Differential residual current circuit breaker 5SV1

with overcurrent protectionlow-voltageoverload

RCBOs (Residual current operated circuit breakers with overcurrent protection) combine residual current detection and overcurrent protection in a single device. The 5SV1 RCBOs for the first time combine residual current and overload protection in one modular width (MW). Thus more protection devices can be installed in the distribution board and existing installations can easily be expanded with new protection functions in a space-saving solution. The protection devices can also be connected in a 5SM6 AFD unit - thus offering personal, line and preventive fire protection.
