MCBs
MCB 斷路器（又稱「微型斷路器」、「小型漏電斷路器」），是一種用來保護電路超負載（漏電）的裝置。當MCB斷路器檢測到電流超過電路所能承受的最高值時，它便會自動斷開電路，從而防止電線、電器、和其他裝置因電流過載而受到損毀。
MCB斷路器的類型
MCB 斷路器有多種類型，其中最常見的包括 B 型、C 型和 D 型。不同類型的MCB 斷路器均有其各自可承受的最高電流負載水平：
B 型：通用型，適用於普通家庭使用，最高可承受3 至 5 倍的負載電流。
C 型：適用於電流較高的設備，如電動機和變壓器，最高可承受5至 10 倍的負載電流。
D 型：專門用於需要有大功率電流的裝設，最高可承受10至 20 倍的負載電流。
MCB微型斷路器的用途
MCB微型斷路器被廣泛應用在建築、住宅和工業的電力分配系統中，在防止電流負載及保護設備受損方面發揮着極大的作用。MCB微型斷路器是現代電力安裝的基本元素，它增強了電力系統的可靠性和安全性。
MCB微型斷路器的規格
除了最高可承受的電流負載水平外，MCB微型斷路器亦會按以下因素而衍生出不同規格：
- 電流評級：常見有 6A、10A、16A、20A、32A、40A、50A 等，適合不同負載電流。
- 電壓等級：例如 230/400V、415V等，會根據電壓而有所不同。
- 中斷容量：表示斷路器可安全關斷的最大短路電流，是一個重要的安全指標。
- 極數和電流類型：可根據極數和使用的電流類型而分成直流、單極、和雙極微型斷路器
- 尺寸和安裝方式：不同斷路器可配合不同的電板空間和安裝軌道。
- 配件兼容性：某些型號可與輔助接觸器、警報接觸器等配件，以增加系統功能的靈活性。

關於MCB斷路器的常見問題
MCB斷路器的跳脫機制是什麼？
MCB 斷路器通常採用熱磁脫扣機制。熱元件會對長時間的過電流狀態作出反應，而磁性元件則對短路電流作出反應。
MCB斷路器可以安裝在哪裏？
MCB 斷路器安裝於配電板或用戶單元中，一般會與剩餘電流裝置（RCD）一起使用，以增強電力供應的安全。
我可以重置MCB斷路器嗎？
MCB 斷路器在過電流跳脫後，通常可以手動重置。然而，在重置之前，記得要調查並處理過電流的原因，以避免潛在的危險。
