Doepke circuit breaker with FI 4p, 125 A, 0.03 A, type B NK

Circuit breakers with error current protection (CBR) switch high currents, protect equipment, cables and lines from overcurrent and people from electric shock. DFL 8 are compact devices with integrated auxiliary switch and connection terminals for large line cross-sections. Type B switches are all-current sensitive at frequencies from 0 Hz (smooth DC) to 150 kHz. They are increased shock current and maternal. Switches with the NK characteristic offer the classic fire protection of 300 mA at frequencies up to 150 kHz. They are optimized for fire-prone operations. Switches of this variant have a fixed measurement error current of 30 mA for personal protection. They thus ensure the protection of the defects and fire as well as the additional protection (personal protection, protection in case of direct contact). 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: fixed measurement error current of 0.03 A, high tolerance to fluctuations in the auxiliary voltage of the type B, net and auxiliary voltage independent of the measurement voltage of the type A, four-pole, low-speed, low-speed, low-speed, high-speed, high-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-speed, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-current, low-which are not galvanically separated from the grid on the input side, the use for the protection of the error current in TNC networks is excluded.
