| Öğe açıklaması | DOEPKE residual current circuit-breakers 2-POLE, 25 A, 0.3 A, type b SK, n right, HD / residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. Series DFS 4 devices are compact two or four-pole residual current circuit-breakers. In the standard design, they only take up four module width units of space. Although DFS 4 devices for AC and pulsating DC residual currents are actually designed for three-phase networks, they CAN also be used in single-phase networks. However, in addition to these, special variants are also available for single or three-phase operation in the form of the AC/DC sensitive designs (type b, type b+). In spite of the compact dimensions, a number of different tripping currents and characteristics are available at rated currents, depending on the design, up to 125 A. All devices are available in the "HD" design, w |
