Type F residual current circuit-breakers are sensitive to mixed frequencies. RCCBs in the Hz design are intended for rated mains frequencies other than 50 Hz. The frequency range for tripping current detection remains unaffected by this. The HD design makes our RCCBs particularly resistant to harmful environmental influences and therefore suitable for harsh environments.

sensitive to AC residual currents and pulsating DC residual currents at the mains frequency (type A) as well as AC residual currents with multiple frequency components not equal to 50 Hz, high immunity against surge currents and mains-voltage-operated secondary current impulses , compact design for all rated currents, high short-circuit resistance, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "off" and "tripped", Neutral conductor position left

quick fastening to mounting rail, any installation position, supply from any direction
