FATECH surge protector FV20C/2+NPE-xxx PVS for solar photovoltaic system

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. A recommended back-up fuse of 125A is suggested.

Physical and Environmental Specifications:
The device features a mechanical disconnection indicator and optional remote control contact. It operates within a temperature range of -40℃ to +80℃, humidity of 30% to 90%, and up to an altitude of 3000m. It has an IP20 protection degree and is made from UL94 V-0 housing material.

Additional Features:
The device includes a reliable control mechanism with a Thermo Dynamic Control disconnector and optional remote signaling contact. Faults are indicated via a red mark in the inspection window. It is a 3-pole, Y-type device.

Installation:
The device is mounted on a 35mm symmetrical rail (EN50022/DIN46277-3) and supports multi-core wire connections ranging from 4mm to 25mm.
