The Eti-Polam EFI-2 F is a high-performance 2-pole residual current circuit breaker engineered to provide robust electrical protection in modern residential and commercial environments. This device is specifically designed to monitor electrical circuits for leakage currents, effectively preventing electric shock and mitigating fire risks. By utilizing advanced Type F technology, it ensures reliable operation even in systems that incorporate complex electronic components, such as frequency converters and variable speed drives, which often generate pulsating DC components that standard breakers may fail to detect.
Advantages
The primary advantage of the Eti-Polam EFI-2 F lies in its specialized Type F design, which offers superior immunity to nuisance tripping compared to standard AC or A-type devices. This makes it an essential component for installations featuring modern power electronics. Its robust construction ensures long-term operational stability, while the 2-pole configuration allows for seamless integration into single-phase electrical distribution boards. The device provides a high level of safety by accurately identifying both sinusoidal AC and pulsating DC residual currents, ensuring comprehensive protection for sensitive equipment and personnel.
Suitable for
- Residential electrical installations with modern appliances
- Commercial buildings utilizing frequency converters
- Systems with variable speed drives and heat pumps
- Protection of circuits containing complex electronic loads
When it may not be suitable
This device is not intended for use in DC-only electrical systems or high-voltage industrial grids that exceed its specified operational parameters. It may also be unnecessary for simple, purely resistive lighting circuits where a standard AC-type residual current device would suffice.
Key specifications
- Number of poles: 2
- Rated current: 40A
- Rated residual operating current: 30mA
- Type: F
How to use
The Eti-Polam EFI-2 F must be installed by a qualified electrician in accordance with local electrical safety regulations. It is typically mounted on a standard DIN rail within a distribution board. Once installed, the device should be connected to the phase and neutral conductors of the circuit it is intended to protect. After installation, the integrated test button should be pressed to verify that the mechanism trips correctly, ensuring the device is fully functional before the circuit is put into regular service.
What to consider before purchase
- Verify that the rated current of 40A matches the requirements of your circuit
- Ensure the 30mA sensitivity is appropriate for the intended level of personnel protection
- Confirm that the installation environment supports a 2-pole device
Usage recommendations: It is recommended to perform a manual test of the residual current circuit breaker using the test button at least every six months to ensure the mechanical parts remain operational and the device continues to provide the intended level of safety.
