Suitable for
Industrial power distribution boards
Commercial building electrical systems
Large-scale machinery and equipment protection
Three-phase electrical installations requiring leakage current monitoring
When it may not be suitable
This device is not intended for use in circuits requiring DC component detection, as it is a Type AC residual current circuit breaker. It is also not suitable for residential applications where a higher sensitivity, such as 30mA, is required for direct contact protection.
Key specifications
Number of poles: 4
Rated current: 125A
Rated residual current: 0.3A
Type: AC
How to use
The Eaton FRCmM-125/4/03 must be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is typically mounted on a standard DIN rail within an electrical 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 alignment. After installation, the device should be tested using the integrated test button to verify its mechanical functionality and tripping mechanism.
What to consider before purchase
Verify that the 0.3A sensitivity meets your specific safety requirements.
Ensure the 125A rated current is compatible with your circuit load.
Confirm that a Type AC device is appropriate for your specific electrical installation.
Check the available space in your distribution board for a 4-pole device.
Usage recommendations
Regularly test the residual current circuit breaker using the built-in test button at least every six months to ensure the tripping mechanism remains operational and responsive to potential faults.
