Eaton PFIM-100/4/03 Residual Current Circuit Breaker, 4-Pole, 100A, 0.3A, Type AC

The Eaton PFIM-100/4/03 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide robust protection against electrical faults in various distribution systems. This device is designed to monitor electrical circuits and automatically disconnect power when a residual current is detected, thereby safeguarding personnel and equipment from potential hazards. With its reliable construction and adherence to international safety standards, it serves as a critical component for maintaining electrical integrity in demanding environments.

Advantages

This residual current circuit breaker offers exceptional reliability and consistent performance in monitoring electrical circuits. Its 4-pole configuration allows for versatile application in three-phase systems, ensuring comprehensive protection across all phases and the neutral conductor. The device is built to withstand rigorous operational conditions, providing long-term stability and peace of mind for facility managers and electrical installers. By integrating this component into your electrical infrastructure, you ensure a high level of safety and compliance with modern electrical regulations.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Three-phase electrical installations
• Protection of electrical circuits against residual currents

When it may not be suitable

This device is a Type AC residual current circuit breaker, which is designed to detect sinusoidal AC residual currents. It may not be suitable for circuits containing electronic equipment that generates DC components or high-frequency currents, as these may interfere with the tripping mechanism. For such applications, a Type A or Type B device would be required.

Key specifications

• Number of poles: 4
• Rated current: 100A
• Rated residual operating current: 0.3A
• Device type: AC

How to use

The Eaton PFIM-100/4/03 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 and neutral alignment. After installation, the device should be tested using the integrated test button to verify its mechanical functionality.

What to consider before purchase

• Verify that the 100A rated current matches the requirements of your electrical circuit.
• Ensure that the 0.3A sensitivity is appropriate for your specific safety application.
• Confirm that the installation environment is compatible with a Type AC residual current device.
• Check the available space in your distribution board for a 4-pole module.

Usage recommendations

Regular testing of the residual current circuit breaker using the built-in test button is recommended at least every six months to ensure the device remains in optimal working condition and continues to provide the intended level of protection.
