FATECH surge arrester FV20C/1-100PVS for protection DC system
Product catalog summary
Specifications:
The document outlines the specifications for the FV20C/1-PV series of DC surge protective devices used in photovoltaic systems. These devices are classified under IEC/EN/VDE Class II/C and are designed for photovoltaic networks with a protection mode of +/- — PE. The nominal voltage ranges from 48V dc to 1000V dc, with a maximum continuous operating voltage (UCPV) ranging from 75V dc to 1060V dc. The devices can handle a maximum discharge current of 40kA and a nominal discharge current of 20kA, with a voltage protective level ranging from ≤0.6kV to ≤3.6kV. The response time is ≤25ns, and the recommended back-up fuse is 125A. The isolation resistance is greater than 10 MΩ, and the devices are mounted on a 35mm symmetrical rail.
Procedures and Installation:
The devices are designed for easy installation with I/O connections supporting multi-core wires ranging from 4mm to 25mm. They operate within a temperature range of -40℃ to +80℃, humidity levels of 30% to 90%, and altitudes up to 3000m. The degree of protection is IP20, and the housing material is UL94 V-0 rated. A mechanical indicator shows the device status, with green indicating OK and red indicating replacement is needed. Remote control contact is optional, with specific port definitions for AC and DC connections.
Norms and Recommendations:
The document recommends using a back-up fuse of 125A and specifies the isolation resistance and mounting requirements. It also highlights the optional remote signaling contact for control devices and the fault indication via a red mark in the inspection window.
Key Features:
The surge protective devices are equipped with metal oxide varistor components for high discharge capacity and reliable control through a Thermo Dynamic Control disconnector. They are designed for 1-pole, I-type configurations and provide optional remote signaling contact for enhanced control.
