Doepke 09949324 DRCBO 4 C16/0,03/1N-B+ FI-/LS-combination 1p+N 16A content_copy

RCBOs combine residual current and circuit breakers in one device (FI/LS combination). They protect people from residual currents and systems from short circuits and overloads. DRCBO 4 have a rated switching capacity of 6 kA. In addition to the tripped indicator, they also have a labeling window. Type B+ residual current circuit breakers detect smooth DC residual currents and all other residual currents at frequencies up to 20 kHz. The operating voltage required for this is taken from the mains voltage. Correct voltage supply is guaranteed if the voltage between the mains conductors is >= 50 V. Pulse and alternating residual currents are detected independently of the mains voltage. Switches with tripping characteristic C are optimized for circuits with high inrush or peak currents. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz. Properties: universally sensitive for fault currents with frequencies from 0 Hz (smooth direct current) to 20 kHz, tripping independent of the mains voltage for fault currents of type A, small size for all rated currents, switch position indicator, separate display of the reason for tripping, clamping yoke terminals with a wide clamping cross-section range on both connection sides, neutral conductor on the right, labeling window, mounting type: quick fastening on mounting rail, installation position as desired, feed preferably from above, areas of application: commercial and industrial installations with TT, TN-S and TN-CS systems in which power electronics equipment is used without galvanic mains isolation, such as frequency converters, switched-mode power supplies, high-frequency power converters, photovoltaic or UPS systems with transformerless inverters, RCBO of type B+ and type B with NK characteristics are to be used there. where fire protection is required, Notes: suitable for use in 50 Hz alternating current networks, RCBOs are also available for other frequencies on request, not intended for use in direct current networks or on the output side of controlled electrical equipment such as frequency converters.
