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 switches are sensitive to all currents at frequencies from 0 Hz (smooth DC residual currents) to 150 kHz. They are resistant to increased surge currents and storms. Switches with the SK characteristic curve stand for fault protection and high system availability. They are characterized by a lower response sensitivity at higher frequencies. System-related false tripping is thus largely avoided. The SK characteristic curve is optimized for systems in which no fire protection is required. Switches with the B tripping characteristic are the standard protection for light and socket circuits. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz. Properties: universal current sensitive for fault currents with frequencies from 0 Hz (smooth direct current) to 150 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, type of installation: quick fastening on a 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 without galvanic mains isolation is used, such as frequency converters, switching power supplies, high-frequency converters, photovoltaic or UPS systems with transformerless inverters, RCBO with SK characteristic curve can be used there. where high leakage currents are to be expected and fire protection is not 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.
