Betagard Residual Current Breaker Operator, Type A with C characteristic – 5SU1354-7RC40

Product Description

Betagard Residual Current Breaker Operator, Type A with C Characteristic – 5SU1354-7RC40

The Siemens 5SU1354-7RC40 is a Betagard RCBO (Residual Current Breaker with Overload Protection) designed to provide complete protection for people, wiring, and electrical equipment in low-voltage distribution systems. It combines the functions of an MCB + RCCB in a single compact device, ensuring protection against earth leakage, overload, and short-circuit faults.

This device features Type A residual current detection, making it suitable for modern electrical installations with electronic loads, inverter-based equipment, LED lighting, and IT systems, where both AC and pulsating DC leakage currents may occur. The C-characteristic curve ensures reliable operation under moderate inrush currents such as motors and inductive loads.

It is widely used in residential, commercial, and light industrial distribution boards, where space-saving design and high safety performance are required.
