Doepke 09175695 DFS4 125-2/0,10-B NK 2-pole 125/0,1A residual current circuit breaker all-current sensitive

Residual current circuit breakers (RCCB) switch off the power supply when dangerously high residual currents occur. They thus 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 division units wide. They are available with many different residual current types and versions with rated currents of up to 125 A. The large double-deck terminals can also accommodate large conductor cross-sections. The tripped position of the multi-function switch toggle makes troubleshooting easier. The free label software helps with labeling. Type B switches are universal current sensitive at frequencies from 0 Hz (smooth DC residual currents) to 150 kHz. They are resistant to increased surge currents and storms. The universal current sensitive residual current circuit breakers of the NK series offer the classic fire protection of 300 mA at frequencies from 0 to 150 kHz. They are optimized for fire-prone premises. Standard devices are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Properties: Universal current sensitive for fault currents with frequencies and mixed frequencies from 0 Hz (smooth direct current) to 150 kHz, tripping independent of the mains voltage for type A fault currents, voltage-dependent detection of smooth direct fault current and alternating fault currents with frequencies other than 50/60 Hz, fully functional 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 double-deck terminals for large conductor cross-sections and rail connection, switch position indicator, viewing window for labeling labels, multi-function switch toggle with three positions: on, off, tripped, connection C1 neutral conductor position on the right, mounting type: quick fastening on mounting rail, installation position as desired, feed-in 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 mains isolation, such as. B. Frequency converters, switching power supplies, high-frequency power converters. Photovoltaic and UPS systems with transformerless inverters, Fire-prone operating locations, Notes: suitable for use in 50 Hz AC networks, RCCB for other frequencies on request, Not intended for use in DC networks or on the output side of controlled electrical equipment such as frequency converters.
