Doepke FI protection switch 4p, 63 A, 0.03 A, type B + MI, 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 + error control switches are all-current sensitive. They protect against pulse and alternating error flows, error flows with mixing frequencies and smooth simultaneous error flows. They detect complete error flows of all frequencies up to 20 kHz at a maximum trigger threshold of 420 mA. The switches offer a high fire protection. 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. 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: 6 mA trigger threshold for smooth double-error flows, all-current sensitive to frequency and mixed frequency flows from 0 Hz (smooth direct current) to 20 kHz, fire protection according to VDE 0100-420, power-independent trigger for type A error flows, voltage-dependent detection of smooth double-error flows and intercurrent flows with frequencies of not more than 50 Hz, full operation with net voltage from at least 50 V AC, fire protection according to VDE 0100- 420, power-independent trigger for type A error flows, voltage-dependent detection of smooth double-error flows and intercurrent flows, full operation with power voltage from at least 50 Hz (50 V), at any two active conductors, low-size for all-to-scale, high-speed, high-speed, multi-speed control devices: For example, for temporary equipment with a pre-stored RCCB of unknown type. Due to the low DC trigger limit, the all-current-sensitive RCCB of the MI version may also be operated behind RCCB of type A or F, commercial and industrial, as well as mobile installations with TNS, TT and TNC-S systems, where power electronics are used without galvanic power separation, such as frequency converters, control power sets, high-frequency current converters. Photovoltaic and USB systems with trafolous inverters, fire-prone operations.
