Residual current circuit-breakers, four-pole, 63 A, 0,03 A, Type B SK, 60 Hz/127 V, 220 V, N left

Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 4 are two-terminal or two-terminal pair residual current circuit-breakers for single- or three-phase networks. In the standard design, the compact devices are just four 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 B switches are AC-DC sensitive. They protect against pulsating and AC residual currents, residual currents with mixed frequencies and smooth DC residual currents at frequencies up to 150 kHz. They have increased resistance to surge currents and bad weather conditions. For residual current circuit-breakers with characteristic curve SK, the frequency response of the tripping current is designed so that residual currents with high frequencies, such as in the clock frequency range for frequency converters, as opposed to the rated frequency are detected with significantly reduced sensitivity. Undesired trips caused by leakage currents can therefore be widely avoided. However, fire protection depending on the rated residual current of the switch (0.03 A, 0.1 A or 0.3 A) is only provided for residual currents with frequencies up to 1 kHz, 300 Hz or 100 Hz, while the devices with tripping current frequency response B+ or NK offer protection over the entire tripping frequency range up to 20 kHz or 150 kHz, respectively. Residual current circuit-breakers 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. Rated voltage ≠ 230 V/400 V

high immunity against transient leakage and residual currents thanks to slow tripping response, meets the requirements of design regulations VDE 0664-10, VDE 0664-40, ÖVE/ÖNORM E 8601 , AC/DC sensitive for residual currents with frequencies and mixed frequencies of 0 Hz (smooth direct current) up to 150 kHz, electromagnetic compatibility in accordance with VDE 0664-30 and VDE 0839-6-2 (interference resistance for industrial applications), high availability even of voltage-independent detection of smooth DC residual current and AC residual current with frequencies not equal to 50/60 Hz thanks to full functional compatibility with mains voltages from at least 50 V AC on any two active conductors, mains-voltage-independent tripping when type A residual currents occur , 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", also available in the "HD" design, 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.

quick fastening to mounting rail, any installation position, supply preferably from above

Commercial and industrial installations with TT, TN-S and TN-C-S systems, where power electronics equipment is used without galvanic isolation from the mains, e.g. frequency converters, switching power supplies, high-frequency converters, photovoltaic installations and UPS equipment with frequency converters without transformers.

suitable for use in 60 Hz AC networks, Not designed for use in direct current networks or on the output side of controlled electrical equipment such as frequency converters.
