Product information "Surge arrester type 1+2+3 with integrated backup fuse, 275/25 3+1 RC, leakage current-free, TN-S & TT"
o Phase-GDT voltage switching technology
o Integrated backup fuse
o Leakage current-free product for installation in the pre-metering area
o Shorter connection cables - low protection level
o Less space required, lower costs, less wiring and less complexity
o Reliable disconnection device
o Visualisation of the device status, also possible remotely
The GSMF series from RETI is based on PGDT (Phase Gas Discharge Tube) technology and includes integrated overcurrent protection. The products ensure safe disconnection in the event of overheating or residual currents in networks from 300 A up to 100,000 A. In networks with high prospective currents, SPDs with integrated fuses offer improved protection against overcurrent due to the coordinated tripping characteristics of the thermal cut-off device and the integrated fuse.
