## Summary description

The Eaton FRCMM-125/4/03-A is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety and fault protection. It features a rated current of 125A and a sensitivity of 300mA, utilizing Type A protection for AC and pulsating DC residual currents. This device is essential for preventing electric shock and fire hazards in industrial and commercial electrical distribution systems.

## Long description

The Eaton FRCMM-125/4/03-A is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide reliable electrical safety and fault protection in demanding environments. This device is specifically designed to detect and interrupt residual currents, effectively mitigating the risks of electric shock and fire hazards within electrical distribution networks. By monitoring the balance of current in a circuit, it ensures rapid disconnection when a fault is detected, maintaining the integrity of the installation.
Advantages
This residual current circuit breaker offers robust protection by supporting both AC and pulsating DC residual currents, which makes it a versatile solution for modern electrical systems containing electronic components. Its high rated current capacity of 125A allows it to handle significant electrical loads, making it suitable for heavy-duty applications. The device is built with high-quality materials to ensure long-term operational reliability and consistent performance under various environmental conditions, providing peace of mind for facility managers and electrical engineers.
Suitable for
Industrial electrical distribution systems
Commercial building power management
Protection of circuits with electronic equipment
Installations requiring Type A residual current detection
When it may not be suitable
This device is not intended for residential applications where lower current ratings are typically required. It is also not suitable for protecting against short circuits or overloads, as it functions exclusively as a residual current protection device and must be paired with appropriate circuit breakers or fuses.
Key specifications
Number of poles: 4
Rated current: 125A
Rated residual operating current: 300mA
Protection type: Type A
Application: AC and pulsating DC residual currents
How to use
The Eaton FRCMM-125/4/03-A must be installed by a qualified electrician in accordance with local electrical regulations. It is typically mounted on a standard DIN rail within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and that the load is connected to the output terminals, observing the correct polarity and torque specifications provided in the technical documentation. After installation, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.
What to consider before purchase
Verify that the 300mA sensitivity is appropriate for your specific fire protection or safety requirements.
Ensure the 125A rating matches the maximum load of your electrical circuit.
Confirm that the installation environment is compatible with the device's physical dimensions and mounting requirements.
Usage recommendations
Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the mechanism remains operational and that the device continues to provide the intended level of safety.
