In the realm of photovoltaic (PV) systems, Moulded Case Circuit Breakers (MCCB) play a pivotal role in ensuring the safe and efficient operation of these renewable energy systems. MCCBs are low-voltage electrical devices that provide protection against electrical overloads and short circuits, making them crucial components in PV installations.

    MCCBs are designed with a moulded case that provides both mechanical protection and insulation for the internal circuit breaker mechanism. This feature, combined with their compact size and high interrupting capacity, makes MCCBs ideal for use in PV systems, where space is often limited and high-performance requirements must be met.
