Description: Residual current circuit-breakers, two-pole, 40 A, 0,03 A, Type F, for audiophile applications, N arbitrary
Function: 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. The compact residual current circuit-breakers are available with a number of different types of residual currents and versions at rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. A practical multifunction switch toggle simplifies troubleshooting. They can be provided with pre-prepared labels using free-of-charge software. 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.
Properties: 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 conductors with standard design left, for two-terminal-pair devices type A/AC/F up to 125 A and type B/B+ up to 80 A; N-right available at no extra charge.
Installation: quick fastening to mounting rail, any installation position, supply from any direction
Applications: 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.
