Doepke FI protection switch 4p, 25 A, 0.03 A, type A, with NOx-off function, 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 A switches are pulse and AC sensitive. This function is power independent. For example, buttons for switching off in emergency situations can be connected to NAs (NA for NOT-OFF). An integrated LED displays the emergency solution by a button or wire break. The fault current control switch can only be switched on after the correction. Several RCCB can be connected in parallel. Characteristics: net and auxiliary voltage-independent trigger, sensitive to alternating and pulsing DC-current (type A) only 1 / 2 TE wider than the standard device, no additional power supply for the NOT-output circuit necessary, full separation characteristics, in case of a voltage failure, the NOT-output function does not lead to any trigger, low component size for all measuring currents, high short-circuit strength, two-sided double-deck terminals for large cross-section and rail connection, control display, display windows for marking labels, multi-function control systems, specially designed for the installation of the CCB-type: For example, in teaching rooms or in production facilities, the use in TNC networks and the protection of plants is excluded. in which electronic means of operation can cause smooth parallel or error flows with frequencies of not more than 50 Hz. There is no comprehensive protection here. For such applications we recommend our all-current-sensitive error control switches (type B or B +).
