What is PV MCB & How to work?
The use of a PV MCB is common in solar power systems that use DC power. In addition, this type of circuit breaker is also suitable for safeguarding primary circuits in photovoltaic battery packs and inverters.
The role of thermal protection in the DC MCB is to prevent excessive current flow that goes beyond the normal operating current level. It is designed to handle a slightly higher current load than what is considered normal. On the other hand, when there is a sudden surge of fault current, the magnetic protection component of the PV MCB comes into action. This magnetic protection mechanism is highly responsive and will instantly trip the PV MCB to protect the system.
