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. Equipment of version V are designed for special voltages. Standard equipment is designed for the monitoring of circuits with a rated frequency of 50 Hz. Characteristics: net and auxiliary-independent trigger, sensitive to alternating and pulsating parallel-error flows (type A), low size for all measuring flows, high short-circuit strength, two-sided double-deck terminals for large cross-section and rail connection, switching display, display window for labels, multi-function nebula with three positions: one, off, triggered, neutral-circuit position left, type of assembly: fast-fitting on the carrier rail, installation position, installation position of any kind, feed-in-of-line, and-of-line systems: In IT networks, fault-flow control switches of this series can be provided for shutdown in the event of a second error, the use in TNC networks and for the protection of equipment 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 +).
