Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1424-1RC42

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1424-1RC42

The Siemens 5SU1424-1RC42 is a Betagard RCBO (Residual Current Breaker with Overload Protection) designed to deliver complete protection for people, electrical wiring, and connected equipment in low-voltage distribution systems. It combines MCB + RCCB functions in a single compact device, providing protection against earth leakage, overload, and short-circuit faults.

This device is of Type AC residual current detection, suitable for standard sinusoidal AC leakage currents, and is intended for conventional electrical loads. The C-characteristic curve ensures reliable operation under moderate inrush currents such as those from lighting circuits, socket outlets, small motors, and inductive loads.

The 5SU1424 series is widely used in residential buildings, commercial distribution boards, and light industrial installations, where compact design and high safety performance are required.

According to Siemens Betagard technical specifications, this series offers 30 mA / 100 mA sensitivity options, 10 kA breaking capacity, DIN rail mounting, and compliance with IEC 61009-1 standards.
