Question:
contactors, relays, circuit breakers of the difference? ? ? Mody able to elaborate?
Answer:
Hello!
relays, contactors should be said that the same type of device, through the coil to achieve a small current-controlled high-current role. Generally used in electrical automatic control loop.
circuit breaker is commonly said that the automatic switching is a switching device, it has a breaking load current role.
Answer:
1, contactors, relays, circuit breakers can be regarded as on-off switch control circuit; two contact with electrical equipment typically used as a remote, automatic and so the main circuit control; relay normally used as the signal, the main circuit control and protection of the secondary circuit, circuit breakers typically installed in the main circuit and control power off, and can this circuit under-voltage, over current, short circuit protection, can also be low-power devices under the direct control of non-frequent start. 3 Because of these three devices use a variety of performance categories numerous examples can not be 11, roughly as described above respectively.
Answer:
of the most popular talk
contactor coil gains and losses by controlling electrical control circuit for controlling motor thermal protection relay
Following the general principles and is a two-metal contact device used in conjunction with
circuit breaker control protection circuit overload and short circuit protection in general
these three is the motor control loop in the San Dajian
Answer:
Hello:
in the production and life applications, to complete a use of electrical appliances start-stop process, the used circuit breakers, contactors, protector of the.
first circuit breaker, (equivalent to Knife) is a master switch of the circuit.
followed by the contactor, the main role is to connect and disconnect the circuit can realize long-distance operation.
at times is to protect the device, the main role is to prevent equipment overload, in the safety equipment fault conditions can quit. Is such that you do understand.
Chinese:接触器，继电器、断路器的区别？？？

问题:
接触器，继电器、断路器的区别？？？能详细些么？
回答:
你好！
继电器，接触器应该说是同一类型的器件，通过线圈而达到小电流控制大电流的作用。一般使用在电气的自动控制回路上。
断路器就是通常说的自动开关，是一种开关器件，它具有分断负载电流的作用。
回答:
1，接触器，继电器，断路器都可以看作是控制电路通断的开关；2，接触器通常用来在电器设备上作为远程，自动等主电路的控制；继电器一般用做信号，主电路二次回路的控制和保护，断路器一般安装在主电路中，控制电源的通断，并可对此电路进行欠压，过流，短路进行保护，也可在小功率下对设备进行不频繁启动的直接控制。3由于这三种设备的各种性能用途分类繁多无法一一例举，大致分别就如上所述。
回答:
最通俗的讲
接触器 控制用 靠线圈得失电控制 用于控制电机回路
继电器 保护用 热继一般是双金属片原理 和接触器配合使用
断路器 控制保护电路 一般过载和短路保护
这3个是电动机控制回路中的三大件

你好：
在生产生活应用中，完成一个用电器的起停过程，就用到断路器、接触器、保护器了。
首先是断路器，（相当于刀闸）是该电路的总开关。
其次是接触器，主要作用是接通和断开电路，可实现远距离操作。
在次之是保护器，主要作用是防止设备超负荷、在故障情况下能使设备安全退出。就是这样，你明白了吗。
