## Summary description

Three-phase residual-current circuit breaker ETI EFI6-P4 designed for protection against earth-fault and leakage currents. Rated current 40 A, residual operating current 30 mA, Type A detection, nominal voltage 415 V and frequency 50/60 Hz. Intended for mounting on TH35 DIN rail (IP20). Suitable for industrial and commercial distribution boards to protect personnel and equipment.

## Long description

The ETI EFI6-P4 three-phase residual-current circuit breaker provides earth-fault and leakage current protection for industrial and commercial electrical distribution systems. Rated for a nominal current of 40 A and a residual operating current of 30 mA, this Type A device is designed for protection of people and connected equipment on 415 V systems at 50/60 Hz. The unit is intended for snap-on mounting to a TH35 DIN rail and features an IP20 enclosure suitable for installation inside distribution enclosures and switchboards.
Advantages
The device combines sensitivity to AC and pulsating DC residual currents (Type A) with a compact three-pole design, offering coordinated protection across three phases. With a 30 mA residual operating threshold it provides a standard level of personal protection, while the 40 A rated current supports typical branch and feeder circuits in commercial and light-industrial panels. DIN-rail mounting and IP20 protection enable easy integration into existing switchgear layouts.
Suitable for
Protection of personnel and equipment in three-phase distribution boards
Commercial and light-industrial electrical panels and feeder circuits
Applications where sensitivity to AC and pulsating DC leakage is required (Type A)
Installations using TH35 DIN-rail enclosures with internal IP20-rated compartments
When it may not be suitable
This residual-current circuit breaker is not intended for outdoor or unenclosed installations where a higher ingress protection rating is required. It is also not suitable where sensitivity to DC-only residual currents (Type B requirements) or alternative rated currents and trip thresholds are necessary; in such cases a different device type or rating should be selected.
Key specifications
Poles: three-phase (3-pole)
Rated current: 40 A
Residual operating current (sensitivity): 30 mA
Tripping characteristic: Type A (detects AC and pulsating DC leakage)
Nominal voltage: 415 V
Frequency: 50/60 Hz
Mounting: TH35 DIN-rail (snap-on)
Enclosure protection: IP20 (for indoor use inside distribution enclosures)
How to use
Mount the breaker onto a TH35 DIN rail inside a suitable distribution enclosure with IP20-rated internal compartments. Connect the three phase conductors and the line-side and load-side wiring according to the wiring diagram and local electrical codes. Ensure the protective earth conductor and neutral are handled per installation standards. After wiring, test the device by applying the manufacturer-recommended test procedure to verify correct tripping at residual currents. Commission the circuit only after confirming correct polarity and secure terminals.
What to consider before purchase
Verify that a 40 A rated current and 30 mA residual sensitivity meet your circuit protection and safety requirements
Confirm that Type A detection (AC and pulsating DC) is appropriate for the connected loads
Ensure your distribution enclosure supports TH35 DIN-rail mounting and provides IP20 internal protection
Check coordination requirements with upstream and downstream protective devices in the distribution system
Usage recommendations
Install and commission this device following national wiring regulations and the manufacturer's installation instructions. Perform periodic functional tests to confirm residual-current operation and integrate the breaker into a documented maintenance schedule for distribution equipment.
