Molded Case Circuit Breaker (MCCB)
Molded Case Circuit Breaker, MCCB, is an electrical protection device to protect electrical circuits from damage by overcurrent. Prevents overload, short circuits, and switching of circuits. About ComPact Molded Case Circuit Breakers, MCCB. Protect cables sized for 100A to 3200 A. They now come in various sizes, intelligent metering, and monitoring, and with integrated earth leakage protection. Their highest breaking capacities allow them to protect also smaller cables when connected close to a powerful energy source.
MCCB uses a temperature-sensitive device, also known as a temperature element, with a current-sensitive electromagnetic device, also known as a magnetic element, to provide the trip mechanism for protection and isolation purposes. With this, it can ensure overload protection, prevent short circuits, and act as an electrical disconnector switch.
MCCB stands for "Molded Case Circuit Breaker." It is a type of circuit breaker used to protect electrical circuits and equipment from overcurrents, short circuits, and other electrical faults. MCCBs are commonly used in low-voltage electrical distribution systems and can handle higher current ratings than miniature circuit breakers (MCBs).
MCB (Miniature Circuit Breaker) and MCCB (Molded Case Circuit Breaker) are both types of circuit breakers used to protect electrical circuits from overcurrents and short circuits. While they serve the same purpose, there are several key differences between MCBs and MCCBs:
- Current Rating
- Application
- Construction and Size
- Trip Characteristics
- Short-Circuit Breaking Capacity (SCBC)
- Cost
- Overload and Short-Circuit Protection
In summary, the main differences between MCBs and MCCBs lie in their current-carrying capacity, application, size, construction, trip characteristics, and cost. MCBs are suitable for residential and light commercial use with lower current demands, while MCCBs are designed for industrial and commercial applications with higher current requirements.
