Differential residual current circuit breaker
max. 32 A, 30 mA
SIEMENS Low-Voltage Power Distribution
RCBOs 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.
