RCBOs combine residual current protection and overcurrent protection in a single device. This makes them ideal for use in distribution boards where space is limited. The rated breaking capacity of the DRCBO 4 series is 6 kA. Type B circuit-breakers are AC-DC sensitive. The SK characteristic limits the risk of unwanted tripping providing maximum system availability, for frequencies ranging from 0 to 150 kHz. With low tripping sensitivity at higher frequencies, our SK circuit-breakers are perfectly suited for use in facilities where preventive fire protection measures are provided by additional means. With tripping characteristic C, these circuit-breakers ensure reliable protection for your circuits with loads that generate higher inrush peaks. Standard circuit-breakers are designed for circuits with 230 V or 400 V at 50 Hz.

AC/DC sensitive for residual currents with frequencies of 0 Hz (smooth direct current) up to 150 kHz, 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

quick fastening to mounting rail, any installation position, supply preferably from above

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.

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
