Residual current circuit-breakers DFS 2/4 B

SAFELY EQUIPPED FOR ANY RESIDUAL CURRENT THE PERFECT TRIPPING RESPONSE THANKS TO VARIOUS CHARACTERISTIC CURVES The tripping frequency response for the DFS 2 B and DFS 4 B type SK circuit-breakers has a tripping threshold up to 2 A at high frequencies. If system-specific, high-frequency leakage currents are expected, the SK characteristic curve ensures the…
