Surge protectors for photovoltaic installation

Like any electrical installation, the equipment constituting a PV installation (inverters and PV panels) can be subjected to destructive electrical perturbance: transient overvoltages generated by lightning.

CITEL has designed a complete range of Type 1 and Type 2 surge protectors for PV applications that are compliant with the IEC 61643-31 (or EN 50539-11) test standard.

Type 1 PV surge protector
CITEL Type 1 SPDs for PV are designed to withstand up to 12.5 kA 10/350µs, incorporating CITEL's exclusive and patented 'VG techology'. CITEL offers two ranges for DIN rail mounting and one range for PCB mounting.

Type 2 PV surge protector
In most installations, the SPD will be necesary or obligatory an will be of Type 2. CITEL offers two ranges of Type 2 PV surge protectors with a pluggable module design et one range for PCB mounting.
