Doepke FI protection switch 4p, 80 A, 0.03 A, type B NK, 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 NK series of all-current sensitive error control switches offer the classic fire protection of 300 mA at frequencies from 0 to 150 kHz. They are optimized for fire-prone operations. 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: all-current sensitive to the frequency and mixed frequency of 0 Hz (smooth direct current) to 150 kHz, power-independent trigger for type A error flows, voltage-dependent detection of smooth DC current and AC current with frequencies not exceeding 50 / 60 Hz, full operation with network voltage of at least 50 V AC at any two active conductors, low power-output size for all rated currents, high short-circuit strength, two-sided double-deck terminals for large-cross-section and rail connections, switching display, display windows for the display of the high-speed control systems, for example: Photovoltaic and USB systems with trafolous inverters, fire-prone operations, 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.
