Earth leakage circuit breaker - Residual current breaker 4-p DFS4 040-4/0,10-B NK – Doepke – 09135995 – 4014712139411: FI switch DFS4 040-4/0.10-B NK number of poles 4, rated voltage 400V, rated current 40A, rated residual current 100mA, rated insulation voltage Ui 400V, rated impulse withstand voltage Uimp 4kV, mounting type DIN rail, residual current type B, short-time delayed type, short-circuit strength (Icw ) 10kA, surge current resistance 3kA, frequency 50 Hz, additional equipment possible, protection class (IP) IP20, width in pitch units 4, installation depth 69mm, ambient temperature during operation -25... 40°C, degree of pollution 2, connectable conductor cross-section multi-wire 1.5. .. 50mm², connectable conductor cross-section, solid 1.5... 50mm², residual current circuit breakers (RCCB) switch off the power supply if dangerously high residual currents occur. In this way, you protect people, animals and systems. DFS 4 are two- or four-pole residual current circuit breakers for single- or three-phase networks. In the standard version, the compact devices are four modules wide. They are available with many different residual current types and designs with rated currents up to 125 A. The large double-decker terminals can also accommodate large conductor cross-sections. The triggered position of the multifunction switch toggle makes troubleshooting easier. The free label software helps with labeling. Type B switches are AC/DC sensitive. They protect against pulse and alternating residual currents, residual currents with mixed frequencies and smooth direct residual currents at frequencies up to 150 kHz. They are more resistant to surge currents and thunderstorms. The all-current sensitive residual current circuit breakers from the NK series offer classic fire protection of 300 mA at frequencies from 0 to 150 kHz. They are optimized for fire-prone premises. Standard version devices are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Properties: meets the requirements of the building regulations VDE 0664-10, VDE 0664-40, VDE 0664-400, ÖVE/ÖNORM E 8601, all-current sensitive for residual currents with frequencies and mixed frequencies from 0 Hz (smooth direct current) to 150 kHz, electromagnetic compatibility according to VDE 0664-30 and VDE 0839-6-2 (interference immunity for industrial applications) mains voltage-independent triggering for type A residual currents, voltage-dependent detection of smooth direct residual currents and alternating residual currents with frequencies other than 50/60 Hz, full functionality with mains voltages from at least 50 V AC on any two active conductors, small size for all rated currents, high short-circuit strength, double-sided terminal blocks for large conductor cross-sections and rail connections, switching position indicator, viewing window for labels, multifunctional switch toggle with three positions: ''on'', ''off'', ''triggered'', too Available in the ''HD'' version, connection C1 neutral conductor position on the left, also available as N on the right at no extra charge. Mounting type: Quick fastening on mounting rail, installation position in any position, feed preferably from above, areas of application: Commercial and industrial installations with TN-S TT and TN-CS systems in which power electronics equipment is used without galvanic network isolation, such as: E.g. frequency converters, switching power supplies, high-frequency power converters. Photovoltaic and UPS systems with transformerless inverters. Fire-hazardous operating sites, Notes: suitable for use in 50 Hz AC networks, RCCB for other frequencies on request, Not for use in DC networks or on the output side of controlled electrical equipment such as. B. frequency converters.
