Doepke 09147905 RCCB A

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 A switches are pulse- and AC-sensitive. This function is independent of mains voltage. Selective earth leakage circuit breakers are used in systems with staggered distribution panels. In the event of a fault, only the switch in which the fault current is present is triggered. The selective RCCB offer fire and error protection (in case of indirect contact) but not additional protection (direct contact, personal protection). 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: On-delay for selective design; high immunity to shock fault currents and line voltage-driven follow-up current pulses; tripping independent of mains and auxiliary voltage; sensitive for alternating and pulsating DC fault currents (type A) small size for all rated currents; high short-circuit resistance; double-sided double-level terminals for large conductor cross-section and rail connection; switching position display; inspection window for label labels; multi-function switching toggle with three positions: "On", "off", "triggered"; Connection C1 Neutral conductor position left; mounting type: quick mounting on mounting rail; mounting position random; feeding direction any; application areas: main distribution in widely extended power supplies with TN-S, TT and TN-C-S systems, e.g. for camping sites, marinas, allotment colonies, exhibition grounds. Selective ground fault circuit breakers protect the cables from the main distribution to the sub-distribution units; the use in TN-C networks is excluded and for the protection of systems in which electronic equipment can cause smooth direct fault currents or fault currents with frequencies not equal to 50 Hz. There is no comprehensive protection here. For such applications, we recommend our all current sensitive circuit breakers (type B or B+); Notes: To ensure selectivity of RCCB. The rated fault current of the selective RCCB must be selected at least one step higher than that of the subsequent undelayed switch.
