              小型斷路器和塑殼斷路器有什么區別?

              What is the difference between miniature circuit breaker and molded case circuit breaker?
              作為短路器的一種,小型斷路器和塑殼斷路器在現在的生活乃至工業中都得到了廣泛的應用,那么兩者有什么區別呢?
              As a kind of short circuit breaker, miniature circuit breaker and molded case circuit breaker have been widely used in life and even industry. What is the difference between them?
              對于小型斷路器和塑殼斷路器都有一個清晰的了解,下面給大家詳細介紹。
              I have a clear understanding of miniature circuit breaker and molded case circuit breaker, which will be introduced in detail below.
              小型斷路器又稱微型斷路器,適用于交流50/60Hz額定電壓230/400V,額定電流至63A線路的過載和短路保護之用,也可以在正常情況下作為線路的不頻繁操作轉換之用。
              Miniature circuit breaker, also known as miniature circuit breaker, is suitable for overload and short circuit protection of AC 50 / 60Hz, rated voltage 230 / 400V and rated current up to 63A lines, and can also be used for infrequent operation and conversion of lines under normal conditions.
              小型斷路器主要用于工業、商業、高層和民用住宅等各種場所。
              Miniature circuit breakers are mainly used in various places such as industry, commerce, high-rise and civil residence.
              塑殼斷路器能夠在電流超過跳脫設定后自動切斷電流。塑殼指的是用塑料絕緣體來作為裝置的外殼,用來隔離導體之間以及接地金屬部分。
              The molded case circuit breaker can automatically cut off the current when the current exceeds the tripping setting. 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.
              小型斷路器和塑殼斷路器有什么區別:
              What is the difference between miniature circuit breaker and molded case circuit breaker:
              1、塑殼斷路器DCMIL-630型(附件)警聲模塊能接入較粗導線,如35平方以上的。小型斷路器只適合接10平方以下的導線。
              1. Dcmil-630 (accessory) alarm sound module of molded case circuit breaker can be connected with thicker wires, such as those with an area of more than 35 square meters. Miniature circuit breakers are only suitable for connecting wires less than 10 square meters.
              2、塑殼斷路器塑殼斷路器端頭用螺母聯接,容易壓緊,接觸良好。小型斷路器采用較小的壓緊端子端子DJ623-8,且只能用螺絲刀擰緊,力矩不夠,不容易壓緊,接觸不太好。
              2. Molded case circuit breaker the end of molded case circuit breaker is connected with nut, which is easy to compress and has good contact. The miniature circuit breaker adopts a smaller compression terminal dj623-8, which can only be tightened with a screwdriver. The torque is not enough, it is not easy to compress and the contact is not very good.
              3、塑殼斷路器對過流和短路采用兩套裝置分別保護,過流保護動作值可以人工調整。小型斷路器對過流和短路共用一套裝置,電流不可調。
              3. Molded case circuit breaker adopts two sets of devices to protect overcurrent and short circuit respectively, and the action value of overcurrent protection can be adjusted manually. The miniature circuit breaker shares a set of device for overcurrent and short circuit, and the current is not adjustable.
              4、塑殼斷路器相間距離大,且有滅弧罩,滅弧能力強,能承受更大的短路電流,還不易引發相間短路。壽命也長。
              4. The molded case circuit breaker has large phase to phase distance and arc extinguishing cover, which has strong arc extinguishing ability, can withstand greater short-circuit current and is not easy to cause phase to phase short circuit. Long life.
              5、小型斷路器動作靈敏度比塑殼斷路器高。
              5. The action sensitivity of miniature circuit breaker is higher than that of molded case circuit breaker.
