FATECH surge arrester FV20C/2+NPE-1000PV for PV Solar system protection

Product catalog summary
Specifications:
The document outlines the specifications for a DC surge protective device used in photovoltaic systems. It includes details on remote control contact, signal access range, and recommended wire specifications for both AC and DC systems. For AC, the maximum voltage is 250V with a current of 0.5A, using single-core wire up to 1.5mm. For DC, the maximum voltage is 60V with a current of 0.1A, using multi-core wire up to 1.3mm.

Model Information:
Models include FV20C/2+NPE-500PV(S), 600PV(S), 800PV(S), and 1000PV(S). If the model number lacks an 'S', it does not have a remote control contact function.

Test Class and Network Type:
The device complies with IEC/EN/VDE Class II/C standards and is designed for photovoltaic systems. It supports various protection modes and nominal voltages ranging from 500V to 1000V DC.

Performance Parameters:
The maximum discharge current is 40kA, with a nominal discharge current of 20kA. The voltage protective level varies from ≤2.0kV to ≤3.6kV, and the response time is ≤25ns. The recommended back-up fuse is 125A, and the isolation resistance is greater than 10 MΩ.

Installation and Operation:
The device is mounted on a 35mm symmetrical rail (EN50022/DIN46277-3) and operates within a temperature range of -40℃ to +80℃, humidity of 30% to 90%, and altitude up to 3000m. It has an IP20 protection degree and is made from UL94 V-0 housing material.

Additional Features:
The device includes a mechanical disconnection indicator (green for OK, red for replace) and an optional remote control contact. It features a reliable control system with a Thermo Dynamic Control disconnector and fault indication via a red mark in the inspection window. The device is a 3-pole, Y-type configuration.
