Eaton PFIM-63/4/003-G Residual Current Circuit Breaker 4P 63A 30mA Type AC

The Eaton PFIM-63/4/003-G is a high-quality 4-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in both residential and commercial environments. This device is designed to monitor electrical circuits for leakage currents and automatically disconnect the power supply if a fault is detected, thereby protecting users from electric shock and preventing potential fire hazards caused by insulation failures.

Advantages

This residual current circuit breaker offers robust performance and high reliability for modern electrical systems. Its 4-pole configuration allows for versatile installation in three-phase systems, while the 63A rated current capacity ensures it can handle significant electrical loads without compromising safety. The device is built to meet stringent safety standards, providing consistent protection against fault currents and ensuring that electrical installations remain secure and compliant with safety regulations.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Protection of circuits with standard AC-type loads
• General electrical safety in multi-phase installations

When it may not be suitable

This device is a Type AC RCCB, which is designed to detect sinusoidal AC residual currents. It may not be suitable for circuits containing electronic equipment that produces DC components or high-frequency leakage, such as certain types of variable speed drives or complex power electronics, where Type A or Type B breakers would be required.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Rated residual operating current: 30mA
• Type: AC

How to use

The Eaton PFIM-63/4/003-G must be installed by a qualified electrician in accordance with local electrical codes and regulations. It is typically mounted on a standard DIN rail within a distribution board. Once installed, the device should be tested periodically using the integrated test button to ensure the mechanical tripping mechanism remains functional and responsive to fault conditions.

What to consider before purchase

• Ensure the rated current matches your circuit requirements
• Verify that the installation environment is compatible with Type AC protection
• Check the number of phases in your electrical system
• Confirm the device fits your existing distribution board layout

Usage recommendations

Regular testing of the residual current circuit breaker via the test button is recommended at least every six months to verify the integrity of the protection system.
