Eti-Polam EFI-4 Residual Current Circuit Breaker 4P 80A 30mA Type AC

The Eti-Polam EFI-4 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in both residential and industrial environments. This device is designed to detect and interrupt circuits when earth leakage currents are present, significantly reducing the risk of electric shock and preventing potential fire hazards caused by insulation faults. With a robust construction and reliable switching mechanism, it serves as a critical component in modern electrical distribution boards, ensuring the safety of personnel and the protection of connected equipment.

Advantages

The primary advantage of the Eti-Polam EFI-4 lies in its high sensitivity and reliable operation under standard AC electrical conditions. Its 4-pole configuration allows for versatile application in three-phase systems, providing comprehensive protection across all phases and the neutral conductor. The device is built to withstand demanding operational environments, offering long-term durability and consistent performance. By integrating this RCCB into your electrical system, you gain a dependable safeguard that reacts quickly to leakage currents, thereby maintaining the integrity of your electrical installation and enhancing overall safety standards.

Suitable for

• Residential electrical distribution boards
• Industrial machinery and equipment protection
• Commercial building electrical systems
• Protection of circuits with sensitive electronic loads

This device may not be suitable for applications requiring protection against DC components or pulsating DC leakage currents, as it is specifically designed as a Type AC breaker. It is also not intended for use in environments where the leakage current characteristics exceed the standard AC sinusoidal waveform requirements.

Key specifications

• Number of poles: 4
• Rated current: 80A
• Rated residual operating current: 30mA
• Type: AC

Installation of the Eti-Polam EFI-4 should be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly connected to the input terminals and that the load is properly wired to the output terminals. After installation, it is recommended to use the integrated test button to verify the mechanical functionality of the breaker.

What to consider before purchase

• Verify that the 80A rated current matches the requirements of your circuit
• Ensure the 30mA sensitivity is appropriate for your specific safety needs
• Confirm that the installation environment is compatible with Type AC residual current devices
• Check the available space in your distribution board for a 4-pole module

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.
