Doepke FI protection switch 4p, 80 A, 0.1 A, type B SK, N-li

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. Standard-version devices are designed for the monitoring of circuits with a measurement voltage of 230 V, 400 V and a measuring frequency of 50 Hz. Characteristics: high immunity from operating flow and error flows at frequencies of 1 kHz and up to 1 kHz, all-current sensitive to error flows with frequencies and mixed frequencies of 0 Hz (smooth direct current) to 150 kHz, power-independent trigger for error flows of type A, voltage-dependent detection of smooth direct error current and intercurrent flows with frequencies of less than 50 / 60 Hz, full power-supply power of at least 50 V AC at any two active conductors, low component size for all measurement flows, high short-circuit strength, two-side double-stroke terminals for high-speed circuit and high-speed control systems, for example: Photovoltaic and USB systems with trafolous inverters, information: suitable for use in 50-Hz AC networks, 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.
