Type F-SI Residual Current Devices

Type F-SI Super-immunized Residual Current Devices: the solution to nuisance tripping caused by modern electronics, LEDs, frequency inverters, and inverter appliances. They filter high-frequency leakage up to 1 kHz, something a Type A or AC cannot do. All Bogas Electronics models are approved according to IEC 61008 with CE certification and a 2-year warranty.
