Residual current operated circuit-breaker with integral overcurrent protection, three-pole+N, 10 A, 0,03 A, B-characteristic, Type B+, short-time delayed
Function:
RCBOs combine residual current and miniature circuit-breakers in a single device (RCBO). They protect people against residual currents and systems against short-circuit and overload. The DRCBO 4 have a rated switching capacity of 6 kA. They provide a labelling area in addition to the tripping indicator. Type B+ residual current circuit-breakers detect smooth DC residual currents and all other residual currents at frequencies up to 20,000 Hz. The operating voltage required for this is taken from the mains supply. Correct power supply is ensured when the voltage between the mains conductors is ≥ 50 V. Pulsating and AC residual currents are detected independent of the mains voltage. Switches with tripping characteristic B are the standard protection for lighting and socket circuits. Standard switches are designed for electric circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz.
Features:
AC/DC sensitive for residual currents with frequencies of 0 Hz (smooth direct current) up to 20,000 Hz, mains-voltage-independent tripping when type A residual currents occur, compact design for all rated currents, switch position indicator, separate indication of tripping cause, strain-relief clamps with a wide terminal cross-section range on both connection sides, neutral conductor right, labelling area
Mounting method:
quick fastening to mounting rail, any installation position, supply preferably from above
Applications:
commercial and industrial installations with TT, TN-S and TN-C-S systems, where power electronics equipment is used without galvanic isolation from the mains, e.g. frequency converters, switching power supplies, high-frequency converters, photovoltaic installations and UPS equipment with frequency converters without transformers, Type B+ and type B RCBOs with characteristic curve NK should be used where fire protection is legally required.
Hints:
suitable for use in 50 Hz AC networks, RCBOs are also available for other frequencies upon request, not designed for use in direct current networks or on the output side of controlled electrical equipment such as frequency converters
