Residual current circuit breaker with integral overcurrent protection Investing in your future OPERATION PART FINANCED EfTHE EUROPEAN UNION European Regional Development Fund KZS 1M-FN is a residual current circuit breaker with integral overcurrent protection (RCBO), functionally dependent on line voltage. It comes in a single pole version that switches the phase pole while the neutral pole stays fixed. KZS 1M-FN is dependent on voltage and operates at voltages above 85V. KZS 1M-FN also has a sealing possibility. Technical data Rated short-circuit capacity Tripping characteristic Rated residual current Terminals line/load Build-in width Length of neutral conductor Operating temperature

Blue conductor with length of 600 mm is the neutral conductor on the line side. White conductor is connected to FE and is used for earthing the electronics.
