Doepke FI protection switch 4p, 40 A, 0.03 A, type A, Twin, 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. The Twin version allows the function test of the power control switch without switching off the circuit. In this version two complete RCCB are combined: If both devices are on, a switch can be triggered by the test button. The second FI takes over the power supply and the protection function. 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. Characteristics: functional test of the power control switch without a power interruption, standard power protection even during the test procedure, no costs due to plant standstill, high plant availability, high immunity to shock and power-driven follow-on pulse, net and auxiliary power-independent trigger, sensitive to alternating and pulsing DC-current (type A), low size for all measurement flows, high short circuit strength, two-sided double-deck terminals for large cross-section and rail connection, switching indicator, display of the position of the system, display of the type of the installation, of the type of the device: 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, systems with large line lengths behind the RCCB, lighting systems with many fluorescent lamps (> 20 pieces), computer and solar systems, the twin design allows the regular required function test without a power interruption, thus ideal for laboratory or IT areas, the use in TNC networks and for the protection of systems is excluded. in which electronic equipment can cause smooth parallel or error flows with frequencies of not more than 50 Hz, information: reactivation lock WES 2 mounted on the work side.
