Introduction
SP7 series surge protection devices are suitable for TT, IT, TN-S, TN-C, TN-CS and other power supply systems under AC 50/60Hz and 230/400V, and can discharge up to 100KA lightning overcurrent.
SP7 is installed in the equipotential connection between LPZOA and LPZ01 or LPZOB and LPZ1
Product Features
Adopt optimized structure design
Low residual voltage of impulse current and high endurance
Action response time is less than 25ns
The color of the windows shows the status of the protector ( It show RED when it is fault)
35mm Rail mounting, match most general installation requirements.
Application
For civil application
For industrial application
