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 of the type A are pulse and alternating current and sensitive. This function is independent of mains voltage. Selective residual current circuit breakers are used in systems with tiered distributions are used. In the event of a fault only triggers the switch off, in the System section of the fault current is present. The selective RCCB offer fire and fault protection (in the case of indirect touch), but not the additional protection (direct contact, personal protection). 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: - on-delay for selective design; - high immunity to shock fault currents and mains voltage-driven sequence current pulses-power and auxiliary voltage-independent activation;-sensitive for change - and immediately pour pulsating errors (type A) - 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: - main distributions in wide-extended power supplies with TN-S, TT and TN-C-S-systems, e.g. for campsites, Marina, small garden colonies, shop parking spaces. Selective residual current circuit breakers protect the cable from the main distribution to the sub-distributions.; - excluded is the use in TN-C networks and for the protection of plants in which electronic equipment smooth DC residual currents or currents with frequencies is not equal to 50 Hz can cause. Here is a comprehensive protection. For such applications, we recommend our Allstrom-sensitiven residual current circuit breakers (Type B or B+). Notes: - in order to ensure that the selectivity of the RCCB the rated fault current of selective RCCB at least one level higher than that of the selected downstream undelayed switch.
