The power supply (RCCB) switches off when dangerous high error flows occur. They thus protect persons, animals and plants. DFS 4 is a two or four-pole power control switch for one or three-phase networks. In standard design, the compact devices are four units narrow. They are available with many different types of error current and versions for measuring currents up to 125 A. The large double-deck clamps can also record large circuit cross sections. The triggering of the multi-function switch button facilitates the troubleshooting. The free label software helps with the labelling. Type B switches are all-current sensitive at frequencies from 0 Hz (smooth DC) to 150 kHz. They are increased shock current and maternal. The SK series of fault current protection switches are for fault current protection and high plant availability. They are characterised by a lower response sensitivity at higher frequencies. The SK characteristic is optimized for plants where no fire protection is required. For example, buttons for switching off in emergency situations can be connected to NAs (NA for NOT-OFF). An integrated LED displays the emergency solution by a button or wire break. The fault current control switch can only be switched on after correction. Several RCCB can be connected in parallel. Characteristics: high immunity from operating flow and error flows at frequencies from 1 kHz, all-current sensitive to error flows with frequencies and mixed frequencies from 0 Hz (smooth direct current) to 150 kHz, power-independent trigger at type A error flows, voltage-dependent detection of smooth direct error current and error flows with frequencies from less than 50 / 60 Hz, full operation with network voltage from at least 50 V AC on two any active conductors, with NOT-output function for triggering or In the case of a voltage failure, the NOT output function does not lead to any trigger, low size for all measuring currents, high short circuit strength, double-deck terminals for large cross-section and rail connection, switching display, display windows for label labels, multi-function nebula with three positions: as For example, in teaching rooms or in production facilities, information: suitable for use in 50-Hz AC, RCCB for other frequencies on request, not for use in direct current networks and on the starting side of controlled electrical equipment such as frequency converters.
