Doepke 09176979 RCCB RCD (all types of current) S/B 0.3 A

Ground fault circuit interrupter (RCCB) switch off the power supply in case of dangerously high fault currents. Thus, you protect persons, animals and plants. DFS 4 are two or four pole ground fault circuit breakers for single or three phase networks. In standard design, the compact devices are four division units narrow. They are available with many different fault current types and versions at rated currents up to 125 A. The large double level terminals can also accommodate large conductor cross-sections. The trip position of the multifunction toggle facilitates troubleshooting. The free label software helps with the labeling. Type B switches are all-current sensitive for frequencies from 0 Hz (smooth DC fault currents) to 150 kHz. They are surge current and weatherproof. The all current sensitive fault current circuit breaker of the NK series offer the classic fire protection of 300 mA at frequencies from 0 to 150 kHz. They are optimized for operation in fire-prone areas. Selective earth leakage circuit breakers are used in systems with staggered distribution panels. In the event of a fault, only the switch in which the fault current is present is triggered. The selective RCCB offer fire and error protection (in case of indirect contact) but not additional protection (direct contact, personal protection). Standard type devices are designed for monitoring circuits with a rated voltage of 230, 400 V, V and a rated frequency of 50 Hz. Properties: Selective to all instantaneous RCCB; all current sensitive for fault currents with frequencies and mixed frequencies from 0 Hz (smooth DC) to 150 kHz; mains voltage-independent triggering in case of fault currents of type A; voltage-dependent detection of smooth DC fault current and alternating fault currents with frequencies not equal to 50/60 Hz; Full functionality with line voltages from at least 50 V AC at any active conductors; small size for all rated currents; high short-circuit resistance; double-sided double-level terminals for large conductor cross-section and rail connection; switch position display; sight window for label labels; multi-function switch lever with three positions: "on", "off", "triggered"; C1 neutral position connector on left; installation: rapid mounting on mounting rail; mounting any mounting type; Supply preferably from above; applications: Main distribution in wide-ranging power supplies with TN-S, TT and TN-C-S systems, in which sub-distribution equipment of power electronics can be used or connected, such as frequency converters, switched-mode power supplies, high-frequency converters, UPS and photovoltaic systems. Selective earth leakage current circuit breakers protect the cables from the main distribution to the sub-distribution units in most cases; notes: Suitable for use in 50 Hz AC networks; RCCB for other frequencies on request; not intended for use in DC power systems and on the output side of controlled electrical equipment such as frequency converters; To ensure selectivity of RCCB. The rated fault current of the selective RCCB must be selected at least one step higher than that of the subsequent undelayed switch.
