Eaton mRB6-16/3N/C/003-A (120660) – Residual Current Circuit Breaker with Overcurrent Protection (RCBO) 3 + N, 16 A, 30 mA, characteristic curve C
The Eaton mRB6-16/3N/C/003-A is a compact and powerful combination of residual current device (RCD) and overcurrent/short-circuit breaker (MCB) for three-phase circuits with a neutral conductor. With a rated current of 16 A, a residual current tripping current of 30 mA, and a C-curve characteristic, this device offers reliable protection in residential, commercial, and industrial applications.
Key features
- Rated current 16 A – suitable for medium-sized consumer groups.
- Residual current tripping 30 mA – meets personal protection and fire protection requirements.
- Characteristic curve C – indicates a higher tripping characteristic in case of overcurrent, ideal for inductive loads or starting currents.
- Number of poles 3 + N – three phases and neutral conductor are switched off together.
- Combined device FI + LS – combines residual current and overcurrent protection in one device, saving space in the distribution board.
- Suitable for DIN rail mounting – simple and standard-compliant installation.

Advantages for your installation
The Eaton mRB6-16/3N/C/003-A offers a highly integrated protection solution that combines both overcurrent and residual current protection in a single module – saving space and installation effort in the distribution board. This type is particularly suitable for modern three-phase distribution boards where even smaller groups of consumers need to be protected while simultaneously meeting personal safety and fire protection requirements.
Areas of application
- Three-phase distribution systems in residential or commercial buildings, especially with a neutral conductor.
- Connections with medium current load (e.g., smaller machines, charging points, distribution groups).
- Areas where both residual current monitoring (30 mA) and overcurrent protection with selective characteristic C are required.
- Installations with limited space in the distribution box – through the combination of RCD and MCB in one device.
Conclusion
The Eaton mRB6-16/3N/C/003-A (120660) is a reliable choice for combined fault and overcurrent protection in three-phase systems with a neutral conductor. Its 16 A rated current, 30 mA residual current tripping, and C-curve characteristic make it ideal for demanding installations where protection, safety, and space optimization are equally important.
