FATECH 60kA surge protector FV30B+C/4-150 for AC power system

Product catalog summary

Specifications:
The document outlines the specifications for the FV30B+C/4 series surge protective devices, which are designed for low-voltage power systems. The models include FV30B+C/4-150(S), FV30B+C/4-275(S), FV30B+C/4-320(S), FV30B+C/4-385(S), and FV30B+C/4-440(S). These devices are classified under IEC/EN/VDE Class I+II/B+C and are suitable for TT and TN network types. They operate in protection modes L1, L2, L3, N-PE with nominal voltages of 110/220V~ and 220/380V~.

Performance Parameters:
The rated voltage (UC) varies from 150V~ to 440V~ across models. The impulse current (Iimp) is 7kA, with a maximum discharge current (Imax) of 60kA and a nominal discharge current (In) of 30kA. The voltage protective level (Up) ranges from ≤0.9kV to ≤2.2kV, and the response time (tA) is ≤25ns. A recommended back-up fuse of 160A is suggested.

Physical and Environmental Characteristics:
The devices have an isolation resistance greater than 10 MΩ and support I/O connections with multi-core wire ranging from 4mm to 25mm. They are mounted on a 35mm symmetrical rail (EN50022/DIN46277-3) and operate within a temperature range of -40℃ to +80℃, humidity of 30% to 90%, and up to an altitude of 3000m. The degree of protection is IP20, and the housing material is UL94 V-0 rated.

Additional Features:
The devices include a mechanical disconnection indicator (green for OK, red for replace) and an optional remote control contact. The remote control contact supports AC signals up to 250Vmax and DC signals up to 60Vmax, with specific wire specifications.

Design and Functionality:
The FV30B+C/4 series consists of a base part and MOV pluggable protection modules, suitable for use in lightning protection zones at boundary 1-2. They feature metal oxide varistor components with high discharge capacity, low residual voltage, and quick response. The devices ensure reliable control through a Thermo Dynamic Control disconnector and provide fault indication via a red mark in the inspection window.
