Eti-Polam EFI6-P4 Residual Current Circuit Breaker, 4-Pole, 63A, 0.03A, Type A, 6kA

The Eti-Polam EFI6-P4 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 earth leakage currents and automatically disconnect the circuit, effectively preventing electrical hazards. With a robust construction and reliable switching mechanism, it serves as a critical component in modern electrical distribution systems, ensuring protection for both personnel and equipment.

Advantages

The primary advantage of this residual current circuit breaker is its Type A classification, which allows it to detect not only standard AC residual currents but also pulsating DC components, providing a higher level of safety compared to standard AC-only devices. Its 63A rated current and 0.03A sensitivity make it highly effective for general protection against direct contact. The 6kA breaking capacity ensures that the device can handle significant fault currents, maintaining system integrity under demanding conditions. Its 4-pole design allows for versatile application in three-phase electrical installations.

Suitable for

• Residential electrical distribution boards
• Industrial machinery and equipment protection
• Commercial building electrical systems
• Protection against earth leakage in three-phase circuits

When it may not be suitable

This device is not intended for use in circuits where the load exceeds 63A, as this would cause overheating and potential failure. It is also not suitable for protecting against short-circuit or overload conditions, as it is strictly an RCCB and must be paired with a miniature circuit breaker or fuse to provide complete circuit protection.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Rated residual operating current: 0.03A
• Type: A (AC and pulsating DC)
• Breaking capacity: 6kA

How to use

The installation of the Eti-Polam EFI6-P4 must be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for DIN-rail mounting within a distribution board. Ensure that all line and neutral conductors are correctly connected to the designated terminals. After installation, the device should be tested using the integrated test button to verify that the tripping mechanism functions correctly. Regular testing is recommended to ensure ongoing operational safety.

What to consider before purchase

• Verify that the rated current matches your circuit requirements
• Ensure the 0.03A sensitivity is appropriate for your specific safety needs
• Confirm that the 4-pole configuration is compatible with your electrical supply
• Check that the installation space in your distribution board is sufficient

Usage recommendations

Regularly press the test button at least once every six months to ensure the mechanical integrity of the tripping mechanism. If the device fails to trip during testing, it must be replaced immediately to maintain electrical safety.
