Betagard
Residual Current Breaker Operator, Type A with C Characteristic – 5SU1354-1RC20
The Siemens 5SU1354-1RC20
is a reliable 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.
This device
features Type A residual current protection, which detects both sinusoidal
AC and pulsating DC leakage currents, ensuring higher safety compared to
Type AC devices. With a C-characteristic tripping curve, it is ideal for
circuits with moderate inrush currents such as lighting systems, socket
outlets, HVAC equipment, and small motor loads.
With a 20A
rated current, it is widely used in residential, commercial, and light
industrial applications, ensuring safe, stable, and continuous electrical
operation.
