Type 2 DC SPD, Imax 40kA, Class II PV Surge Protective Device

EKU5-T2-40 PV SPD is a DC surge protector specially designed for photovoltaic power supply systems. Max continuous operating voltage reach DC1500V.These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location is recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.

● Standard: IEC/EN 61643-31
● Surge Rating: Imax=40kA (8/20 µs)
● Voltage protection level (Up): <5,2kV
● IEC/EN Category: Class II / Type 2
● Max. continuous operating voltage (Ucpv): 600, 1000,1500V
● Housing: Pluggable Design

 

Porduct Overview

EKU5-T2-40PV Series is a pluggable multi-pole Type 2 PV Surge Protector (SPD) designed for use in photovoltaic solar applications. It is installed on the DC side to protect terminal devices in a PV system, such as solar panels and inverters, from the effects of lightning surge currents.
