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. Equipment of version V are designed for special voltages. Standard equipment is designed for the monitoring of circuits with a rated frequency of 50 Hz. Characteristics: high immunity from operating flow and error flows at frequencies of 1 kHz or more, all-current sensitive to error flows with frequencies and mixed frequencies of 0 Hz (smooth direct current) to 150 kHz, power-independent trigger for type A error flows, voltage-dependent detection of smooth direct error current and AC flows with frequencies of less than 50 / 60 Hz, full operation with power voltage of at least 50 V AC at any two active conductors, low size for all measurement flows, high short-circuit strength, two-side double-stroke terminals for high-speed circuit control systems, with a high-speed control and high-speed control control system: USB and photovoltaic systems. Selective power protection switches protect the cables from the main distribution to the subdivisions, information: suitable for use in 50-Hz AC networks, RCCB for other frequencies on request, not for use in DC networks and on the output side of controlled electrical equipment such as frequency converters.
