Electrical MCBs (Miniature Circuit Breakers) and MCCBs (Molded Case Circuit Breakers) are essential protective devices used to safeguard electrical circuits from overloads and short circuits.

MCBs: These are compact, automatic switches designed to protect low-voltage circuits from overcurrent conditions. They are ideal for residential and small commercial applications, providing fast tripping and easy reset capabilities. MCBs are typically rated for lower current capacities and offer reliable overload protection and short-circuit protection.
MCCBs: These are larger, more robust breakers designed for medium to high-voltage applications. They offer adjustable trip settings and are used in industrial and large commercial installations to protect high-current circuits. MCCBs provide overload protection, short-circuit protection, and often feature additional functions like ground fault protection and selective coordination.

Both MCBs and MCCBs are crucial for ensuring electrical safety, enhancing system reliability, and protecting electrical infrastructure.
