Type F residual current circuit-breakers are sensitive to mixed frequencies. Our audio RCCB ensures undisturbed sound quality when operating high-end audio systems. Thanks to its low-impedance design, the audio RCCBs allow for unrestricted current flow – delivering a powerful and immersive listening experience.

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 , ideal for protecting high-quality audio components, optimised design for sound quality, e.g. silver-plated internal current conductors, silver-plated connection terminals etc, 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 or right

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

The Audio is primarily used in electric circuits with high-quality audiophile components, such as record players, CD players, network streamers, amplifiers, active loudspeakers or even sound systems for theatres or cinemas, Residual current type F ensures a high system availability due to its resistance to transient surge currents as well as the reliable detection of AC and pulsating residual currents with a rated frequency (50 Hz), even if other frequency components are present in the residual current, as may occur in modern audio devices with transformer or network parts.

Also available as a 60 Hz version.
