Siemens 5SU1 RCBOs


The 5SU1 series from Siemens are a range of RCBOs in a compact design. Rated with a residual current of maximum 30 mA is suitable for personnel, material and fire protection, as well as for protection against direct contact.

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.

Conductor connection easily checked in front of the busbar
Large accessible wiring space enables easy insertion of conductor in the terminals
The surge current withstand capability of > 1 kA ensures safe and reliable operation
All additional components for miniature circuit breakers can be retrofitted on the right-hand side
