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 B are all-current sensitive. You protect against pulse and AC fault currents, fault currents with mixed frequencies and smooth DC fault currents at frequencies up to 150 kHz. They are increased surge and storm-proof. Residual current circuit-breakers of series SK are available for fault-current protection and a high plant availability. They are characterised by a lower sensitivity at higher frequencies. The characteristic curve SK is optimized for systems in which no fire protection is required. 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. With an air tight sealed trigger in special alloy and the stainless steel switch lock are fault-current protective switch in HD-design especially against corrosion, harmful gases, moisture and strong temperature fluctuations. Features: - high immunity vis-à-vis operational deflection and residual currents at frequencies above 1 kHz; - meets the requirements of the building regulations VDE 0664-40 0664-10, VDE, ÖVE/ÖNORM E 8601 current sensitive for fault currents with frequencies and mixed frequencies from 0 Hz (smooth Dc current) up to 150 kHz; - electromagnetic compatibility to VDE 0839-6 0664-30 as well as VDE-2 (noise immunity for industrial applications) - independent of mains supply, triggering the residual currents of the type A; - voltage-dependent detection of smooth DC fault current and AC fault currents with frequencies? 50/60 Hz; - full functionality with mains voltages from at least 50 V AC at any two active conductors - 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"; - Neutral Position left, at no extra cost as a N right available. Installation type: quick mounting on rail fixing - any installation position feed preferably from the top applications: - Industrial and 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 Frequency converter, switching power supplies, high-frequency converter, photovoltaic and UPS systems with transformerless inverters. Notes: - suitable for use in 50-Hz-Wechselstromnetzen; - RCCB for other frequencies on request; - Not for use with DC power networks, as well as on the output side of controlled electrical equipment such as Frequency converters.
