Description
630 Amp 3 Pole MCCB
The 630 Amp molded case circuit breaker, abbreviated as 630 Amp MCCB, is an electrical protection device that can be used for various voltages and frequencies of 50 Hz and 60 Hz.
The main distinctions between molded-case and miniature circuit breakers are that the MCCB can have current ratings of up to 2,500 amperes, and its trip settings are normally adjustable.
An additional difference is that MCCBs tend to be much larger than MCBs. As with most types of circuit breakers.
630 Amp MCCB has three main functions
- Protection against overload – currents above the rated value that last longer than what is normal for the application.
- Protection against electrical faults – During a fault such as a short circuit or line fault, there are extremely high currents that must be interrupted immediately.
- Switching a circuit on and off – This is a less common function of circuit breakers, but they can be used for that purpose if there isn’t an adequate manual switch.
The wide range of current ratings available from molded-case circuit breakers allows them to be used in a wide variety of applications.
630 Amp MCCB is available with current ratings that range from low values such as 15 amperes to industrial ratings such as 2,500 amperes.
This allows them to be used in both low-power and high-power applications.
