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.

塑壳断路器有10型M1型DZ15\DZ20型还有DZ15LEDZ20LEDZ18。塑壳断路器能够在电流超过跳脱设定后自动切断电流。

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.

塑壳指的是用塑料绝缘体来作为装置的外壳，用来隔离导体之间以及接地金属部分。

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.

塑壳断路器通常含有热磁跳脱单元，而大型号的塑壳断路器会配备固态跳脱传感器。其脱扣单元分为：热磁脱扣与电子脱扣器。

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，额定电流共有以下几种1525304050607580100125160200225250315350400500630A。

The common rated currents are 1525304050607580100125160200225250315350400500630a.

塑壳断路器，在电路中作接通、分断和承载额定工作电流，并能在负载发生过载、短路、欠压的情况下进行可靠的断路保护。

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.

断路器的动、静触头及触杆设计成平行状，利用短路产生的电动斥力使动、静触头断开，分断能力高，限流特性强。

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.
