Combined overcurrent and residual current protection 6 kA breaking capacity Type A RCD for AC and pulsating DC detection B-characteristic tripping for sensitive applications Compact 1P+N design

Product description

The Siemens 5SU1356-6KK13 is a Residual Current Breaker with Overcurrent protection (RCBO) offering a 6 kA breaking capacity. This 1-pole plus neutral device is equipped with Type A RCD sensitivity, ensuring detection of both AC and pulsating DC residual currents, alongside a 30 mA rated residual current. It features a B-characteristic tripping curve, best suited for circuits with low inrush currents, and a nominal current (In) of 13 A, operating at 230 V AC.

This RCBO is a good choice for applications where sensitive protection against earth faults and overcurrents is required, such as in residential installations or for protecting sensitive electronic equipment. The B-characteristic provides enhanced safety by reacting to lower levels of overcurrent compared to C or D characteristics.
