Doepke 09948124 RCBO RCD (all types of current)

RCBO combines earth leakage and circuit breaker in one device (FI-/LS-combination). They protect people from residual currents and systems against short-circuits and overload. DRCBO 4 have a rated breaking capacity of 6 kA. In addition to the activation display, they also offer a caption window. Type B switches are all-current sensitive for frequencies from 0 Hz (smooth DC fault currents) to 150 kHz. They are surge current and weatherproof. Switches with the characteristic SK stand for fault protection and a high system availability. They are characterized by lower sensitivity at higher frequencies. System-related false alarms are thus largely avoided. The characteristic SK is optimized for systems where no fire protection is required. Switches with the characteristic C are for circuits with a high activation or Peak currents optimized. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz. Properties: All current sensitive for fault currents with frequencies from 0 Hz (smooth direct current) to 150 kHz; mains voltage-independent triggering in case of fault currents of type A; small size for all rated currents; switch position display; separate display of the trigger reason; bracket terminals with wide clamping cross-section range on both connecting sides; neutral right; labeling window; mounting type: Rapid mounting on mounting rail; arbitrary; mounting position; Supply preferably from above; applications: commercial and industrial installations with TT, TN-S and TN-C-S systems, in which power electronics equipment without galvanic isolation are used, such as frequency converters, power supply units, high-frequency converters, photovoltaic or UPS systems with transformer-free inverters; RCBO 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 AC power systems; RCBO are also available on request for other frequencies; not intended for use in DC power systems or on the output side of controlled electrical equipment such as frequency converters.
