Product Description

A Molded Case Circuit Breaker, abbreviated MCCB, is a type of electrical protection device that can be used for a wide range of voltages, and frequencies of both 50 Hz and 60 Hz. The main distinctions between molded-case and Miniature Circuit Breaker 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, an 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. 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.

KNM6 series moulded case Circuit Breaker applies at the circuit of AC 50/60Hz,rated operation voltage of 600V(690V)and below, DC250V and below and rated current of from 12.5A up to 800A to distribute the electric power, and performs the low frequency of opening and closing under normal condition and the overload protection, short-circuit protection and under-voltage protection. The circuit breaker with a rated current of frame of 400A and below could also perform the low frequency of starting of the squirrel- cage motor and the protection in terms of operation breaking, and protect the motor in terms of overload, short circuit and under-voltage.
This product conforms to the requirement of IEC60947-2, GB14048.2 standards.
