Comprehensive protection for your electrical system

The Siemens RCBO, integrates three basic protections:

  • Magnetic protection against short circuits, preventing fire and damage to the system
  • Thermal protection against overloads, preventing interruptions due to excessive loads
  • Differential protection (30mA) against current leakage, ensuring the safety of people

This combination makes it an essential device for electrical safety in homes, offices and small businesses.

Siemens RCBO: curve C and type A protection

C curve: ideal protection for mixed loads

Thanks to the C-curve tripping curve, the device is suitable for circuits with mixed loads, such as outlets and lighting, reducing the risks of unwanted interruptions.

Operation of the type A residual current circuit breaker

The A-type residual current device provides excellent protection against alternating sine and pulsating unidirectional leakage currents. This means that it can detect even leakage currents with continuous components, ensuring a higher level of safety than AC-type differential switches.

Siemens RCBO: robustness, reliability and compliance

Robust and compact design

Designed for quick and easy DIN-rail installation, the device is 2 modules wide, taking up little space in the electrical panel. Constructed with halogen- and silicone-free materials, it provides enhanced environmental safety and durability.

Certified reliability and regulatory compliance

Made in accordance with CEI EN 61008-1 standards, it ensures safe and timely tripping of sine-sine alternating differential currents. It has a mechanical life of 10,000 switching cycles, ensuring reliable performance over time.
