Doepke 09115820 RCCB for mixed frequency bands F

Ground fault circuit interrupter (RCCB) switch off the power supply in case of dangerously high fault currents. Thus, you protect persons, animals and plants. DFS 4 are two or four pole ground fault circuit breakers for single or three phase networks. In standard design, the compact devices are four division units narrow. They are available with many different fault current types and versions at rated currents up to 125 A. The large double level terminals can also accommodate large conductor cross-sections. The trip position of the multifunction toggle facilitates troubleshooting. The free label software helps with the labeling. Type F switches are mix frequency sensitive. They protect against power supply independent of pulse and AC fault currents as well as residual currents with mixed frequencies differing from 50 Hz. They are surge current and weatherproof. Standard type devices are designed for monitoring circuits with a rated voltage of 230, 400 V, V and a rated frequency of 50 Hz. Properties: Sensitive for alternating and pulsating DC fault currents of the mains frequency (type A) as well as alternating fault currents with mixed frequencies not equal to 50 Hz; high immunity against shock fault currents and mains voltage-driven following current pulses; small size for all rated currents; high short-circuit resistance; double-sided double-level terminals for large conductor cross-section and rail connection; switch position display; viewing window for label labels; multi-function switching toggle with three positions: "ON", "OFF", "triggered"; Connection C1 Neutral line position left; installation type: rapid mounting on mounting rail; mounting position arbitrary; infeed direction random; application areas: modern house installations with LED lighting systems as well as single-phase frequency converters; Ideal for systems in which RCCB of type A tend to trigger incorrect due to shock fault currents; Industrial and industrial installations with TN-S, TT and TN-C-S systems, in which power electronics equipment without galvanic isolation are used, such as switching power supplies, high-frequency converters, photovoltaic and UPS systems with transformerless inverters; the use in TN-C networks and for the protection of plants is excluded. Where electronic equipment can cause smooth DC fault currents. There is no comprehensive protection here. For such applications, we recommend our all-current-sensitive residual current circuit breakers (type B or B+); notes: Suitable for use in 50-Hz AC power supplies; not intended for use in DC power supplies and on the output side of controlled electrical equipment such as frequency converters.
