Doepke 09124889 RCCB B+

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 B+ ground fault circuit breakers are all current sensitive. They protect against pulse and alternating error currents, error currents with mixed frequencies and smooth direct fault currents. It detects error currents of all frequencies up to 20 kHz without any gaps with a maximum trigger threshold of 420 mA. The switches thus offer an enhanced fire protection. MI-type fault circuit breakers (mobile installations) can be connected downstream without any problem or unknown. They trigger in case of smooth direct currents >= 6 mA and thus secure the protection function of upstream current-operated ground fault circuit interrupter. Standard type devices are designed for monitoring circuits with a rated voltage of 230, 400 V, V and a rated frequency of 50 Hz. Features: Trigger threshold of 6 mA with smooth DC fault currents; all current sensitive for fault currents with frequencies and mixed frequencies from 0 Hz (smooth DC) to 20 kHz; fire protection according to VDE 0100-420; mains voltage-independent triggering with fault currents of type A; voltage-dependent detection of smooth DC fault currents and alternating fault currents with frequencies not equal to 50 Hz; Full functionality with line voltages from at least 50 V AC at any active conductors; 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; sight window for label labels; multi-function switch lever with three positions: "on", "off", "triggered"; C1 neutral position connector on left; installation: rapid mounting on mounting rail; mounting any mounting type; Preferably feed from above; application areas: Ideal for mobile use in power distributors e.g. for loan units, in which previously unknown type RCCB are present. Due to the low DC tripping limit, the MI all-current sensitive RCCB can also be operated behind type A or F RCCB; commercial and industrial as well as mobile installations with TN-S, TT and TN-C-S systems in which power electronics equipment is used without galvanic isolation from the mains, such as frequency converters, switched-mode power supplies, high-frequency converters. Photovoltaic and UPS systems with transformerless inverters; facilities at risk of fire.
