Long Description

Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 4 are two-terminal or two-terminal pair residual current circuit-breakers for single- or three-phase networks. In the standard design, the compact devices are just four module widths wide. They are available with many different residual current types and variants for rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. The trip position of the multi-function toggle switch simplifies fault-finding. The free label software helps in the labelling process. Type B switches are AC-DC sensitive at frequencies of 0 Hz (smooth residual currents) to 150 kHz. They have increased resistance to surge currents and lightning. For residual current circuit-breakers with characteristic curve NK, the tripping current frequency response runs below human tolerance levels for shock currents with different frequencies. For RCCBs with a rated residual current of 30 mA, extensive personal safety is achieved even with residual currents above the rated frequency. With an upper tripping threshold of 300 mA at frequencies up to 150 kHz, significantly more sensitive and wider-reaching protection from earth leakage currents is provided compared to characteristics B SK and B+. As a result, extensive fire protection is also possible even with electronic equipment with high clock frequencies. The wide scope of protection thanks to the NK characteristic requires the monitored system to be set up with low leakage currents. Push-buttons for disconnection in emergency situations can be connected to residual current circuit breakers in the NA design (NA for emergency shut-off). An integrated LED indicates the emergency tripping by a push-button or wire break. The residual current circuit breaker can be reactivated once the fault has been rectified. Several RCCBs can be connected in parallel. Properties: AC/DC sensitive for residual currents with frequencies and mixed frequencies of 0 Hz (smooth direct current) up to 150 kHz; high availability even of voltage-independent detection of smooth DC residual current and AC residual current with frequencies not equal to 50/60 Hz thanks to full functional compatibility with mains voltages from at least 50 V AC on any two active conductors; mains-voltage-independent tripping when type A residual currents occur; With emergency shut-off function for tripping or disconnection by means of control elements; Monitoring of emergency shut-off function for wire breakage and signalling by LED; In the event of a power failure, the emergency shut-off function does not trip; compact design for all rated currents; high short-circuit resistance; double-sided two-tier terminals for large conductor cross-section and busbar; switch position indicator; viewing window for labels; multifunction switch toggle with three positions: "on", "off" and "tripped"; Connector C1 Neutral conductor position left; Mounting: quick fastening to mounting rail; any installation position; supply from top; Application areas: Commercial and industrial installations with TT, TN-S and TN-C-S systems, where power electronics equipment is used without galvanic isolation from the mains, e.g. frequency converters, switching power supplies, high-frequency converters. photovoltaic installations and UPS equipment with frequency converters without transformers; Facilities at risk of fire; Hints: suitable for use in 50 Hz AC networks; RCCBs for other frequencies available upon request; Not designed for use in direct current networks or on the output side of controlled electrical equipment such as frequency converters.
