Doepke 09134820 DFS4 040-4/0,03-F RCCB Quick response -F- 4-pin 40 A 0.03 A 400 V

Residual current circuit breaker (RCCB) Switch the power supply whenever dangerously high fault currents. You protect people, animals and plants. DFS 4 are two- or four-pole residual current protective switch for single-phase or three-phase systems. In the standard version, the compact devices four division units narrow. They are equipped with many different fault current types and versions with rated currents up to 125 A available. The large Double level terminals can also be large conductor cross-section. The triggered position of the multi-function knob simplifies troubleshooting. The free label software helps with the label. Switch type F are mixed frequency and sensitive. They protect mains voltage independent before pulse and AC residual currents and residual currents with mixed frequencies. By way of derogation from 50 Hz. They are increased surge and storm-proof. Devices are in the standard version for the monitoring of circuits with a rated voltage of 230V/400V and a rated frequency of 50 Hz. Features: - sensitive for AC and pulsating DC fault currents of the network frequency (type A) as well as AC fault currents with mixed frequencies? 50 Hz - high immunity to shock fault currents and mains voltage-driven sequence current pulses - small size for all rated currents; - high short-circuit strength; - double-sided double terminals for large conductor cross-section and busbar connection; - switching position display; - a viewing window for labels; multi-function knob with three positions: "on", "off", "tripped"; - even in the design of "HD" available-neutral position left, at no extra cost as a N right available. Installation type: quick mounting on rail fixing - any installation position feed-in direction applications: - modern house installations with LED lighting systems, as well as single-phase frequency converters.; - Ideal for installations in which type A RCCB fault currents may lead to false alarms due to shock tilt.; - commercial and industrial installations with TN-S, TT and TN-C-S-systems where resources of power electronics without galvanic isolation from the mains, such as Switched-mode power supplies, high-frequency converter, photovoltaic and UPS systems with transformerless inverters.; - excluded is the use in TN-C networks and for the protection of plants in which electronic equipment can cause smooth DC fault currents. Here is a comprehensive protection. For such applications, we recommend our current-sensitive residual current protective switch (Type B or B+). Notes: - suitable for use in 50-Hz-Wechselstromnetzen; - Not for use with DC power networks, as well as on the output side of controlled electrical equipment such as Frequency converters.
