Betagard Residual Current Breaker Operator, Type A with C characteristic – 5SU1354-1RC25

Product Description

The Siemens 5SU1354-1RC25 is a high-performance Betagard Residual Current Breaker Operator (RCBO) designed to provide complete protection against overload, short circuit, and earth leakage faults in low-voltage electrical distribution systems.

It features Type A residual current protection, which detects both sinusoidal AC and pulsating DC leakage currents, ensuring enhanced safety compared to Type AC devices. With a C-characteristic tripping curve, it is suitable for circuits with moderate inrush currents such as lighting systems, socket outlets, HVAC equipment, and small motor loads.

With a 25A rated current, this RCBO is ideal for residential, commercial, and light industrial applications, ensuring safe, stable, and reliable electrical distribution.
