Product Description
Betagard Residual Current Breaker Operator, Type AC with
C Characteristic – 5SU1344-7RC32
🔹 Description
The Siemens Betagard Residual Current Breaker Operator
(RCBO) 5SU1344-7RC32 is a high-performance protective device designed
for safe and reliable electrical distribution systems. It combines residual
current protection and overload/short-circuit protection in a compact
modular design.
This Type AC device is engineered to detect sinusoidal AC
residual currents, ensuring effective protection against electric shock and
fire hazards. With C-characteristic tripping, it provides optimal
performance for circuits with moderate inrush currents such as lighting and
socket outlets.
Built for DIN rail mounting, it ensures easy installation,
high operational reliability, and long service life in residential, commercial,
and industrial applications.
