Surge protection for PV systems

[5140] The new Valvetrab MS Type 1+2 combined lightning current and surge arresters from Phoenix Contact have a 3+V circuit.

Thanks to their high short-circuit current rating and high-performance protective circuit, they deliver high system availability to PV systems.

Due to the voltage limiting varistors in the surge protective devices, you can use them in isolated DC voltage systems of up to 1,000 V DC. They secure each PV cable individually. The arresters supplement the existing VAL-MS product family with lightning current and surge protective devices with high continuous voltage and a high discharge capacity.

Alongside simple replacement when servicing is required, the coded plugs ensure a safe solution since it is impossible to plug them in incorrectly. In addition, the plugs offer an optical-mechanical status indicator for function monitoring and as required, a floating remote indication contact.
