Residual current residual current circuit breaker 5SU1 series

overcurrentoverloadlow-voltage

5SU1 RCBOs in 2-, 3-, and 4-pole versions combine residual current circuit breakers and miniature circuit breakers in one device. They protect people from fault currents and systems from short circuits and overloads. They ensure all-pole protection of final circuits with 2, 3 or 4 outer conductors as well as protection of the N conductor against overload due to harmonics in non-linear consumers such as PC power supplies, energy-saving lamps or consumer electronics. The compact 5SV1 RCBOs reliably protect different electrical circuits against fault currents. They combine residual current detection and overcurrent protection in just one modular width (MW) and ensure reliable personal and cable protection in numerous areas of application with just one device. • Space savings of 50% thanks to a compact solution for residual current and line protection • Simple retrofit in existing systems thanks to the same design • Easy integration on DIN rails thanks to slider actuation • Possibility of adding a 5SM6 AFD unit for protection against fault currents, overcurrent, short-circuits and arcing faults in just two modular widths The residual current protective devices (RCDs) from the SENTRON portfolio offer the right solution for every application. All RCDs are available in different types and versions suited to detecting different types of residual current and different areas of application.
