Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1424-1RC40

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1424-1RC40

The Siemens 5SU1424-1RC40 is a Betagard RCBO (Residual Current Breaker with Overload Protection) designed to provide complete protection for people, electrical wiring, and connected equipment in low-voltage distribution systems. It combines the functions of an MCB and RCCB in a single compact device, ensuring protection against earth leakage, overload, and short-circuit faults.

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

It is commonly used in residential buildings, commercial distribution boards, and light industrial installations, where safe and space-efficient protection is required.
