The Siemens RCBO combines a residual current device (RCD) and a miniature circuit breaker (MCB) in one compact unit. It protects people from dangerous fault currents and protects cables and equipment from overload and short circuits.
4-pole version for three-phase networks: Enables use in commercial and industrial applications with three-phase power.
Residual current protection type A with 30 mA: Provides enhanced personal protection against sinusoidal and pulsating fault currents.
Tripping characteristic C, rated current 16 A: Suitable for loads with high inrush current, such as motors and transformers.
Compact design with 4 module units: Saves space in the distribution board and enables efficient installation.
24 months manufacturer's warranty: Ensures long-term investment security and confidence in Siemens quality.
What sets the Siemens RCBO apart
By combining RCD and MCB protection in one device, the Siemens RCBO reduces wiring effort and requires less space in the distribution board than two separate units. Siemens quality ensures reliable and long-lasting operation under demanding conditions. The device is tested and certified according to current standards.
Ideal for...
This RCBO is particularly suitable for electricians, building managers, and industrial companies who need efficient and safe power distribution in three-phase networks. It is the first choice for new installations as well as upgrades in commercial and industrial buildings.
How to use the Siemens RCBO
Installation must be carried out by a qualified electrician in compliance with applicable regulations. The device snaps onto a DIN rail in the distribution board. After connecting the cables, a functional test of the RCD part must be performed.
Siemens is a global technology powerhouse headquartered in Germany, focusing on electrification, automation, and digitalization. Siemens electrical installation products are known for high quality, reliability, and safety in commercial and industrial applications.
