OVR PV Type 2 Surge Protective Devices

OVR PV Type 2 SPDs for Photovoltaic applications help divert the lightning currents within an electrical system resulting from indirect lightning events. They have effective voltage protection ratings keeping damaging voltage peaks from exceeding the withstand voltages of the protected equipment.

 

OVR PV Type 2 SPDs are typically installed inside the string/combiner boxes or inside the PV Inverter. Additional PV SPDs may be required for optimal protection if cable lengths between SPDs are greater than 10 meters.

Benefits

Extended lifetime
Safety Reserve system with two varistors per line to extend protection lifetime

 

Easy replacement
Pluggable cartridge for easy replacement during maintenance

 

Faster wiring
OVR T2 series use the same terminal as Pro M compact devices to offer complete coordination and time-saving in wiring operation

 

Easy identification
Clear information on the front of the product indicating the technical characteristics of the OVR
