Details

Residual current circuit-breakers, four-pole, 63 A, 0,03 A, Type B SK, 60 Hz/290 V, 500 V, N left, HD

Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. Type B switches are AC-DC sensitive at frequencies of 0 Hz (smooth residual currents) to 150 kHz. They have increased resistance to surge currents and lightning. 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 With an airtight, encapsulated tripping mechanism from a special alloy and the stainless steel latch, residual current circuit-breakers in HD design are protected, in particular from corrosion, corrosive gases, moisture and extreme temperature fluctuations.

High level of immunity against leakage and residual currents due to operational conditions from frequency 1 kHz and higher, AC/DC sensitive for residual currents with frequencies and mixed frequencies of 0 Hz (smooth direct current) up to 150 kHz, 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", Neutral conductor position left

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.
