MOREDAY AC Moulded Case Circuit Breaker New 1p 2p 3p 4p Mccb 125amp

A moulded case circuit breaker, abbreviated as MCCB, is an electrical protection device that can be used in a wide voltage range, at frequencies of 50 Hz and 60 Hz. The main difference between molded case circuit breakers and miniature circuit breakers is that MCCBs are rated up to 2,500 amps, and their trip settings are often adjustable. Another difference is that MCCBs tend to be much larger than MCCBs. Like most circuit breaker types, MCCBs have three main functions:

Detail

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. MCCBs are 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.

MDM1 series molded case circuit breaker, rated voltage up to AC1000V, current up to 400A. AC800V voltage breaking capacity up to 30kA, can realize the system short circuit protection.

Equipped with the protection devices for over-current, short circuit and under voltage, the product is capable of preventing damage of circuits and supply units. The product conforms to IEC60947-2 standard.
