Residual current protective device 5SU1 354-1KK10
Manufacturer: Siemens
5SU1 354-1KK10 series RCBOs are a combination of an RCCB and a miniature circuit breaker in a compact design for personnel, fire and line protection.
RCBOs with a rated residual current of 30mA are used for personnel, material and fire protection, as well as for protection against direct contact.
The MCB part of the RCBO protects lines against overload and short circuits. Additional components of the 5SY miniature circuit breakers can be mounted at the side and carry out additional functions.
RCBOs comprise one part for fault-current detection and one part for overcurrent detection. They are equipped with a delayed overload/time-dependent thermal release (thermal bimetal) for low overcurrents and with an instantaneous electromagnetic release for higher overload and short-circuit currents.
