## Summary description

The Eaton FRCMM-125/4/05 is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety and protection against leakage currents. It features a rated current of 125A and a sensitivity of 0.5A, operating on Type AC characteristics. This device is essential for preventing electrical hazards in industrial and commercial power distribution systems, ensuring reliable circuit interruption when fault currents are detected.

## Long description

The Eaton FRCMM-125/4/05 is a high-capacity 4-pole residual current circuit breaker (RCCB) engineered to provide robust electrical protection in demanding environments. This device is specifically designed to detect and interrupt leakage currents, thereby preventing potential electrical hazards and ensuring the safety of both personnel and equipment. With a rated current of 125A and a sensitivity threshold of 0.5A, it serves as a critical component in maintaining the integrity of industrial and commercial power distribution networks.
Advantages
This residual current circuit breaker offers exceptional reliability in monitoring electrical circuits for fault currents. Its 4-pole configuration allows for versatile application in three-phase systems, providing comprehensive protection across all phases and the neutral conductor. The Type AC characteristic ensures effective operation in standard electrical installations where sinusoidal alternating residual currents are present. By integrating this device into your electrical infrastructure, you benefit from a durable solution that minimizes downtime and enhances overall system safety through precise and rapid fault detection.
Suitable for
Industrial power distribution systems
Commercial building electrical installations
Protection of heavy-duty machinery and equipment
Main circuit protection in large-scale electrical panels
When it may not be suitable
This device is not intended for use in circuits where DC components or pulsating DC residual currents are present, as it is specifically designed for Type AC applications. It is also not suitable for residential applications requiring high-sensitivity protection, such as 30mA devices used for direct contact protection.
Key specifications
Number of poles: 4
Rated current: 125A
Rated residual operating current: 0.5A
Type: AC
Application: Industrial and commercial power distribution
How to use
The Eaton FRCMM-125/4/05 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, maintaining proper phase and neutral alignment. 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 0.5A sensitivity meets your specific safety requirements for equipment protection.
Ensure the 125A rated current is compatible with your circuit load.
Confirm that the installation environment is suitable for Type AC residual current devices.
Check the physical dimensions to ensure compatibility with your existing distribution board space.
Usage recommendations
Regularly test the 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 protection.
