A molded case circuit breaker, or MCCB, is a safety device used to protect an electrical circuit from overload or short circuits. It works by automatically cutting off the power supply when a fault or overcurrent situation arises, thus preventing any damage to the electrical system. MCCBs can be used in both low-voltage and high-voltage systems.
In addition to providing protection against faults, they also provide isolation of the circuit for maintenance. MCCBs are typically installed in the distribution panel and provide a visible indication to let users know when the power is off.
Molding Case:The molded case or frame is the cushion that keeps all parts of the circuit breaker in place. It is solidly built from ‘glass polyester’ or ‘thermoset composite resin that gives a great nonconducting strength despite its compressed size.
Terminals:The terminals serve as connectors between external conductors and molded cases. They should be connected properly to prevent unusual heat production.
Operating Apparatus:This is the switch that opens and closes the molded case. Its handle connects the pull of the device and manual push.
Arc Chamber:The Arc Extinguisher’s primary role is to curb and split the arc that can damage your circuit breaker. The action results in exterminating the current flow in the circuit breaker. Inside the arc chamber are contacts. Their role is to conduct and disrupt functions. Arc ‘Runners, on the other hand, function as new electrodes for the arc. Arc chutes, on the other hand, compress the arc in the middle of sidewall insulators.
On application, MCCBs are designed to handle high currents, especially on expensive equipment. You will often find MCCB used commonly used in industrial-levels of machinery such as the following:
Motors:MCCBs protect motors by having their settings modify the inrush current and give the delay it may need. When done correctly, the motors are protected from overloads without triggering the tripping mechanism.
Welding Machinery:Welding machines utilize high currents, which normal circuit breakers cannot handle. An MCCB can be used to protect welding machines by connecting the machine to its own circuit breaker.
Generators:It is widely known that generators produce high levels of amps and need costly gen-sets. To shield the linked circuits and generator from faults that may happen in the system, having an MCCB is essential as it can handle its high current ratings and protects your generators as needed.
Capacitor Banks:MCCB lessens the currents, which in turn, corrects the ‘power factor’ in commercial and industrial-level systems.
