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. Error current circuit breakers of the SK series stand for fault current protection and a high plant availability. They are characterized by lower sensitivity at higher frequencies. The characteristic SK is optimized for systems where no fire protection is required. 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: High immunity to operational leakage and fault currents at frequencies above 1 kHz; 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 on 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 on right; mounting position: rapid mounting on mounting rail; mounting any mounting; Supply preferably from above; applications: Industrial and industrial installations with TN-S, TT and TN-C-S systems, in which power electronics equipment is used without galvanic isolation from the mains, such as frequency converters, switching power supplies, high-frequency converters. Photovoltaic and UPS systems with transformerless inverters; 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.
