Siemens RCBO – Compact Residual Current Circuit Breaker with Overcurrent Protection for Electrical Installations
The Siemens RCBO combines residual current and overcurrent protection in a compact device. It is designed for use in distribution boards and provides reliable protection against fault currents, overloads, and short circuits.
Compact design with only 1 TE saves valuable space in the distribution board
Type A fault current detection protects against pulsating DC fault currents
Rated current 16 A suitable for common circuits in residential and commercial buildings
Rated short-circuit capacity 6 kA for safe disconnection in case of short circuit
2-pole version combines RCD and MCB functions in one unit
What sets the RCBO apart
This combined circuit breaker reduces installation effort and saves space by integrating two functions in one device. Thanks to the Type A characteristic, modern electrical appliances with rectified fault currents are also reliably detected.
Ideal for...
Electricians, homeowners, and planners who want to achieve standard-compliant personal and fire protection in space-limited distribution boards. Suitable for new installations and retrofits in residential and commercial buildings.
How to use the RCBO
Mount the device on a DIN rail in the distribution board. Ensure correct connection of phase and neutral. After installation, test the function using the test button.
