MCB is an abbreviation for Miniature Circuit Breaker. These circuit breakers perform the vital role of breaking the circuit to prevent damage from excessive current due to short circuit or overload.
When a short circuit occurs, a large amount of current begins to flow causing the MCB to trip almost immediately. In the event of an overload, it takes a few seconds to trip and interrupt the circuit.
Overloading and short circuits in the power supply can be dangerous for both people and equipment. To minimize these risks, MCBs are installed.
PressFit’s SFT1 MCBs come with current ratings from 6A to 63A and high short circuit breaking capacity of 10kA. SFT1 circuit breakers adhere to the IS/IEC 60898-1 norms and are perfect fit for your heavy electrical appliances.
MCBs are more sensitive to current than a fuse. As soon as they discover anomalies, they immediately trip and interrupt the circuit. They can also be reset after tripping, which is a huge advantage over fuses. It is one of the main reasons why we are using mcb over a fuse today.
