09134046, Residual current circuit-breakers, two-pole, 40 A, 0,03 A, Type F, for audiophile applications, N left or right • sensitive to mixed frequencies, mains-voltage-independent • for audiophile applications • higher system availability: short-time delayed • silver-plated connection terminals • minimal power dissipation at each pole • VDE certified Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 2 are two-terminal residual current circuit-breakers for single-phase networks. In the standard design, the compact devices are just two module widths wide. They are available with many different residual current types and variants for rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. The trip position of the multi-function toggle switch simplifies fault-finding. The free label software helps in the labelling process. Type F switches are mixed frequency sensitive. They protect against pulsating and AC residual currents as well as residual currents with mixed frequencies that differ from 50 Hz independent of the mains voltage. 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.
