Doepke FI protection switch 4p, 125 A, 0.3 A, type B SK, sel, 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. Selective power control switches are used in systems with stacked distributions. In the event of an error, only the switch in which the error current is present is triggered. The selective RCCB offer fire and error protection (when touching indirectly), but not additional protection (direct touching, personal protection). 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: selectively to all uninterrupted RCCB, for systems with high transmission flows in the frequency range > 1 kHz, large insensitivity to transient transmission and error flows due to high impact strength, high immunity to operating transmission and error flows at frequencies of 1 kHz, all power-sensitive to error-flows with frequencies and mixing frequencies of 0 Hz, high-speed (smooth direct current) to 150 kHz, power-independent power-output for type A, voltage-dependent control of smooth current and variable-current currents at frequencies of at least 50 TV, high-speed, high-speed, high-speed, high-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, high-speed, high-speed, high-speed, high-speed, low-speed, high-speed, high-speed, high-speed, high-speed, high Selective power-protection switches protect the cables from the main distribution to the subdivisions, systems with a stacked distribution, 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: For example, frequency inverters are designed to ensure selectivity of the RCCB. The measurement error current of the selective RCCB shall be selected at least one step higher than that of the undelayed switch downstream.
