Siemens 5SU1354-7KK40 RCBO - 40A, 10kA, Type A

The Siemens 5SU1354-7KK40 is a high-performance Residual Current Breaker with Overcurrent protection (RCBO), featuring a robust 10 kA breaking capacity. This 1-pole plus neutral device is equipped with Type A RCD sensitivity, capable of detecting AC and pulsating DC residual currents, and a 30 mA leakage current threshold. It has a C-characteristic tripping curve, suitable for loads with moderate inrush, and a nominal current (In) of 40 A, operating at 230 V AC.

This RCBO is designed for main circuit protection or protection of significant loads in industrial and commercial installations where higher current ratings are required. It provides essential safety by combining overcurrent protection (overloads and short circuits) with residual current protection, minimizing risks of electric shock and fire hazards. The C-characteristic is generally preferred for circuits supplying equipment with moderate inrush currents.
