When it may not be suitable

This device is specifically designed for applications requiring Type B protection. It may not be necessary or cost-effective for simple residential circuits that only require standard Type AC or A protection. Additionally, it is not intended for use in environments exceeding its specified voltage or current ratings.

Key specifications

• Number of poles: 2
• Rated current: 40A
• Rated residual current: 30mA
• Type: G/B (Short-time delayed, sensitive to all currents)
• Short-circuit capacity: 10kA

How to use

The Eaton FRCdM-40/2/003-G/B 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 a distribution board. Ensure that the supply cables are correctly connected to the input terminals and the load is connected to the output terminals, observing the correct polarity and torque specifications provided in the installation manual.

What to consider before purchase

• Verify that the Type B protection is required for your specific equipment.
• Ensure the 40A rating matches your circuit load requirements.
• Check the available space in your distribution board for a 2-pole device.
• Confirm compatibility with existing upstream and downstream protection devices.

Usage recommendations

Regularly test the device using the integrated test button to ensure the mechanical and electrical tripping mechanism remains functional. It is recommended to perform this check at least every six months or as required by local safety standards for industrial installations.
