 ОбзорRCBOs are a combination of an RCCB and a miniature circuit breaker in a compact design for personnel, fire and line protection. For personnel and fire protection, the residual current part of the type A trips in the event of sinusoidal AC residual currents and pulsating DC residual currents. RCBOs with a rated residual current of maximum 30 mA are used for personnel, material and fire protection, as well as for protection against direct contact. RCBOs with a rated residual current of 10 mA are primarily used in areas that represent an increased risk for personnel and the outdoor installations of residential buildings. Devices with a rated residual current of maximum 300 mA are used as preventative fire protection in case of insulation faults. The MCB part of the RCBO protects lines against overload and short-circuits and is available in characteristics B and C. Since DIN VDE 0100-410 came into effect in June 2007, all socket outlet current circuits up to 20 A must now also be fitted with residual current protective devices with a rated residual current of max. 30 mA. This also applies to outdoor electrical circuits up to 32 A for the connection of portable equipment. In order to implement this protection, we recommend the national use of RCBOs with 30 mA. Assignment to each individual branch circuit, helps prevent the unwanted tripping of fault-free circuits induced by the accumulation of operation-related leakage currents or by transient current pulses during switching operations. Additional components of the 5SY miniature circuit breakers can be mounted at the side and carry out additional functions. For further details on additional components, please refer to the section "Miniature circuit breakers". Тех. данные
