MCCB
Understanding MCCB (Moulded Case Circuit Breaker): A Complete Guide Electricity is the backbone of modern infrastructure, and with it comes the responsibility of ensuring safety, efficiency, and reliability. One such vital device used in power distribution and protection systems is the MCCB (Moulded Case Circuit Breaker). In this blog, let’s explore what MCCB is, how it works, its features, applications, and why it is preferred over traditional fuses and MCBs in higher rating systems. 🔌 What is an MCCB? MCCB stands for Moulded Case Circuit Breaker. It is an electrical protection device that can handle: Higher current ratings (typically above 100A up to 2500A). Adjustable trip settings for overload and short-circuit protection. Protection against overload, short circuit, and earth fault conditions. Unlike an MCB (Miniature Circuit Breaker), which is limited to lower currents (generally up to 100A), MCCBs are designed for industrial and commercial applications where large power ha...
