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. Selective power control switches are used in systems with stacked distributions. In the event of an error, only the switch in which the error current is present is triggered. The selective RCCB offer fire and error protection (when touching indirectly), but not additional protection (direct touching, personal 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: response delay for selective design, high immunity against shock 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, triggered, power-mounted, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed, high-speed. Selective power protection switches protect the cables from the main distribution to the subdivisions, excluding the use in TNC networks and for the protection of systems where electronic equipment can cause smooth DC 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 +), notes: To ensure selectivity of the RCCB. The measurement error current of the selective RCCB shall be selected at least one step higher than that of the undelayed switch downstream.
