Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1424-1RC41

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1424-1RC41

The Siemens 5SU1424-1RC41 is a Betagard RCBO (Residual Current Breaker with Overload Protection) designed to provide complete protection for human safety, electrical wiring, and connected equipment in low-voltage distribution systems. It integrates MCB + RCCB functionality in a single modular device, ensuring protection against earth leakage, overload, and short-circuit faults.

This model uses Type AC residual current detection, suitable for pure sinusoidal AC leakage currents, and is ideal for standard electrical loads. The C-characteristic tripping curve ensures reliable operation under moderate inrush currents such as lighting circuits, socket outlets, and small inductive loads.

It is widely used in residential, commercial, and light industrial distribution boards, where compact size, safety, and reliability are essential.

According to Siemens Betagard RCBO technical specifications, this series supports 30–100 mA residual current sensitivity options, 10 kA breaking capacity, DIN rail mounting, and compliance with IEC 61009 standards.
