DFS4 100-4 / 0.30-B +, Doepke FI protection switch 4p, 100 A, 0.3 A, type B +, N-li

Doepke FI protection switch 4p, 100 A, 0.3 A, type B +, 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. 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 20 kHz, fire protection as defined in VDE 0100-420, power-independent trigger for type A error flows, voltage-dependent detection of smooth DC and AC with frequencies of not more than 50 Hz, full operation with power voltage of at least 50 V AC on any two active conductors, low size for all rated currents, high short circuit strength, two-side double-deck terminals for large circuit and rail connection, switching devices for the control of the power-line system, for example, with a high-speed control system, with a high-speed control system, for the control of the assembly of the following: 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.
