Doepke FI protection switch 4p, 40 A, 0.3 A, type A, KV, 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. Fault flow control switch in KV version (KV for short-term delays) are significantly more insensitive for short-term impulse-like shock and error-flow. They thus increase the plant availability. The additional protection (personal protection) is maintained. The short-term delayed switches can therefore be used without any problems instead of a standard switch. 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: high immunity to shock-flow and power-driven follow-on pulse, net and auxiliary voltage-independent trigger, sensitive to alternating and pulsating parallel-error flows (type A), low size for all face-to-face flows, high short-circuit strength, two-sided double-deck terminals for large cross-section and rail connection, switching display, display window for label labels, multi-function nebula with three positions: one, off, trigger, neutral-circuit position left, installation type: fast-fitting, power-to-drive position: Special purpose buildings and industrial plants with TNS, TTC and TNC networks in which conventional RCCBs cause unwanted trigger due to transient flow flows, such as: For example, plants with large line lengths behind the RCCB, lighting systems with many fluorescent lamps (> 20 pieces), computer and solar systems, excluding the use in TNC networks and for the protection of systems. 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 +).
