The main types of circuit breakers are: molded case circuit breaker, plastic case circuit breaker, leakage circuit breaker, miniature circuit breaker, high section miniature leakage circuit breaker, high section miniature leakage circuit breaker, miniature leakage circuit breaker, lighting distribution box, dual power automatic switching device and intelligent universal circuit breaker.

塑殼斷路器有10型M1型DZ15\DZ20型還有DZ15LEDZ20LEDZ18。塑殼斷路器能夠在電流超過(guò)跳脫設(shè)定后自動(dòng)切斷電流。

Molded case circuit breakers include 10 type, M1 type, dz15 \ DZ20 type and dz15ledz20ledz18. The molded case circuit breaker can automatically cut off the current when the current exceeds the tripping setting.

塑殼指的是用塑料絕緣體來(lái)作為裝置的外殼，用來(lái)隔離導(dǎo)體之間以及接地金屬部分。

Plastic shell refers to the use of plastic insulator as the shell of the device, which is used to isolate between conductors and grounded metal parts.

塑殼斷路器通常含有熱磁跳脫單元，而大型號(hào)的塑殼斷路器會(huì)配備固態(tài)跳脫傳感器。其脫扣單元分為：熱磁脫扣與電子脫扣器。

Molded case circuit breakers usually contain thermal magnetic trip units, while large models of molded case circuit breakers will be equipped with Solid-state trip sensors. The tripping unit is divided into thermal magnetic tripping and electronic tripping.

常用的，額定電流共有以下幾種1525304050607580100125160200225250315350400500630A。

The common rated currents are 1525304050607580100125160200225250315350400500630a.

塑殼斷路器，在電路中作接通、分?jǐn)嗪统休d額定工作電流，并能在負(fù)載發(fā)生過(guò)載、短路、欠壓的情況下進(jìn)行可靠的斷路保護(hù)。

The molded case circuit breaker can make, break and carry the rated working current in the circuit, and can carry out reliable breaking protection in case of overload, short circuit and undervoltage.

斷路器的動(dòng)、靜觸頭及觸桿設(shè)計(jì)成平行狀，利用短路產(chǎn)生的電動(dòng)斥力使動(dòng)、靜觸頭斷開(kāi)，分?jǐn)嗄芰Ω撸蘖魈匦詮?qiáng)。

The dynamic and static contacts and contact rods of the circuit breaker are designed in a parallel shape. The dynamic and static contacts are disconnected by using the electric repulsion generated by short circuit, with high breaking capacity and strong current limiting characteristics.
