FATECH surge arrester FV20C/3+NPE-275S for 3phase ac spd protection
Product catalog summary
Specifications:
The document outlines the specifications for remote control contact in surge protective devices. It specifies the range of signal access for both AC and DC systems. For AC, the maximum voltage is 250V with a current of 0.5A, using single-core wire with a maximum diameter of 1.5mm. For DC, the maximum voltage is 60V with a current of 0.1A, using multi-core wire with a maximum diameter of 1.3mm. If the model number lacks an 'S', it does not include remote control contact functionality.

Components and Features:
The device consists of a base part and pluggable protection modules (MOV + GDT). It is designed for use in lightning protection zones at boundary 1-2. The core components are metal oxide varistor components with high discharge capacity, low residual voltage, and quick response. It includes a reliable control mechanism with a Thermo Dynamic Control disconnector and a remote signaling contact for control devices. Fault indication is provided via a red mark in the inspection window. The protection mode covers L1, L2, L3-N, N-PE.

Technical Parameters:
The test class is IEC/EN/VDE Class II/C, suitable for TT type networks. Nominal voltage is 110/220V~ to 220/380V~. The maximum discharge current is 40kA, with a nominal discharge current of 20kA. Voltage protective levels vary by model, with L-N ranging from ≤0.7kV to ≤2.0kV and N-PE consistently at ≤1.5kV. Response times are ≤25ns for L-N and ≤100ns for N-PE. A recommended back-up fuse is 125A, and isolation resistance is greater than 10 MΩ.
