Residual current circuit-breakers, four-pole, 16 A, 0,03 A, Type F, N left, HD

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. 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. Devices in the standard design are intended for monitoring circuits with a rated voltage of 230 V, 400 V and a rated frequency of 50 Hz. 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.

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, 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 from any direction

Modern domestic installations with LED lighting systems and single-phase frequency converters, Ideal for systems where RCCBs Type A have a tendency towards faulty trips due to surge residual currents, Commercial and industrial installations with TN-S, TT- and TN-C-S systems, where power electronics equipment is used without galvanic isolation from the mains, e.g. switching power supplies, high-frequency converters, photovoltaic installations and UPS equipment with frequency converters without transformers, Not permitted for use in TN-C networks; not permitted for protecting systems in which electronic equipment could generate smooth DC currents. Comprehensive protection is not provided in this case. For these applications we recommend our AC/DC sensitive residual current circuit-breakers (Type B or B+).

suitable for use in 50 Hz AC networks, Not designed for use in direct current networks or on the output side of controlled electrical equipment such as frequency converters.
