來會使用它。那么我們生活中通常會使用什么斷路器呢？我們在日常生活中使用稱為空氣開關的斷路器。

Conclusion: that's what Xiao Bian said about ABB molded case circuit breaker today. This circuit breaker is very common in our industrial production, so it's not surprising that we have never heard of it in our daily life. But there is no harm in making a simple understanding in this article. Maybe we will use it in the future. So what circuit breaker do we usually use in our life? We use circuit breakers called air switches in our daily life.
