Residual current circuit-breakers (RCCBs) are components for implementing protective measure “Automatic disconnection of the power supply” as per VDE 0100 part 410 or corresponding international installation regulations. Series DFS 2 devices are compact two-pole residual current circuit-breakers for single-phase networks. In the standard design, they only take up two module-width units of space. In spite of the compact dimensions, a number of different tripping currents and characteristics are available at rated currents, depending on the design, up to 125 A. They also have large two-tier terminals for large conductor cross-sections, a practical multifunctional switch toggle and can be provided with pre-prepared labels using free-of-charge software. Switches for residual current type F are mains voltage-independent and record type A sinusoidal alternating and pulsating DC residual currents as well as residual currents with mixed frequencies that differ from 50 Hz. For example, these can arise when using single-phase frequency converters. RCCB of the DFS Audio series are optimised for protecting electric circuits that are connected to high-quality audio systems, such as record players, network streamers, amplifiers or sound systems for theatres and cinemas.# They have a low-impedance design to enable an unrestricted current flow and undisturbed sound quality.##DFS in the “Audio” design are ideal for protecting electric circuits with high-quality audiophile components, such as record players, CD players, network streamers, amplifiers, active loudspeakers or even sound systems for theatres, cinemas. Design optimisations, such as solid silver-plated connection terminals, solid and silver-plated internal current conductors

made from high-purity and low-oxygen copper, large main switching contacts with a high contact pressure and a special design of the summation current transformer, which minimises inductive parts in regular operation ensure an unrestricted current flow. This extremely low-impedance setup guarantees pure listening enjoyment thanks to the protective audiophile components.#
