Doepke 09166995 RCCB RCD (all types of current) 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. Standard type devices are designed for monitoring circuits with a rated voltage of 230, 400 V, V and a rated frequency of 50 Hz. Features: All-current sensitive for fault currents with frequencies and mixed frequencies from 0 Hz (smooth direct current) to 150 kHz; mains-voltage independent triggering in case of fault currents of type A; voltage-dependent detection of smooth direct-current fault and alternating fault currents with frequencies not equal to 50/60 Hz; full functionality with mains voltages from at least 50 V AC on two active conductors; small size for all rated current; high short-circuit resistance; double-sided double-level terminals for large cross-section and rail connection; switch position display; sight window for labeling labels; multi-function switch handle with three positions: "on", "off", "triggered"; connection C1 neutral position left; mounting type: rapid mounting on rail; mounting position random; preferably feed from above; application areas: Industrial and industrial installations with TN-S, TT and TN-C-S systems, in which power electronics equipment without galvanic isolation are used, such as frequency converters, switched-mode power supplies, high-frequency converters. Photovoltaic and UPS systems with transformerless inverters; facilities at risk of fire; notes: Suitable for use in 50-Hz AC power systems; 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.
