UP TO 400V 63A AC MINI CIRCUIT BREAKER IEC STANDARD
Circuit breakers are essential components in any electrical system. They prevent damage to electrical equipment and reduce the risk of fires by interrupting the flow of current when an overload or short circuit occurs. Without a reliable circuit breaker in place, your electrical system would be vulnerable to serious damage and even catastrophic failure.
An AC miniature circuit breaker (MCB) is a compact, electromechanical device designed to protect electrical circuits from excessive current flow. These breakers automatically disconnect the power supply when the current exceeds a predefined threshold, preventing damage to appliances and reducing the risk of electrical fires.
ACCORDING TO STANDARD IEC 60898-1
This standard applies to circuit breakers designed for residential and commercial applications. It covers aspects such as breaking capacity, temperature limits, and mechanical and electrical endurance.
UNIQUE CRAFT
BAD WEATHER POWER TO PROTECT THE FAMILY
To prevent short-circuit explosions, keep people away from danger.
ARC EXTINGUISHING SYSTEMKEEP AWAY FROM FIRE

After entering the arcing gate current, it is divided into many series arcs by the electromagnetic effect, which elongates, cools, and goes out.

COMPONENTS OF AN AC MINIATURE CIRCUIT BREAKER
An MCB consists of four main components:

Main contacts: These contacts form the connection between the input and output sides of the circuit breaker. When the MCB is operational, the contacts remain closed, allowing current to flow through the circuit.
Arc extinguishing chamber: This chamber contains insulating material that helps extinguish the arc formed when the main contacts separate during a fault condition.
Trip mechanism: The trip mechanism senses when the current exceeds the predefined threshold and activates the breaker, disconnecting the main contacts.
Auxiliary contacts: These contacts are used for signaling and interlocking purposes, providing additional safety features to the MCB.
