Doepke FI protection switch 4p, 63 A, 0.03 A, type B SK MI, N-li, HD

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. Fault-control switch in MI version (mobile installations) can be easily switched RCCB of type A or unknown. They trigger > = 6 mA in the case of smooth simultaneous error flows and thus secure the protection function of the pre-current control switch. With an air-tight, unencapsulated trigger in special alloy and the stainless steel switch lock, error-flow switch in HD- version are especially protected against corrosion, harmful gases, moisture and strong temperature fluctuations. 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 alternating current with frequencies of less than 50 / 60 Hz, full operation with power voltage of at least 50 V AC on two active ladders, low size for all measurement flows, high short-circuit strength, two-side double-stroke clamps for large circuit boards, for the use of a single-line connection, with a single-line connection, with a single-line connection, with a single-line connection: For example, for temporary equipment with a pre-stored RCCB of unknown type. Due to the low emission limit of DC, the all-current-sensitive RCCB of the MI version may also be operated behind RCCB of type A or F, commercial and industrial installations with TNS, TTS and TNC-S systems where power electronics are used without galvanic power separation, such as frequency inverters, switching power sets, high-frequency generators. 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.
