Circuit breakers are essential components of electrical systems such as power supplies, substations and switchboards. They are designed to perform the role of protecting individuals and equipment from over-currents, and to perform isolation functions. IEC 6-30398-2-V application field and working principle is related to a specifically designed circuit breaker called Moulded Case Circuit Breaker or MCCB.

MCCBs are used in places where circuit protection and isolation are required, such as industrial and commercial spaces. The IEC 6-30398-2-V specifications defines the application field and working principle of MCCBs, including the characteristics of the circuit breakers, the types, the international reference standards and safety rules.

MCCBs are mainly divided into two main categories: Curve A and Curve B. Curve A indicates the ability of the circuit breaker to interrupt high fault currents. Curve B, on the other hand, indicates the ability of the breaker to disconnect of short-circuited currents.

The core purpose of a MCCB is to prevent current from exceeding a certain the value. This is done through its thermal-magnetic operating principle. This principle combines the effects of electromagnetic force and the heat generated by the current.

When a current above the set threshold flows through the MCCB, the heat generated causes an increase in the temperature of the thermal element. This causes an increase in the contact force and disconnects the circuit. On the other hand, when set the current threshold is exceeded, an electromagnetic force acts on the moving core of the MCCB, causing the current to be interrupted.

The IEC 6-30398-2-V standard also specifies the requirements regarding safety. For example, the circuit breakers must have protective devices that can detect abnormal conditions and disconnect the circuit before the current threshold is exceeded. This prevents the circuit from overloading, which could cause fires or explosions. The requirements of IEC 6-30398-2-V must be fulfilled to ensure the safety and quality of the circuits.

The MCCB has numerous advantages. Its thermal-magnetic magnetism reduces the risk of damages due to high fault currents, while its mechanical construction ensures it can handle extremely high short-circuit conditions. It is also designed to handle many starts, dramatically reducing maintenance costs. The MCCBs can be operated manually, either locally or remotely, with the use of switches.

In conclusion, MCCBs are designed to provide protection and isolation in industrial and commercial spaces. The IEC 6-30398-2-V defines the application field and its working principle. The two main types of MCCBs are Curve A and Curve B, with their respective abilities to interrupt high-fault and short-circuit currents. The thermal-magnetic principle is used to limit the current to a certain level, preventing accidents and damages. Its advantages also include its potential to be operated remotely and its reliance on fewer starts. The requirements of IEC 6-30398-2-V must be met to guarantee the quality and safety of the circuit breaker.
