Introduction
In the realm of renewable energy, photovoltaic (PV) systems have emerged as a popular choice for harnessing the power of the sun. These systems convert sunlight into electricity, providing a clean and sustainable energy source. However, to ensure the smooth and safe operation of these PV systems, efficient protection mechanisms are crucial. Moulded case circuit breakers (MCCB) play a pivotal role in PV systems, providing vital protection against overloads and short circuits.
What are Moulded Case Circuit Breakers (MCCB)? MCCBs are electrical protection devices designed to protect electrical circuits from damage caused by excessive current or short circuits. These breakers are housed in a moulded case, which gives them their name. MCCBs are widely used in low-voltage distribution systems, offering a balance between cost-effectiveness and performance. Role of MCCBs in PV Systems In PV systems, MCCBs play a crucial role in safeguarding the system components, such as photovoltaic modules, inverters, and batteries, from harmful electrical faults. PV systems are subject to a range of conditions, including varying weather patterns and the inherent intermittency of solar radiation. These factors can lead to fluctuations in the current generated by the PV modules, potentially causing overloads or short circuits.
