The Siemens 5SU1356-6KK16 is a DIN Rail Mountable Residual Current Operated Circuit Breaker (RCCB) of Characteristic Type B. This 16A circuit breaker is suitable for use in three-phase current systems before input circuits with rectifiers. It is not intended for use in DC systems and in networks with operating frequencies other than 50Hz or 60Hz.
With Type B, the tripping characteristic is adapted to suit the increase of leakage currents at higher frequencies in systems with capacitive impedances, thus ensuring greater operating safety.
Applications include frequency converters, medical devices and UPS systems.
