接触器是一种自动化的通断电器，主要用于频繁接通、断开电路，可适应于不间断的工作制，并具有较高的操作频率，且可以在恶劣的工作环境下使用。接触器分为交流接触器和直流接触器，交流接触器型号由文字符号、数字部分、字母部分组成。A12-30-10-84数字部分表示主电路的额定工作电流，字母部分表示控制电路的额定工作电流。

加在交流接触器上的电器元件叫辅助触头组。

A12-30-10-84辅助触头组也叫辅助开关，型号有F4-22等多种，F4系列有二极和四极两种，该辅助触头组和交流接触器或接触器组合后能扩展辅助触点的数量。

A12-30-10-84通断电器，也叫开关模块，可以非常方便地接入家中原有开关、插座、灯具、电器的线路中，通过手机App或者语音即可控制电路通断，轻松实现原有家居设备的智能化改造。通断器原理比较简单，结构原理拆机图可以看得很清楚，基本由外壳+PCBA组成。通断器常见的基础功能基本包含：开关、定时、倒计时等功能。

电路断电器有高压断路器和空气断路器两种。

A12-30-10-84高压断路器，又称高压开关，它不仅可以切断或闭合高压电路中的空载电流和负荷电流，而且当系统发生故障时，通过继电保护装置的作用，切断过负荷电流和短路电流。它具有相当完善的灭弧结构和足够的断流能力。

空气断路器（自动开关），它用手动（或电动）合闸，用锁扣保持合闸位置，由脱扣机构作用于跳闸并具有灭弧装置的低压开关，可以在电路内发生过负荷、短路、电压降低或消失时，能自动切断电路。

Contactor is an automatic on-off electrical device, mainly used for frequent on and off circuits, can be adapted to uninterrupted work, and has a high operating frequency, and can be used in harsh working environments. The contactor is divided into AC contactor and DC contactor, and the type number of the AC contactor is composed of a text symbol, a number part and a letter part. A12-30-10-84 The number part indicates the rated working current of the main circuit, and the letter part indicates the rated working current of the control circuit.

The electrical element added to the AC contactor is called the auxiliary contact group.

A12-30-10-84 Auxiliary contact group is also called auxiliary switch, models F4-22 and other, F4 series has two poles and four poles, the auxiliary contact group and AC contactor or contactor combination can expand the number of auxiliary contacts.

A12-30-10-84 on-off electrical appliances, also known as switch modules, can be very convenient access to the original switches, sockets, lamps, electrical lines in the home, through the mobile phone App or voice can control the circuit on and off, easy to achieve the intelligent transformation of the original home equipment. The principle of the on-off device is relatively simple, and the structure principle disassembly diagram can be seen clearly, which is basically composed of the shell +PCBA. The common basic functions of the breaker include: switching, timing, countdown and other functions.

The circuit breaker has two kinds of high voltage circuit breaker and air circuit breaker.

A12-30-10-84 High voltage circuit breaker, also known as high voltage switch, it can not only cut off or close the no-load current and load current in the high voltage circuit, but also when the system fails, through the role of the relay protection device, cut off the overload current and short circuit current. It has quite perfect arc extinguishing structure and sufficient current cutting capacity.

Air circuit breaker (automatic switch), it uses manual (or electric) closing, with the lock to maintain the closing position, by the trip mechanism acting on the trip and with the arc extinguishing device of the low-voltage switch, can occur in the circuit overload, short circuit, voltage reduction or disappearance, can automatically cut off the circuit.
