Web7 apr. 2024 · The MCB and MCCB are two types of circuit breakers used for different applications. The MCB is a compact device that provides protection against overloads and short circuits in low-voltage electrical systems. These circuit breakers have a rated current of up to 125A and are commonly used in residential and commercial applications. WebAn MCCB or Molded Case Circuit Breaker is a modular device used to protect a piece of low voltage equipment or circuit from overload and short circuits. Apart from overloads and short circuits, specially designed MCCBs can protect against ground faults …
WebSelectivity is determined from the let through energy I 2 t characteristics.. The selectivity limit current is the value at which the total operating I 2 t of the downstream fuse exceeds the pre-arcing I 2 t of the upstream fuse.. In the short-circuit zone the let through energy of a fuse is constant and therefore the comparison may be made from the tabulated figures … WebMCCB (Molded Case Circuit Breaker) คือเซอร์กิตเบรกเกอร์ที่ห่อหุ้มปิดมิดชิดด้วย molded จำนวน 2 ส่วน ที่ทำการทดสอบ Dielectric strength ก่อนที่จะวางจำหน่าย ส่วน molded ทำหน้าที่เป็นฉนวนหุ้มปกปิดเซอร์กิตเบรคเกอร์ ส่วนใหญ่ทำจาก phenolic
