The photovoltaic pluggable surge arresters provide protection for equipment on photovoltaic system (connected & standalone), against transient over voltages that occur on the electrical network (mains).,Pluggable photovoltaic surge arresters are installed in sub-distribution boards using DIN rail. They are used for common mode protection.,Maintenance is made easier with pluggable surge arresters as replacement cartridges can be simply plugged-in without the need to isolate the circuit.
