We know that the role of 63 amp mcb circuit breakers is to protect electricity safety and personal safety. Circuit breakers are used in different systems. There are two main roles of electrical switches in photovoltaic systems:First, electrical isolation function, during installation and maintenance, cut off the electrical connection between photovoltaic modules, inverters, power distribution cabinets and power grids to provide a safe environment for operators. This action is actively realized by operators.The second is the safety protection function, when the electrical system occurs over current, over voltage, short circuit over temperature and leakage current, can automatically cut off the 63 amp mcb circuit, in order to protect the safety of the person and equipment, this action is automatic switch realization.
